Right or left ovary - Which one is better?

Abstract

This study tests the hypothesis that there is a different response after gonadotrophin-releasing hormone and human menopausal gonadotrophins (GnRH/HMG) stimulation for in-vitro fertilization (IVF) in patients with either a right or left ovary. A total of 56 cycles in 44 women after left oophorectomy (group A) was compared with 42 cycles in 29 women following right oophorectomy (group B). Tubal disease was the sole cause of infertility in all cases. The two groups were similar in age. There was no difference in total amount or days of HMG required for ovulation induction, peak oestradiol concentrations, number of oocytes retrieved and fertilization rate. The pregnancy rate was identical in the two groups (20.0 and 20.9% respectively). Our results indicate that with GnRH/HMG ovulation induction protocol for IVF there is no predilection of one ovary over the other.
