Accidental exposure to daily long-acting gonadotrophin-releasing hormone analogue administration and pregnancy in an in-vitro fertilization cycle

A case of successful pregnancy in an in-vitro fertilization cycle, in spite of an accidental exposure to daily long-acting gonadotrophin-releasing hormone analogue administration, is reported. The patient underwent two intracytoplasmic sperm injection cycles with thawed epididymal spermatozoa, in which, due to a pharmacist's mistake, ovarian stimulation was carried out by a combination of long-acting gonadotrophin-releasing hormone agonist (leuprolide depot) and gonadotrophins. A successful singleton pregnancy was achieved after intrauterine embryo transfer with the birth of a healthy boy after 38 weeks. We describe the circumstances and results of this clinical case, as well as reviewing the literature.
