MALE INFERTILITY

This study tests a new device that sorts sperm without spinning them, which may reduce DNA damage often seen in older men. It involves 378 couples where the male partner is 40 or older and the female partner has at least 5 mature eggs. The goal is to see if this device leads to m…

This study tests a more thorough varicocele surgery that strips away extra veins, compared to the standard method. About 160 infertile men with varicocele will be randomly assigned to one of the two procedures. The goal is to see if the extended stripping reduces the chance of va…

This study tests whether taking royal jelly, a bee product, can improve sperm DNA quality and pregnancy rates in couples with unexplained infertility. Eighty men will take either royal jelly or a placebo daily for three months. Researchers will measure sperm damage, hormone level…

This study tests two different calcium treatments (ionophores) to help eggs fertilize during IVF when previous attempts failed. Researchers will compare which treatment works better and check embryo health. The study involves 20 couples with a history of low fertilization.

This study looks at 40 infertile men with varicoceles (enlarged veins in the scrotum) to see if blood flow measurements in the testicles can predict how well they will respond to surgery. Participants will have ultrasound and blood tests before and three months after a standard m…

This pilot study will follow 90 men aged 18-50 who need heart surgery, some of whom will take the blood thinner warfarin afterward. Researchers will track changes in sperm count, movement, shape, DNA health, and hormone levels over 12 months. The goal is to see if warfarin harms …
