The Detection of CatSper1 and CatSper3 Expression in Men with Normozoospermia and Asthenoteratozoospermia and Its Association with Sperm Parameters, Fertilization Rate, Embryo Quality.

CatSper affects sperm function and male fertilization capacity markers, including sperm motility and egg penetration. The study has aimed to evaluate the mRNA expression of CatSper1, and CatSper3 in the spermatozoa of men with normozoospermia and Asthenoteratozoospermia, and to assess the correlation between genes expression and sperm parameters, fertilization rate, and embryo quality in intracytoplasmic sperm injection (ICSI). Reverse transcription-polymerase chain reaction was utilized to evaluate the mRNA expression of CatSper1 and CatSper3 in sperm in two patient groups: Normozoospermia (NOR; n = 32), and Asthenoteratozoospermia (AT; n = 22).

The effect of cult-active medium on pregnancy outcomes after intracytoplasmic sperm injection in azoospermic men: A case-control study.

Background: Failed oocyte activation following intracytoplasmic sperm injection (ICSI) as a result of calcium deficiency is a major challenge.

Objective: We compared the effect of cult-active medium (CAM) on ICSI outcomes in obstructive azoospermia cases.

Materials And Methods: The present study was conducted with 152 ICSI cases, classified into CAM and control groups.
