From the Guidelines
Approximately 50% of patients with endometriosis experience infertility, as stated in the most recent study 1. This is a significant concern for women with endometriosis, as it can impact their quality of life and ability to conceive. The severity of infertility often correlates with the stage of endometriosis, with more advanced disease typically associated with higher infertility rates. Endometriosis causes infertility through several mechanisms:
- Distorted pelvic anatomy from adhesions and scarring
- Altered immune function that may interfere with embryo implantation
- Impaired egg quality
- Compromised fallopian tube function
- Hormonal imbalances affecting ovulation Treatment options for endometriosis-related infertility include surgical removal of endometriotic lesions, which can improve natural conception rates, and assisted reproductive technologies like intrauterine insemination (IUI) or in vitro fertilization (IVF) 1. The approach depends on the woman's age, endometriosis severity, duration of infertility, and other fertility factors. Despite these challenges, many women with endometriosis can achieve pregnancy with appropriate medical intervention. It is essential to note that the diagnosis of endometriosis is challenging, and imaging studies, such as expanded protocol transvaginal ultrasound (TVUS) and MRI, can help inform patient decision making and surgical planning 1. However, the primary focus should be on addressing the infertility concerns and providing individualized treatment options to improve outcomes.
From the Research
Infertility Percentage for Women with Endometriosis
- The prevalence of endometriosis in the general population is estimated to be around 5-10% 2, 3, 4.
- Studies suggest that up to 50% of women with endometriosis may experience infertility 2, 3, 5.
- The probability of patients with infertility having endometriosis is reported to be around 30-50% 3, 5, 4.
- The relationship between endometriosis and infertility is complex and not fully understood, with multiple mechanisms involved 2, 4.
- Treatment options for endometriosis-associated infertility include surgery, hormonal medications, and assisted reproductive technology 3, 6.
Mechanisms of Infertility in Endometriosis
- Advanced cases of endometriosis with distorted pelvic anatomy may lead to infertility due to mechanical factors 4.
- Early-stage endometriosis may be associated with endocrine dysfunctions, such as luteal phase defect and luteinized unruptured follicle syndrome 4.
- Alterations in the local pelvic immune environment have also been proposed as a potential mechanism of infertility in endometriosis 4.
Treatment and Management
- Surgical treatment of endometriosis may improve cycle fecundity and increase the chances of conception 3, 6.
- Hormonal medications, such as combined oral contraceptives and gonadotropin-releasing hormone agonists, may be used to treat endometriosis-related pain and infertility 6.
- Assisted reproductive technology, such as in vitro fertilization, may be necessary for women with endometriosis-associated infertility who do not respond to other treatments 3, 6.
