Obtaining viable and transferable embryos is the key to the success of in vitro fertilization (IVF). However, in clinical practice, some couples exhibit repeated early embryonic arrest despite having seemingly "normal" sperm and oocytes. Clinicians generally attribute this issue to female rather than male factors, especially when sperm is diagnosed as normal by clinical standards. To date, there have been no reports of male genetic factors leading to early embryonic development failure.

Unlike fulvestrant, a traditional SERD that requires intramuscular injection, elacestrant is an oral preparation taken once a day. It spares patients from frequent hospital visits for injections or infusions, greatly improving the convenience of treatment and quality of life, and making "home-based treatment" a reality.

Assisted reproduction is a road full of unknowns. For patients, nothing is more needed than a professional team, reliable technology, and trust between people. At the Reproductive Medicine Center of Jiahui Health, the long-term cooperation between the clinical and embryo laboratory teams led by Professor Sun Xiaoxi and Director Sun Yijuan is the source of this confidence – precise clinical decision-making, meticulous laboratory execution, mutual trust, and joint face of every complex case.
