IVF stimulation protocols and outcomes in women with endometriosis

Endometriosis is a complex medical condition with a high prevalence in women of reproductive age. Fertility is compromised in patients with endometriosis, and success in IVF treatments has been a challenge leading to evaluation of different stimulation protocols. The long-standing debate between GnRH agonist long protocols and short GnRH antagonist protocols is being resolved in favor of the latter, since in addition to presenting equivalent results with respect to the traditional option, they have the additional benefit of safety. The good results derived from vitrification techniques have led to the development of new stimulation strategies, such as progestin-primed ovarian stimulation (PPOS), with a greater degree of approval among patients. None of the stimulation protocols currently applied in women with endometriosis has been shown to be superior, so early intervention with an Assisted Reproduction treatment, regardless of the chosen protocol, can provide these women with good chances of motherhood. Women with endometrioma should be counseled for fertility preservation before planned ovarian endometrioma excision. The number of cryopreserved oocytes or embryos can be increased by repeated cycles.
