Male infertility

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 early study tests whether two drugs—denosumab and letrozole—can help men with a specific type of infertility (non-obstructive azoospermia) start producing sperm. Sixteen men will take the drugs for about three months, and researchers will check for sperm in their semen or te…

This study compares two medications—gonadotropin and clomiphene citrate—to see which better improves sperm health in men with fertility problems. About 500 men with abnormal sperm analysis will be randomly assigned to one of the drugs. The goal is to measure changes in sperm coun…

This study looks at whether men with a specific gene mutation (TDRD9) get more benefit from L-carnitine, a common supplement, to improve sperm count and movement. About 50 men with low sperm count and motility will take L-carnitine for 3 months. Researchers will compare changes i…

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 is testing a new sperm quality test called SpermQT. It aims to see if the test can predict how likely a couple is to get pregnant with treatments like IUI or IVF. About 1,000 couples will take part, and researchers will track pregnancy outcomes based on the test result…

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 looks at two methods for choosing which embryo to transfer during IVF: the standard way (looking at shape) and a newer way that also tracks how fast the embryo grows. The goal is to see which method leads to more live births. About 520 couples having their first or sec…

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…

This study reviews medical records from about 400 couples where the male partner has a condition called non-obstructive azoospermia (NOA), meaning no sperm is found in the semen. All couples used IVF with a special sperm injection technique. The goal is to see if testing embryos …

This study watches embryos grow using time-lapse cameras and compares their development to genetic test results. Researchers hope to find visual clues that indicate a healthy embryo. 2000 IVF patients are taking part. If a link is found, it could lead to a less invasive way to ch…

This study looks at whether using sperm from a second ejaculate (collected 1-2 hours after the first) can improve fertilization and embryo quality in ICSI, a type of IVF. Researchers will compare sperm quality and pregnancy outcomes between first and second ejaculates in 108 coup…

This study is creating a biobank—a collection of blood samples and health data—to help researchers better understand gynecological disorders, infertility in men and women, and pregnancy-related conditions. Up to 3,000 participants will provide samples at San Raffaele Hospital in …
