Endometriosis can affect fertility through several interconnected mechanisms. It does not mean that conception is impossible, and many women with endometriosis do conceive naturally. However, the condition may make the journey more complex for some, depending on its extent, location and the individual's wider health picture.
Inflammation is one of the most significant factors. Chronic inflammation associated with endometriosis can affect egg quality, the fallopian tubes and the environment in which an embryo needs to implant. Scar tissue and adhesions may also alter pelvic anatomy in ways that affect egg release or the movement of sperm.
Hormonal imbalance is another consideration. Because endometriosis is oestrogen-dependent, it can disrupt the hormonal signals that regulate ovulation and cycle regularity, which in turn affects the timing and likelihood of conception.
In simple terms, endometriosis may affect fertility by driving inflammation, altering pelvic anatomy through scarring and adhesions, and disrupting the hormone signals needed for ovulation and implantation. Supporting inflammation, hormone balance and the implantation environment can be an important part of preparing for pregnancy.
Endometriosis can look different from person to person, so the most helpful fertility support plan will depend on your symptoms, cycle pattern, health history, nutrition, lifestyle and any treatment you are already undergoing. Personalised guidance is often the best starting point.
