In vitro maturation (IVM) of immature oocytes is a promising technique to reduce the costs and avert the side effects of gonadotropin stimulation in in-vitro fertilization (IVF). Cryopreservation of immature oocytes followed by IVM technique can offer advantages, such as to avoid the use of large doses of gonadotropins for multiple follicular growth and induction of ovulation.

Pregabalin is an anti-convulsent drug that is indicated in epilepsy, neuropathic pain and anxiety. This study evaluates its effect on spermatogenesis in male rats through histological and physiological examination of the seminiferous tubules.

Background: Semen preparation techniques were developed to separate motile sperm that are morphologically normal from seminal plasma to optimize successful assisted reproductive technology cycles which seem to be the most effective options in cases of a male factor infertility. Objective: The objective of the present study was to compare between outcomes of two sperm preparation techniques including:
