Age Effects on Fertility - Your Chance of Parenthood

A really important aspect when trying to conceive is the effect of age on fertility. Let's explore the possibilities in this brief article, or watch the video for more details.

This issue is relevant for both women and men as highlighted here.

Knowing the specific issues can help in family planning as people enter committed relationships later in life.

Men's age effects on their Fertility

Yes, age effects on fertility are quite different in men and women.

It appears more 'set' in women who have a defined period around which their fertility starts to reduce.

But what of men?

Your fertility as a man is dependent on several factors and not just age.

And so the fact is that just as women's fertility does decline after a period, so does men's.

Lifestyle choices, overall health and occupation play a part in the changes that happen as a man ages, but generally, fertility is highest in the 20s-30s than in the 50s-60s.

Male Fertility Decline is an actual 'thing' - as men's testes can produce sperm every day - in numbers, we are speaking of anything from 100- 200 million fresh new sperm every day.

While this activity of daily producing sperm does not technically have an 'endpoint', it does reduce with increasing age.

In addition, naturally, the DNA of the sperm produced will be affected by aging so that they may be less active (motile), or more likely to have abnormality.

This affects fertilisation and subsequent pregnancy chances.

Watch the video to learn how age in both women and men can affect a couple's chances of having a baby.

How Women's Age affects Fertility

As a woman, you know that menarche to menopause are the periods during which you are able to bear children.

In a more defined way, a woman can determine how her age affects her fertility - outside of other issues that can reduce it.

Women ovulate, that is, release eggs from each ovary from menarche till menopause.

However unlike men, women are not generating or producing new egges daily.

As a woman, you are already born with all the eggs you will ever have.

We call this your 'ovarian reserve'.

It is from this store that your body releases an egg for fertilisation every month.

But along your monthly cycle, you also lose thousands of eggs every month.

And as women grow older, the quality of DNA in remaining eggs may naturally decline reducing the chance for fertilisation and healthy pregnancy.

So women simply by ageing will experience loss of egg count and egg quality; while men with age will experience loss of sperm quality.

Knowing some of these differences in the sexes can help with understanding
