Male Reproductive Age and Fertility – Iswarya Fertility Centre
27 Oct 2025
Understanding Male Reproductive Age
A man’s reproductive age starts at puberty, usually between 12 and 16 years old, when sperm production begins. Unlike women, who are born with a fixed number of eggs, men produce new sperm throughout their lives. This means that, biologically, men can father children well into older age.
However, the ability to father children is not equal at all ages. Peak male fertility is generally in the early twenties to early thirties, with a gradual decline starting after age 35 or 40.
How Age Affects Male Fertility
Sperm quality and quantity: After age 40, both sperm count and quality (motility and shape) start to decline. This can make it harder to fertilize an egg.
DNA fragmentation: Sperm from older men is more likely to have DNA damage, which can affect embryo development and increase the risk of miscarriage.
Time to conception: Couples where the male partner is over 40 often take longer to achieve pregnancy because sperm mobility is lower.
Risk of complex pregnancies: Babies fathered by older men may have a higher risk of some genetic conditions and disorders, such as autism and schizophrenia.
Can Older Men Still Have Children?
Yes, many men remain fertile into their 50s and beyond. However, conception may take longer, and there are increased risks. By age 45, the chances of conception per month fall significantly compared to a man under 30.
Lifestyle and Health Factors
Fertility is also affected by health and lifestyle choices. Factors like obesity, smoking, excessive alcohol, untreated medical conditions, and exposure to environmental toxins can reduce sperm health at any age. Maintaining a healthy lifestyle boosts both general health and fertility.
When Should Men Seek Fertility Advice?
If a couple has been trying to conceive for over a year without success (or six months if the female partner is over 35), it’s a good idea for both partners to get checked. At Iswarya Fertility Centre, both men and women receive a thorough assessment to find any barriers to conception and discuss treatment options.
Diagnostic Tests for Men
At Iswarya Fertility Centre, the fertility team may recommend,
Semen analysis: To check sperm count, motility, and shape.
Hormonal tests: To look for hormone imbalances that affect sperm production.
Genetic testing: If hereditary conditions are suspected.
Ultrasound: To check for structural problems in the reproductive organs.
Treatment Options at Iswarya Fertility Centre
Most men with mild to moderate fertility issues benefit from:
Lifestyle changes: Quitting smoking, limiting alcohol, exercising, maintaining a healthy weight.
Medication: For hormonal imbalances or infections affecting fertility.
Assisted reproductive techniques: Methods like IVF or ICSI (where a single sperm is injected into an egg) can overcome low sperm counts or sperm quality issues.
Surgical treatments: For blockages or varicoceles that impact sperm flow.
