Oocyte donation is offered to patients with premature ovarian failure to achieve pregnancy when no other assisted reproductive technology is possible. Some clinical and biological factors have been identified for influencing the outcome of oocyte donation cycles. Embryo implantation depends on embryo quality, method for the embryo transfer, and endometrial differentiation. In our center, the oocyte recipients receive for the endometrial preparatory cycle the same treatment that for the patients undergoing frozen embryos transfers, with good clinical pregnancy rates, about 35% per transfer. Estrogen and progesterone supplementation with GnRH agonist down regulation are used in synchronized protocols or for frozen embryos transfers. The synchronization between recipient's endometrium and donor's ovarian stimulation is very restrictive. Nowadays, the oocytes vitrification lithens the oocyte donation process: the endometrial preparation has a limited duration and is well controlled, and embryos that are transferred are all fresh embryos.

Purpose: This survey aimed to assess the public's knowledge and opinions on oocyte donation (OD) among a large, unselected cohort of young Belgian women, and to explore aspects that could be enhanced to promote future OD programs.
Methods: We conducted a quantitative, epidemiological, cross-sectional web-based survey from February 2023 to April 2023. A private questionnaire was distributed to young women (21-30 years) living in Belgium via a digital link.

Objectives: The Bioethics Law of August 2nd, 2021 established access to origins for people conceived by gamete donation. Two years after the implementation of this disposition, what is the proportion of former gamete donors informed about access to origins, and what is their position on this matter? What could be the potential repercussions of this new law on them?
Methods: Retrospective single-center cohort study using questionnaires.
Results: When former gamete donors were asked about access to origins, only 53% of oocytes donors and 71% of sperm donors were aware of this measure.

Purpose: To compare the efficacy of modified natural cycle (mNC) preparation versus hormone replacement therapy (HRT) for endometrial preparation in recipients of donated oocytes, specifically focusing on pregnancy rates in women of advanced maternal age.
Methods: Retrospective multicenter analysis conducted between 2021 and 2024. It includes 220 cycles of fresh single blastocyst transfers resulting from oocyte donation.

In this article I explore the dual impact of framing egg donation and surrogacy as work in Ukraine's fertility market. Egg donors, surrogates, and ART professionals use the labor narrative to legitimize these practices, albeit with differing aims. Women emphasize their economic role as worker-mothers, demanding fair treatment and recognition, while clinics employ the framework to market surrogates and donors and hold them accountable for outcomes.
