Fertility
Does endometriosis affect egg quality or implantation?
The short answer
Endometriosis can affect both egg quality and implantation. In the ovaries, especially with ovarian endometriomas, inflammation may affect how eggs mature, while changes in the uterine lining may make it less receptive to implantation.
Endometriosis can affect both egg quality and implantation. Its effects on fertility aren’t limited to one step. In the ovaries, endometriosis (especially ovarian endometriomas and the inflammation they create) may interfere with ovulation and the environment where eggs mature. This can contribute to lower oocyte competence for some patients.
Endometriosis can also change the uterine lining in ways that may reduce implantation receptivity, even when tubes look open and imaging seems normal. It may also disrupt pelvic anatomy and fallopian tube function through inflammation, adhesions, and altered contractions, affecting pickup and transport of the egg or embryo. If you’re trying to make sense of your own situation, our team can help connect your symptoms, imaging, and fertility history to the most likely mechanisms and discuss options like excision surgery and coordinated fertility planning.

Questions people ask next
All fertility questionsCan endometriosis cause recurrent implantation failure in IVF?
Yes, endometriosis can be one contributing factor in recurrent implantation failure for some IVF patients. It may affect how the uterine lining functions, but implantation failure is rarely due to one diagnosis, and many people with endometriosis still have successful IVF outcomes.
Can endometriomas lower AMH without affecting egg quality?
Yes, an endometrioma can be linked with lower AMH without automatically meaning poor egg quality. AMH mainly reflects how many small follicles are available, not egg quality; age and follicle counts in each ovary help put the result in context.
Do endometriosis and adenomyosis affect fertility?
Endometriosis and adenomyosis can both make it harder to conceive, though the reasons can differ from person to person. They may affect fertility through inflammation, scarring, ovarian involvement, or uterine changes that can interfere with implantation and pregnancy.
Can endometriosis surgery affect fertility?
Yes, endometriosis surgery can affect fertility in both positive and negative ways, depending on where the disease is and what surgery involves. Removing disease can improve the chances of conception, but surgery on the ovaries can reduce ovarian reserve.
