Male Fertility also Declines with Age


There’s a common misconception that male fertility is constant from birth to old age. Nothing could be further from reality. Men suffer from a similar decline in fertility as much as their women counterparts.

The dual age-related fertility decline is a natural phenomenon. Thus the belief that women are the only ones who suffer this should be thwarted.



The decline in male fertility begins in the late 30s, and gets more pronounced from the 40s. The overall sperm quality decreases as age advances. Older men will increasingly become incapable of fathering more children, or just contribute to age-related miscarriages and fetal abnormalities.

Men should make decisions in matters of reproduction early enough, balancing this with other competing interests like careers and personal development. Your reproductive plans must take into account your current age.

Awareness of fertility decline must be coupled with a lifestyle that maintains optimal sperm quality. Smoking, chewing miraa and use of other recreational drugs are all very toxic to sperm quality. It doesn’t end there.

Sedentary lifestyles leading to obesity and other illnesses like diabetes also contribute to declining fertility potential. You want to keep yourself in optimal health, and avoid preventable conditions that may accelerate the decline in your reproductive potential.

But we are living in an age where even the best laid plans are often futile. So what if you get caught up with the humdrum of competing interests, and have to push back your plans for raising a family to the later decades?


Just like for women, men also have the option of fertility preservation.

You could choose to freeze your sperms as a backup for later use, when conditions for starting a family are more favorable. Better still, you could freeze fertilised eggs (called embryos), if already in a stable relationship but not ready yet to start a family. Frozen sperms or embryos maintain their quality till eventual use. But there are costs and ethical dilemmas involved in such matters that you must be willing to contend with.

Remember even advances in assisted conception techniques cannot fully compensate for age-related fertility decline. Aim to seek help early if conception does not occur within six months whilst in the advanced age group. Don’t send your female partner alone to a fertility clinic. You should always accompany her as you may be the one with a problem.
