New hormone treatment for men with no sperm
Part of Kidney & urinary clinical trials.
This study tests a new medication called leflutrozole for men with a condition where no sperm is produced (azoospermia). The drug may help increase hormone levels that support sperm production, potentially improving fertility.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be a man between 18 and 55 years old.
- You need to have been diagnosed with azoospermia (no sperm in semen) confirmed by at least two separate semen samples.
- Your semen sample must be at least 1 mL in volume, and there must be no obvious blockage in your reproductive system.
- You need to have a detectable level of certain hormones (AMH or inhibin B) in your blood, and your testosterone must be below a certain level.
- You cannot have Klinefelter syndrome or other major genetic conditions, and you must not be currently using steroids.

This study tests a new oral medication (PKB171) compared to a placebo for couples who have mild male infertility and have not tried IVF/ICSI before. The goal is to see if PKB171 can help them conceive naturally.
This trial tests a new drug called Leflutrozole to see if it can improve testicular function in men with low testosterone and low sperm count. The goal is to help increase natural hormone levels and sperm production.
This study tests two medicines—isotretinoin and human chorionic gonadotropin (hCG)—to see if they can improve sperm production in men with low sperm counts or no sperm due to certain causes. It might help if you haven't responded to other treatments before.
This trial studies whether gonadotropin therapy (hormones that stimulate sperm production) can help men with low testosterone and very low sperm count. It may be useful if you have been diagnosed with non-obstructive azoospermia and have not had recent surgery or hormone treatment.
This study tests whether a weight-loss injection or a healthy lifestyle program can improve sperm quality and fertility in obese men with low sperm health. You would be randomly assigned to one of the two groups, and the study will track your progress over time.
This study tests an experimental medicine called MediReg® for men with severe infertility who have not been able to conceive. It aims to see if the drug is safe and can improve sperm quality, possibly offering a new option for men who have not had success with other treatments.
