low ovarian reserve according to Bologna criteria and carriers of androgen receptor polymorphism

Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy, Efficacy

To determine whether pretreatment with transdermal testosterone increases the number of cumulus-oocyte complexes (COCs) obtained after ovarian stimulation by more than 1.5 in patients with low ovarian reserve and androgen receptor polymorphism undergoing intracytoplasmic sperm injection (ICSI).

Secondary objectives 1

  1. To assess whether there are differences between the two groups in terms of: number of mature (MII) oocytes, fertilization rate, blastocyst formation rate (blastocysts/MII), number of follicles >14 mm on the day of GnRH agonist administration to trigger final oocyte maturation, duration of stimulation, gonadotropin consumption, cycle cancellation rate, free androgen index value and gestation rate.
