La endometriosis es tejido parecido al revestimiento del útero que crece fuera de él: en los ovarios, la pared pélvica y a veces más allá. Depende de los estrógenos y se inflama al compás del ciclo menstrual. El dolor es real, y se desestima con la frecuencia suficiente como para que la mujer media espere años hasta un diagnóstico. Responde al tratamiento.
La forma con mejor evidencia de calmar el dolor es aquietar el estrógeno que impulsa los depósitos, con el progestágeno dienogest, la píldora combinada o los fármacos GnRH. Para la enfermedad confirmada que sigue doliendo, la cirugía laparoscópica para extirpar o destruir los depósitos alivia el dolor y aumenta las probabilidades de embarazo. Debajo de todo ello está lo que tú controlas: la alimentación antiinflamatoria, el movimiento constante, la fisioterapia del suelo pélvico y el seguimiento de tu propio patrón. Si el objetivo es el embarazo, el plan cambia, porque los tratamientos que aquietan el dolor también impiden la concepción, de modo que la fertilidad se aborda como su propia tarea, desde el principio.

What It Is
Endometriosis is tissue like the uterine lining growing outside the uterus, on the ovaries, the pelvic wall, the uterine ligaments, and sometimes the bowel or bladder. It is an estrogen-dependent, inflammatory disease: the deposits inflame and bleed roughly in step with the cycle. That is why the pain tends to track the period, and why treatments that quiet estrogen help.
About one in ten women of reproductive age is affected. The most common form is pain: painful periods, pain deep during sex, and pain that spreads through the month. It can also make conceiving harder, and it can form cysts on the ovary.
Its pain is real, and calling it ordinary period pain is a large part of why diagnosis lags first symptoms by several years. Endometriosis is often missed on an ultrasound scan and confirmed only when a surgeon looks inside at laparoscopy, so a normal scan does not rule it out.
Pain that stops you working, studying, or living your day is a reason to ask for proper assessment.
Endometriosis is really three problems under one name, and the treatment layered on top differs for each:
- Controlling pain, the day-to-day and cyclical pain the disease causes.
- Protecting or pursuing fertility, where conceiving is the goal.
- Dealing with an ovarian cyst, an endometrioma, a pocket of old blood on the ovary.
What Helps
Endometriosis responds to treatment. Its three problems (pain, fertility, and an ovarian cyst) each draw on a different mix of treatments.
Quieting the estrogen signal, the first-line medical treatment
Because the pain tracks the estrogen behind the deposits, the best-evidenced medical treatments quiet that signal, and current guidelines make them first-line for pain. All of them prevent pregnancy while taken, so the plan changes when conceiving is the goal.
- Dienogest, a 2 mg progestin taken as a daily tablet, lowered pelvic pain by 12.3 mm more than a placebo on a 100 mm scale over 12 weeks. Against a stronger GnRH agonist injection, it matched the pain relief over 24 weeks without the bone loss that drug causes. Spine density rose 0.25% on dienogest and fell about 4% on the GnRH drug. Kept up for about a year, its pain relief deepened and lasted for months after stopping.
- The combined pill, often taken continuously to skip the bleed, is where many women start. Its trial evidence in endometriosis is thin and low-certainty, so that first-line use rests on long clinical experience and convenience more than strong data.
- The GnRH drugs give the strongest suppression, usually paired with a little add-back hormone to limit the bone loss and hot flashes they otherwise cause.
Everyday pain relief
Anti-inflammatory painkillers, the NSAIDs such as naproxen or ibuprofen, are the common first step for day-to-day pain, taken around the period when cramping peaks. The trial evidence in endometriosis specifically is very thin: the one small trial that could be pooled, in 24 women, could not show a clear effect either way. They stay a reasonable first thing to try, and carry the usual stomach and kidney effects with regular use.
Surgery when the pain persists
Across 10 randomized trials of 973 women with mild to moderate disease, keyhole surgery to remove the deposits beat a look-only operation. It reduced overall pain and raised the chance of live birth or ongoing pregnancy. For disease that keeps hurting after hormonal treatment, excision or ablation is a well-evidenced, mainstream option. Excision (cutting deposits out) and ablation (burning them off) performed similarly for pain in the one head-to-head study.
The same laparoscopy that treats the deposits also confirms the diagnosis, so for many women a single operation does both. Pain can return over time, so surgery is planned around the goal, whether pain relief or fertility.
If you are trying to conceive
The hormonal treatments that ease pain also block conception, so they are paused when conceiving is the goal, and fertility becomes its own job. Laparoscopic surgery to remove deposits improved pregnancy rates in the same trials that showed it eased pain, so it can raise the odds in selected cases.
Assisted reproduction, including IVF, is often the faster route, especially where the disease is more advanced or where time matters. The fixable problems endometriosis causes, blocked or scarred fallopian tubes and disrupted ovulation, respond better the sooner they are treated. An early fertility review, before years of trying, helps most.
The base you steer yourself
These measures do not dissolve deposits already present. They sit beneath the medical and surgical treatments, lowering the odds of the disease over time and making it easier to live with.
Anti-inflammatory eating is the food-first step. In large cohorts followed for over a decade, women eating the most long-chain omega-3 fat from oily fish were 22% less likely to be diagnosed with endometriosis. Those eating the most trans fat, the industrially produced fat in ultra-processed food, were 48% more likely. More dairy and higher vitamin D tracked with lower risk too. These figures are about the chance of developing endometriosis over a decade of follow-up. Health-conscious eaters differ in many other ways, so some of the link may come from those habits. A Mediterranean pattern rich in oily fish, dairy, and whole foods is still a reasonable thing to adopt.
Steady movement you can sustain helps inflammation, mood, and how much the pain takes from your day. Pelvic-floor and pain-focused physiotherapy addresses the tight, guarding muscles and the heightened pain signaling layered on top of the disease. Few trials have tested it in endometriosis specifically, so it counts as sensible pain care that fits alongside the medical treatment.
Heat on the lower abdomen, protected sleep, and tending stress and mood all change how much the pain costs you day to day. Tracking your own cycle and pain lets you and your clinician see the pattern and judge whether a treatment is working.
Across 10 small trials, the six that measured pain found acupuncture eased endometriosis pain by 1.36 points on a 0 to 10 scale. Only one of those trials used a placebo needle, so the result is an early signal that still needs confirming. Acupuncture also lowered CA-125, a blood marker of the disease. In Chinese medicine it targets the wider pattern and does not act on the deposits themselves.
For an ovarian endometrioma, N-acetylcysteine was linked in one observational study to far fewer women going ahead with planned surgery, a signal that needs a randomized trial to confirm.

How it works
Endometriosis affects about 10% of women, and diagnosis often takes years
Endometriosis is womb-like tissue growing outside the womb that feeds on estrogen and causes inflammation, which is why quieting estrogen helps and why the pain follows the cycle.
Endometriosis is defined as endometrial-like tissue outside the uterus, driving a chronic, estrogen-dependent inflammatory process with lesions, adhesions and pain. It affects roughly 10% of reproductive-aged women, is frequently invisible on ultrasound and confirmed at laparoscopy, and carries an average diagnostic delay of several years. Estrogen dependence is the basis for hormonal treatment, and inflammation the basis for the symptom pattern. Measured in: Narrative review of the disease mechanism, epidemiology and management in reproductive-aged women. This is an expert narrative review that frames the disease, not measuring a single treatment effect, so it sets context for the graded treatment claims, not standing as trial evidence itself.
Who this may not transfer to:Endometriosis is a disease of people with a uterus, so all data are in women; there is no male comparison to transfer to.

La curcumina redujo el comportamiento de dolor uterino en ratones al calmar la inflamación nerviosa
En ratones, la curcumina, el componente activo de la cúrcuma, redujo el comportamiento de dolor uterino al calmar la inflamación en los nervios que transmiten la señal del dolor.
En un modelo de ratón de dolor uterino inducido por estrógeno y oxitocina, tanto la curcumina inyectada como la intratecal redujeron las contorsiones y mejoraron el movimiento. El trabajo molecular mostró que la curcumina suprimió la activación de las células gliales y la señalización de MAPK en los ganglios de la raíz dorsal y la médula espinal, y redujo mediadores inflamatorios como IL-6, TNF-alfa, IL-1beta, CCL2 y CXCL1. Measured in: Mouse model of uterine pain induced by estrogen and oxytocin. Se trata de un estudio de mecanismo en ratones, que a menudo usa dosis inyectadas muy por encima de lo que una persona absorbe con cúrcuma oral, por lo que explica una vía plausible, sin demostrar que la curcumina alivie el dolor de la endometriosis en mujeres.

Dienogest cut pelvic pain 12.3 mm more than placebo on a 100 mm scale
A daily progestin tablet called dienogest eased pelvic pain noticeably more than a dummy tablet over three months.
In a 12-week randomized, double-blind trial, dienogest 2 mg daily reduced endometriosis-associated pelvic pain on a 100 mm visual analogue scale by a mean of 27.4 mm, against 15.1 mm with placebo, a difference of 12.3 mm in favor of dienogest (P<0.0001). Rescue analgesic use changed modestly in both arms, and dienogest was generally well tolerated. Measured in: 198 women with laparoscopically confirmed endometriosis-associated pelvic pain, randomized to dienogest 2 mg or placebo for 12 weeks. This measures pain over 12 weeks, not fertility or long-term disease control, and dienogest is a progestin that prevents pregnancy while taken, so it does not suit a woman actively trying to conceive.
Who this may not transfer to:All participants were women with endometriosis; there is no other-sex arm to transfer from.

El dienogest igualó a un agonista de la GnRH en dolor mientras preservaba el hueso, +0.25 % frente a -4.04 % en densidad de columna
Dienogest relieved endometriosis pain about as well as a stronger hormone-suppressing injection, while causing much less bone thinning.
Over 24 weeks, dienogest 2 mg daily and depot leuprolide acetate produced near-identical pain relief (visual analogue scale reduction 47.5 mm vs 46.0 mm), meeting the criterion for equivalence. Dienogest caused fewer hypoestrogenic effects such as hot flashes and far less bone loss: mean lumbar bone density changed by +0.25% with dienogest against -4.04% with leuprolide (P=0.0003). Measured in: 252 women with confirmed endometriosis randomized to dienogest 2 mg daily or depot leuprolide acetate for 24 weeks. Esto muestra que los dos tratamientos son similares para el dolor a lo largo de 24 semanas, no que ninguno lo elimine, y la ventaja ósea importa más con un uso más prolongado; ambos suprimen la ovulación y no son adecuados mientras se intenta concebir.

El dolor siguió aliviándose durante aproximadamente un año con dienogest y se mantuvo 24 semanas después de suspender
Cuando las mujeres siguieron tomando dienogest durante aproximadamente un año, el dolor pélvico siguió aliviándose, y el alivio duró meses después de que dejaron de tomarlo.
En una extensión de etiqueta abierta continuando dienogest 2 mg al día durante hasta 53 semanas, el dolor pélvico bajó progresivamente durante el tratamiento (P < 0.001) y las irregularidades del sangrado se estabilizaron con el tiempo. Entre el subconjunto seguido después de suspender, la reducción del dolor pélvico persistió durante al menos 24 semanas sin tratamiento. Los eventos adversos fueron en general leves o moderados y llevaron a la retirada en el 2.4 %. Measured in: 168 women continuing into an open-label extension of dienogest treatment, with 34 followed during a treatment-free period. Esta es una extensión de etiqueta abierta de un solo brazo sin grupo control, por lo que muestra durabilidad bajo tratamiento continuado, sin demostrar que el fármaco superara a una alternativa a largo plazo.

La cirugía laparoscópica redujo el dolor y elevó las tasas de embarazo en ensayos con 973 mujeres
La cirugía de mínima invasión para eliminar o destruir los depósitos de endometriosis alivió el dolor general y mejoró la probabilidad de embarazo en comparación con simplemente mirar dentro.
Una revisión Cochrane de diez ensayos aleatorizados (973 participantes) encontró evidencia de calidad moderada de que la cirugía laparoscópica para tratar la endometriosis leve y moderada reduce el dolor general y aumenta las tasas de nacido vivo o embarazo en curso en comparación con la laparoscopia diagnóstica sola. Evidencia de baja calidad de un estudio encontró que la escisión y la ablación eran igualmente eficaces para el dolor. Measured in: Ten randomized trials of 973 women with pain or subfertility from endometriosis, mostly comparing laparoscopic ablation or excision with diagnostic laparoscopy. La evidencia cubre la enfermedad de leve a moderada; la enfermedad grave no se estudió bien, el dolor puede regresar con el tiempo, y la revisión encontró datos insuficientes sobre los daños quirúrgicos para juzgar la seguridad.

La vitamina D y el aceite de pescado no aliviaron el dolor más que el placebo en 69 mujeres jóvenes
En mujeres jóvenes con endometriosis, las cápsulas de vitamina D y aceite de pescado aliviaron el dolor aproximadamente tanto como una cápsula placebo.
En el ensayo aleatorizado, doble ciego, SAGE, 69 mujeres jóvenes (de 12 a 25 años) con endometriosis confirmada quirúrgicamente tomaron 2000 UI de vitamina D3, 1000 mg de aceite de pescado o placebo a diario durante 6 meses. El dolor en una escala analógica visual mejoró en el grupo de vitamina D (de 7.0 a 5.5), pero el grupo de placebo mejoró en una cantidad casi idéntica (de 6.0 a 4.4), y ninguno de los grupos con suplemento difirió significativamente del placebo. Measured in: 69 women aged 12 to 25 with surgically confirmed endometriosis and pelvic pain, randomized to vitamin D3, fish oil or placebo for 6 months. El ensayo fue pequeño y la gran mejora con placebo dificulta detectar cualquier efecto real del suplemento, por lo que esto va en contra de confiar en estas cápsulas como tratamiento del dolor por sí solas, sin zanjar su valor para la prevención.

La píldora combinada alivió el dolor menstrual en ensayos con 612 mujeres, con certeza muy baja
La píldora combinada parece aliviar el dolor menstrual de la endometriosis, aunque la evidencia de ensayos detrás de ella es pequeña y débil.
Una revisión Cochrane encontró cinco ensayos (612 mujeres) de la píldora anticonceptiva oral combinada para la endometriosis. Solo tres (404 mujeres) dieron datos analizables. Frente a placebo, la píldora redujo el dolor menstrual autoinformado al final del tratamiento, pero esto descansó en un único ensayo pequeño con intervalos de confianza amplios, y la revisión calificó la certeza como muy baja. Measured in: Five randomized trials of the combined oral contraceptive pill in 612 women with endometriosis, three analyzable. La evidencia es de certeza muy baja y se apoya en un único ensayo pequeño controlado con placebo, por lo que el amplio uso de primera línea de la píldora descansa más en la experiencia clínica y su comodidad que en datos de ensayos sólidos para la endometriosis específicamente.

Un ensayo de 24 mujeres no pudo mostrar si los AINE alivian el dolor de la endometriosis
No hay suficiente evidencia de ensayos para decir cuán bien funcionan los analgésicos antiinflamatorios para el dolor de la endometriosis, aunque muchas mujeres los usan día a día.
Una revisión Cochrane de los AINE para el dolor de la endometriosis solo pudo analizar un pequeño ensayo de 24 mujeres que comparaba el naproxeno con placebo, el cual no mostró un efecto claro sobre el alivio del dolor (razón de probabilidades de 3.27; IC del 95 %: 0.61 a 17.69). La certeza fue muy baja, y la revisión no pudo llegar a un juicio sobre si los AINE alivian el dolor de la endometriosis. Measured in: One analyzable randomized trial of 24 women comparing naproxen with placebo for endometriosis-associated pain. Muy poco se ha probado aquí, por lo que el resultado silencioso refleja una brecha en los estudios, no un fracaso medido; los AINE siguen siendo un primer paso común para el dolor y conllevan sus propios efectos estomacales y renales.

La acupuntura alivió el dolor de la endometriosis 1.36 puntos en una escala de 0 a 10 en pequeños ensayos
En pequeños estudios, la acupuntura alivió el dolor de la endometriosis en más de un punto en una escala de diez puntos y redujo un marcador sanguíneo de la enfermedad.
En diez ensayos, los seis que reportaron dolor mostraron que la acupuntura redujo el dolor relacionado con la endometriosis en una media de 1.36 puntos en una escala de 0 a 10 en comparación con varios controles (IC del 95 %: 1.01 a 1.72; P < 0.0001), y redujo el CA-125 en sangre periférica. Solo un pequeño piloto usó una aguja placebo y evaluó el cegamiento; los tamaños de muestra oscilaron entre 8 y 36 por brazo. Measured in: Ten trials of acupuncture for endometriosis-related pain, with 8 to 36 patients per arm and mostly non-placebo controls. Casi ninguno de los ensayos pudo cegar a los participantes y todos fueron pequeños, por lo que el efecto combinado es una señal temprana alentadora para el dolor, no un resultado asentado, y la acupuntura se usa para el patrón más amplio, no para eliminar los depósitos.

El omega-3 de cadena larga más alto se correspondió con un riesgo un 22 % menor, la grasa trans más alta con un 48 % mayor
Las mujeres que comían más grasa omega-3 de cadena larga de pescado graso tuvieron aproximadamente un 22 % menos de probabilidades de desarrollar endometriosis, y las que comían más grasa trans tuvieron aproximadamente un 48 % más de probabilidades.
En el Nurses' Health Study II (586,153 personas-año, 1199 casos confirmados por laparoscopia), la ingesta total de grasa no se vinculó con la endometriosis, pero las mujeres en el quinto más alto de ingesta de omega-3 de cadena larga tuvieron un 22 % menos de probabilidades de ser diagnosticadas que las del quinto más bajo (IC del 95 %: 0.62 a 0.99; P de tendencia 0.03), mientras que el quinto más alto de ingesta de grasa trans conllevó un riesgo aproximadamente un 48 % más alto que el más bajo. Measured in: Prospective cohort of US women in the Nurses' Health Study II, 1,199 incident laparoscopically confirmed endometriosis cases over 12 years. What could explain it instead: Long-chain omega-3 intake tracks with overall diet quality and health-conscious behavior, so part of the lower risk may reflect the wider dietary pattern, not the fat itself.. Esta es una asociación de riesgo a lo largo de los años medida mediante cuestionario de alimentos en mujeres sin un diagnóstico previo, por lo que habla de reducir la probabilidad de desarrollar la enfermedad, no de tratar una enfermedad ya presente.

Más de 3 raciones de lácteos al día se vincularon a un 18 % menos de riesgo, y una mayor vitamina D a un 24 % menos
Las mujeres que consumían más lácteos y tenían niveles estimados más altos de vitamina D eran algo menos propensas a desarrollar endometriosis.
Entre 70,556 mujeres del Nurses' Health Study II (1385 casos confirmados a lo largo de 14 años), las que consumían más de 3 raciones de lácteos totales al día tenían un 18 % menos de probabilidades de ser diagnosticadas que las que consumían 2 raciones (razón de tasas 0.82, IC del 95 %: 0.71 a 0.95, P de tendencia 0.03). Las mujeres en el quintil más alto de 25-hidroxivitamina D plasmática prevista tenían un 24 % menos de riesgo que las del quintil más bajo (razón de tasas 0.76, IC del 95 %: 0.60 a 0.97, P de tendencia 0.004). Measured in: Prospective cohort of 70,556 US women in the Nurses' Health Study II, 1,385 incident laparoscopically confirmed endometriosis cases.

Ser más activa físicamente se vinculó, como máximo, a una pequeña reducción en la probabilidad de desarrollar endometriosis, más débil de lo que estudios anteriores habían sugerido.
Entre 102,197 mujeres premenopáusicas del Nurses' Health Study II (996,422 personas-año, 2703 casos confirmados), las mujeres más activas (42 o más MET-horas por semana) tuvieron solo una ligera reducción en la incidencia de endometriosis frente a las menos activas (menos de 3 MET-horas), razón de tasas 0.89, tras ajustar por IMC, tabaquismo, paridad, infertilidad y factores menstruales. El informe anterior de una fuerte asociación inversa no se confirmó. Measured in: Prospective cohort of 102,197 premenopausal US women in the Nurses' Health Study II, 2,703 incident laparoscopically confirmed cases. What could explain it instead: Pelvic pain can itself reduce how much a woman exercises, so undiagnosed early disease could lower activity levels, not the reverse, blunting or reversing the apparent link..

Después de la cirugía, la medicina herbal china igualó a un fármaco hormonal en alivio sintomático en 158 mujeres
Después de la cirugía, la medicina herbal china alivió los síntomas aproximadamente igual de bien que un fármaco hormonal y con menos efectos secundarios, en dos pequeños ensayos.
Una revisión Cochrane encontró dos ensayos aleatorizados chinos (158 mujeres). Después de la cirugía laparoscópica, la medicina herbal china dio un alivio sintomático comparable al fármaco gestrinona (RR 1.04; IC del 95 %: 0.91 a 1.18) con menos efectos secundarios reportados. Ningún ensayo comparó la medicina herbal frente a placebo. Measured in: Two Chinese randomized trials of 158 women taking Chinese herbal medicine after laparoscopic surgery for endometriosis. Con solo dos pequeños ensayos y sin comparación con placebo, esta es una señal preliminar; en la medicina china el patrón decide la fórmula, por lo que una mezcla que le conviene a una mujer puede ser errónea para otra, y los productos vendidos directamente al público tienen un historial documentado de adulteración.

Las mujeres que tomaron el económico suplemento N-acetilcisteína para quistes ováricos de endometriosis tuvieron muchas más probabilidades de evitar la cirugía planificada que las mujeres que no lo tomaron.
En un estudio observacional de mujeres con endometriomas ováricos, 24 de las que tomaban N-acetilcisteína cancelaron la laparoscopia programada porque el quiste se redujo o desapareció, o el dolor se alivió, frente a 1 entre las mujeres no tratadas. Se produjeron ocho embarazos en el grupo de N-acetilcisteína y 6 en el grupo no tratado. Los autores informaron que el compuesto fue bien tolerado sin efectos secundarios.

Where the evidence runs thin
In a randomized trial of 69 young women with endometriosis, vitamin D and fish oil capsules eased pain. But a dummy capsule eased it by almost exactly as much, so neither beat placebo. Correcting a measured deficiency is still reasonable on its own terms.
The older claim that exercise strongly protects against endometriosis did not hold up. In a cohort of over 100,000 women the most active had at most a slightly lower risk, a rate ratio of 0.89. Pain itself can keep women from exercising, so the direction of cause is unclear.
Curcumin, the active part of turmeric, calmed uterine pain in mice by damping inflammation in the pain-signaling nerves. It has not been tested in women.
Go Deeper
- Period pain (dysmenorrhea), the cyclical pain the disease drives.
- Fertility and conception, the plan when pregnancy is the goal.
- Pelvic-floor training, for the guarding muscles that layer on pain.

Cautions With Endometriosis
Extra restraintEverything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
The prescribed treatments are monitored
Dienogest, the combined pill, and the GnRH group are prescribed and monitored. All of them suppress ovulation and prevent pregnancy while taken, so they are paused when you are trying to conceive. Do not start or stop a prescribed treatment on your own, that is a decision with your prescriber.
Supplements and products sold for "hormone balance"
Unregulated slimming and "hormone balance" products sold direct to the public have a documented history of adulteration with undeclared drugs, with no clear dose or contents. N-acetylcysteine for an endometrioma rests on a single observational study, with no randomized evidence yet.
Chinese herbs belong with a practitioner
In Chinese medicine the pattern decides the formula, so a mixture that suits one woman can be wrong for the next. Strong blood-moving herbs are avoided in pregnancy and around heavy bleeding. Use a qualified practitioner and a supply you can trace.
Endometriosis is a real, treatable disease. The hormonal treatments and, where needed, surgery work on the estrogen and the deposits. Diet, movement, pelvic-floor work, and tracking your own pattern are yours to manage. Educate yourself, start there, and consult a licensed practitioner about anything that needs weighing.
When to See Someone
Most of living with endometriosis is steady, day-to-day management. These are the signs to seek care about, urgently for the first three:
- Sudden severe one-sided pelvic pain, with faintness, nausea, or a racing heart: can mean a twisted or bleeding ovarian cyst; needs same-day assessment(seek urgent care)
- A positive pregnancy test with pelvic pain, shoulder-tip pain, or bleeding, which needs urgent care to rule out an ectopic pregnancy(seek urgent care)
- Fever, pelvic pain, and unusual discharge together can signal a pelvic infection(seek urgent care)
- Cyclical bleeding from the bowel or bladder, or pain passing stool or urine that tracks with your period: can point to deep disease; needs specialist review
- Pain deep during sex that has been dismissed as normal, a reason to ask for a specialist assessment
- A planned pregnancy not happening after a reasonable time trying, a reason to seek a fertility review early
- Low mood, anxiety, or distress from living with chronic pain: common with endometriosis and worth proper care
Any change to a prescribed treatment is a decision you make with your prescriber. If pregnancy is your goal, the timing of pausing those treatments is planned the same way.
Common Questions
Do I have to have surgery?
Not necessarily. Hormonal treatment is first-line and helps many women without an operation. When pain persists despite it, or when fertility is the goal, laparoscopic excision or ablation is the next step (Duffy, Cochrane 2014).
Will endometriosis affect my chances of getting pregnant?
Yes, it can. Because the treatments that calm pain also block ovulation, they are paused while you try. A fertility review early, well before years pass, gives the best odds (Duffy, Cochrane 2014).
