Based on this background, some studies investigated if ovarian endometrioma influenced the frequency of ovulation in the affected ovary. Initial studies suggested that ovulation occurs less frequently in ovaries with endometriomas. However, more recently, a prospective Italian study including 244 women with unilateral endometriomas demonstrated that ovulation is not affected by the presence of endometrioma and that the number and the size of endometriomas do not influence ovulation. Endometriosis may impair fertility through multiple pathways, including peritoneal inflammation, endocrine derangements that reduce oocyte competence, and decreased endometrial receptivity; however, it does not seem to affect spontaneous ovulation significantly.\nAccess this chapter\nTax calculation will be finalised at checkout\nPurchases are for personal use only\nSimilar content being viewed by others\nReferences\nMaggiore ULR, Gupta JK, Ferrero S.
