NAPO - Novel Approach for Oligospermia
The NAPO study is investigating a new treatment for male infertility, focusing on a condition where men have a low sperm count. This medical problem can make it harder for couples to conceive naturally. The study will test a medicine called Prolia (60 mg solution) by comparing it to a saltwater solution (a 'dummy' treatment or placebo). Researchers will measure the concentration of sperm in participants' semen samples after 80 days to see if Prolia makes a difference. They'll also look at other aspects of sperm quality, whether couples get pregnant, and changes in certain hormones. The goal is to explore if Prolia could be a helpful option for men trying to have children.
At a glance
What is this study about?
The NAPO study is all about helping men who are experiencing male infertility, particularly those who have a low sperm count. This condition, sometimes called oligospermia, means that a man's semen contains fewer sperm than is considered normal, which can make it more challenging to get pregnant naturally.
In this study, researchers want to see if a medication called Prolia (specifically a 60 mg injection) could improve a man's sperm count and overall sperm quality. To do this, they will compare the effects of Prolia with a 'dummy' treatment, which is a saltwater solution that looks exactly like the real medicine but has no active ingredients. This comparison helps scientists understand if any changes observed are truly due to Prolia or if they might happen anyway.
The main thing the researchers will be looking at is how much the sperm concentration (the number of sperm cells per millilitre of semen) changes in each group after about 80 days of treatment. They will also be investigating other important factors, such as the overall quality of the sperm (like how well they move and their shape), whether couples become pregnant naturally, and changes in hormone levels that are important for reproduction. Understanding these factors will help determine if Prolia could be a useful treatment option.
Key takeaways
- The NAPO study is testing a new treatment called Prolia for male infertility caused by low sperm count.
- It aims to see if Prolia can increase sperm concentration and improve sperm quality.
- Participants will receive either Prolia or a 'dummy' treatment.
- The study involves providing semen samples, blood tests, and regular medical checks.
- Only men aged 18 and older with male infertility due to low sperm count can participate.
- Participation is voluntary, and you can withdraw at any time.
Who may be eligible?
To take part in the NAPO study, you need to be a male who is at least 18 years old. There's no upper age limit mentioned, so men of any adult age could potentially be eligible.
The study is specifically for men who have been diagnosed with male infertility due to a low sperm count. This means that if you're a man in a couple struggling to conceive and tests have shown your sperm count is lower than normal, you might be able to join.
More detailed checks will be done by the study team to confirm if the study is right for you, based on your specific medical history and other health factors. It's always best to discuss your individual situation with your doctor.
- Are you a male?
- Are you 18 years old or older?
- Have you been diagnosed with male infertility?
- Is your infertility due to a low sperm count?
- Are you able to attend regular study appointments?
- Are you willing to provide semen and blood samples?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
If you decide to take part in the NAPO study, you would be assigned to receive either the study medication (Prolia) or the dummy treatment. These are given as injections. You would provide semen samples at the beginning of the study and again after about 80 days to allow researchers to measure your sperm count and quality.
Throughout the study, you would also have blood tests to check your hormone levels. The study would involve regular check-ups with the study team to monitor your health and any potential changes. Your participation would last for a defined period, and researchers would also be interested in tracking if spontaneous pregnancies occur within 180 days and any potential issues like miscarriages during the total study duration.

Common questions
What is male infertility?
Male infertility means there's a problem with a man's reproductive system that makes it harder for him and his partner to conceive a baby naturally. Often, it's due to issues with sperm.
What does 'low sperm count' mean?
A low sperm count, also called oligospermia, means that a man's semen has fewer sperm than is considered normal, which can impact the chances of getting pregnant.
What is Prolia?
Prolia is a medicine that's being investigated in this study to see if it can help improve sperm count in men with infertility. It's normally used for other medical conditions.
What is a 'dummy treatment' or placebo?
A dummy treatment looks exactly like the real medicine but contains no active ingredients. It's used in studies to compare against the active drug and see if the new medicine truly makes a difference.
Will I know if I'm getting the real medicine or the dummy treatment?
In this type of study, participants usually don't know whether they're receiving the active medicine or the dummy treatment. This helps ensure the results are as fair and accurate as possible.
