Successful pregnancy and delivery in a female with pituitary stalk interruption syndrome following in vitro fertilization and embryo transfer: A case report and literature review.

Pituitary stalk interruption syndrome (PSIS) in female patients is mainly characterized by short stature, primary amenorrhea, absent or incomplete sexual maturation, and infertility. Successful pregnancies among these patients are rare. In this report, we describe a successful pregnancy and delivery in a 28-year-old Chinese woman with PSIS following in vitro fertilization and embryo transfer. The patient exhibited typical symptoms, including multiple pituitary hormone deficiency, typical triad signs in magnetic resonance imaging (MRI), undetectable serum gonadotropins and estradiol levels, and invisible antral follicles in both ovaries. During the first attempted controlled ovarian hyperstimulation cycle, 14 oocytes were retrieved and six embryos were acquired. Artificial endometrial preparation and frozen-thawed embryo transfer were performed, resulting in a clinical pregnancy after the transfer of a day 5 blastocyst. The patient was closely monitored throughout the pregnancy and multiple hormone dosages were modulated accordingly. She delivered a healthy boy by elective cesarean section, and the newborn developed normally during a 1-year follow-up period. This is the first report of a successful live birth in a woman with PSIS achieved through in vitro fertilization and frozen-thawed embryo transfer. A literature review on this topic is also presented.
