Abstract

This article aims at reviewing the literature in order to provide a summary of the actual knowledge about the clinical factors of the oocyte recipient (other than those affecting the morphology of the uterine cavity) influencing the outcome of oocyte donation cycles. Recipient age, from 45 years onwards, is clearly associated with a poorer outcome in oocyte donation cycles as well as the presence of a hydrosalpinx. The negative impact of smoking has recently been confirmed. The exact influence of a high body mass index is under examination but it is likely that it is associated with a lower ongoing pregnancy rate. Endometriosis does not have a negative impact when standard endometrial priming protocols are used in oocyte donation. During endometrial priming, serum estradiol levels and endometrial thickness, if >5 mm, does not influence negatively the outcome; however duration of estrogen treatment of more than 7 weeks is associated with a diminished pregnancy and implantation rate.
