How Are Progesterone Resistance and Endometriosis Connected?
Endometriosis occurs when normal endometrial cells, which typically line the uterus, grow outside of it. These abnormal growths commonly develop in the pelvis but can extend to areas around the ovaries, fallopian tubes, and nearby organs. Endometriosis is a leading cause of unexplained infertility and often goes undiagnosed for extended periods. Here’s an exploration of the link between endometriosis and progesterone resistance:
The relationship between progesterone resistance and endometriosis can significantly impact fertility, often leading to challenges in conceiving. Women experiencing these hormonal imbalances may benefit from a thorough evaluation of their reproductive health.

Progesterone Resistance Definition and Causes
Progesterone, a steroid hormone associated with pregnancy, is synthesized by the ovaries, adrenal glands, and placenta. Its effects are mediated by progesterone receptors. These receptors bind to progesterone, regulating the expression of genes and signaling pathways responsive to the hormone. Progesterone resistance occurs when these receptors become suppressed or altered. This can lead to an unresponsive endometrium and disrupted progesterone signaling pathways.
The resistance can impact hormone function and gene expression, contributing to symptoms such as chronic pelvic pain, ovulatory problems, inflammatory conditions, infertility, and potentially cancer. Progesterone resistance can stem from various factors, including altered receptor function, chronic inflammation, and prenatal conditions. Women with endometriosis often exhibit signs of progesterone resistance.
Endometriosis Definition and Causes
Eutopic endometrial tissue grows naturally within the uterus and sheds during menstruation. When this tissue grows outside the uterus, it forms ectopic growths characteristic of endometriosis. These abnormal growths may obstruct fertilization by preventing sperm from reaching the egg, leading to infertility. Ectopic endometrial growths may cause inflammation, heavy menstrual bleeding, and other complications.
Endometriosis can sometimes be asymptomatic, with no apparent pain, inflammation, or ovulatory disturbances. Despite the lack of symptoms, asymptomatic endometriosis poses challenges in diagnosis and is a common underlying cause of unexplained infertility and unsuccessful IVF treatments.
To assess for endometriosis and progesterone resistance markers, fertility specialists may recommend tests such as BCL-6 and CD 138. A positive BCL-6 test strongly suggests the presence of endometriosis, prompting further investigation. In clinical settings, laparoscopy and hysterectomy are utilized by fertility clinics to diagnose and surgically remove ectopic endometrial tissues, aiming to improve fertility outcomes.
Progesterone Resistance and Endometriosis Connection
Women with ectopic endometrium often exhibit reduced expression of progesterone receptors. Fertility specialists commonly prescribe pregnancy medications that include exogenous progesterone treatments. These medications aim to elevate progesterone levels when low progesterone is a contributing factor to infertility or recurrent pregnancy loss. Despite these efforts, treatments such as progestin frequently prove ineffective in many women with endometriosis. This lack of response often leads doctors to conclude that endometriosis itself suppresses the expression and function of progesterone receptors.
Progesterone resistance is a recognized phenomenon among women with endometriotic lesions. Endometriosis impedes the upregulation of enzymes that help with converting estradiol to estrone during progesterone therapy. The condition suppresses progesterone receptor levels in affected tissues. These diminished and dysregulated levels of progesterone receptors can lead to altered gene transcription and disrupted signaling pathways, even when progesterone levels are within the normal range.
Treating Endometriosis and Progesterone Resistance
Women diagnosed with endometriosis often exhibit progesterone resistance, a condition that may be alleviated through effective treatment of the endometriosis itself. Endometriosis represents one of several potential causes of progesterone resistance. If you are facing recurrent pregnancy loss, unexplained infertility, or repeated failure with IVF treatments, it is advisable to undergo testing to determine if endometriosis may be a contributing factor. A BCL-6 test can be particularly useful in identifying endometriosis as an underlying cause of fertility challenges.
A positive BCL-6 test result should prompt further diagnostic evaluations and consideration of surgical options to remove abnormal tissues associated with endometriosis. CD 138 tests can assess markers indicative of progesterone resistance. Treatment targeted at addressing endometriosis often leads to improvement in progesterone resistance linked to this condition. Resistance may arise from other causes or a combination of factors involving endometriosis and additional underlying issues. A thorough evaluation and personalized treatment plan are needed before attempting to conceive again.

Endometriosis and progesterone resistance are known contributors to infertility. If you’re unable to conceive despite being in your reproductive years, consult with a healthcare provider to identify and address the root cause. Undergoing BCL-6 and CD 138 tests can help assess whether endometriosis and progesterone resistance may be factors in your unexplained infertility.
