WORLD OF REPRODUCTIVE BIOLOGY: Progesterone and Endocannabinoid Interaction Alters Sperm Activation

A recent study in Science finds that α/β-hydrolase domain-containing protein 2 (ABHD2) is a novel nongenomic progesterone receptor that holds the CatSper cation channel open while progesterone elevates sperm cytoplasmic calcium ion (Ca) levels and triggers sperm hyperactive motility. ABHD2 functions as a lipid hydrolase, breaking down arachidonoylglycerols (2-AG/1AG)—endocannabinoid components ...

Sperm Vacuoles and Reproductive Outcome

It is estimated that the male factor contributes to half of the infertility in couples attending for assisted reproductive techniques (ART). Therefore the semen analysis remains the starting point to evaluate main causes of infertility and in case of oligospermic semen the assessment of sperm morphology may help to choose the best spermatozoon to use for the intracytoplasmic sperm injection (IC...
