Azoospermia means no sperm are found in the semen. It affects about 1 in 100 men and around 1 in 10 men with infertility. It usually causes no symptoms and doesn't affect erections or ejaculation. It can be a shock to hear, but many men with azoospermia can still father biological children — through treatment of the cause, or by retrieving sperm directly from the testes for IVF.
One semen test showing no sperm isn't enough — the sample should be repeated, collected after 2–7 days without ejaculation, and the laboratory should spin it down (centrifuge) to look for even a few sperm. Finding a small number (cryptozoospermia) changes the options. See also our page on low sperm count.
| Obstructive | Non-obstructive | |
|---|---|---|
| What happens | Sperm are made normally but a blockage stops them reaching the semen | The testes make very few or no sperm |
| Common causes | Vasectomy; past infection (including TB and STIs); injury or surgery in the groin; being born without the vas deferens (linked to cystic fibrosis genes) | Genetic conditions (Klinefelter syndrome, Y-chromosome changes); undescended testes; mumps orchitis; chemotherapy or radiotherapy; hormone problems; anabolic steroid use |
| Clues | Normal-sized testes; normal FSH hormone | Often smaller, softer testes; raised FSH |
| Outlook | Sperm can almost always be retrieved; some blockages can be repaired | Sperm can be found in about half of men with micro-TESE surgery |
Ayurveda describes absence of semen or sperm within Shukra kshaya and Shukra dushti, and distinguishes causes from birth (bijadosha) and from obstruction or depletion. Vajikarana therapy uses nourishment, rest and rejuvenating herbs. Ayurveda cannot overcome a blockage, a genetic cause, or the absence of sperm-producing cells — these need modern treatment — but supportive care may help general health while investigations and treatment proceed.
Infertility is a shared medical issue, not a failing of either partner, and it carries real emotional strain — particularly with family pressure. Counselling for the couple, and talking with others who have been through it, help. For confidential support, call Tele-MANAS on 14416.
