Spermatogenic failure

This study aimed to see if the drug clomiphene citrate could help men with a condition called non-obstructive azoospermia, where the body produces little to no sperm. The plan was to give the drug or a placebo for nine months, then check if sperm could be found in the semen or th…

This study tests two treatments—isotretinoin (an acne medication) and hCG (a hormone)—to see if they can help men with low or no sperm count produce moving sperm. About 100 men aged 19 to 50 will take one of the drugs for three months. The goal is to find new options for male inf…

This study compares a new microfluidic device, SwimCount Harvester, to standard sperm preparation methods in couples undergoing IVF with genetic testing (PGT-A). About 1,600 couples will be randomly assigned to one of the two methods. The goal is to see if the device leads to mor…

This experimental study tests whether frozen-thawed testis tissue, when grafted under the skin, can produce sperm in men with infertility. Five men will receive their own stored tissue. The goal is to see if viable sperm can be retrieved, potentially offering a future fertility o…

This study tests a non-surgical method to collect sperm from men with a condition called azoospermia, where no sperm is found in the semen. Using ultrasound guidance, doctors flush and suction fluid from a part of the testicle to retrieve sperm. If successful, this could help inf…

This study tests whether adding a substance called cpFT to the liquid used to grow eggs and embryos can increase the number of live births in women under 37 who are having a type of IVF called ICSI. About 366 couples took part. The goal is to see if this simple change can improve…

This study records 30-second videos of embryos from 1,000 IVF patients and uses artificial intelligence to analyze their movement patterns. The goal is to see if these patterns can predict whether an embryo will lead to a successful pregnancy. Participants receive standard care a…
