This case illustrates the possibility of obtaining oocytes that fertilize
and cleave normally after the administration of a second ovulatory dose of
human chorionic gonadotrophin (HCG) in a case of 'empty follicle syndrome'.
The present patient underwent ovarian stimulation with
gonadotrophin-releasing hormone analogue (GnRHa)/menotropin for
intracytoplasmic sperm injection (ICSI). After the failure of the first
oocyte retrieval, a second dose of HCG was administered to trigger
ovulation. A total of 13 oocytes was retrieved during the second procedure
and 11 good quality embryos were obtained (fertilization and cleavage rates
of 92 and 91% respectively). No pregnancy was achieved after the
replacement of three embryos. In a subsequent cycle stimulated with
clomiphene citrate, three frozen- thawed embryos were replaced and a twin
pregnancy was achieved. The patient delivered two healthy babies at term.
