Most of the times people say age is a number only, but in certain biological functions Age matters. “Old” “young” are comparative numbers, let’s talk more precise at what age people should become parents and why? This is the biological phenomenon; you cannot go on your whims and fancies It's a biological fact that as women and men age, their potential to have children decreases, although the exact time when this starts to happen can vary among individuals. We all know someone who had a healthy baby in their late 30s or early 40s. But of all people who try for a baby at a later age, many will not have the baby they hoped to have.
The combination of both partners' ages determines the likelihood of pregnancy and their child’s heath, intelligence, and longevity. Younger women and men have more and healthier eggs and sperm than older women and men. However, a woman’s age is the most important factor affecting her fertility and her chance of having a baby.
One can find hundred reasons for not to have baby now but their “biology” would not wait.
For individuals and couples there can be many reasons why life gets in the way of starting a family. Not having a partner, career, finances, housing, travel, not feeling ready, whatever the reason, many find that it’s just not the right time to have a baby.
Sometimes people find themselves trying to get pregnant later in life, when it can be a lot more difficult.
For women, the easiest time to get pregnant is before the age of 30. As women get older, it takes longer to conceive and the chance of having a baby decreases.
Why female is more important
The telomeres of the early produced eggs are very long but become shortened as more are made. So a woman has a finite number of eggs, some with long telomeres and some with shorter telomeres. After birth, when the female reaches puberty, these long-telomere egg cells are the first to be released by the ovaries, and the first to become potential embryos. Thus, it will be advisable to have children as near to puberty as possible; this will increase the chances for inheriting chances of long telomeres. It also explains why having children later in life increases the chance for birth defects or miscarriages.
These are little protective caps at the ends of the DNA molecules that make up our chromosomes. Their job is to stop the ends of chromosomes from fraying or sticking to each other, much like the plastic tips on the ends of shoelaces.
About Sperm
Unlike fixed number of eggs in females at the time of birth, the germ cells in male divide in the tubules of the testicles and are constantly producing new sperm. Men produce sperm cells throughout their whole life, The full process takes about 64 days.
Sperm in the semen
During spermatogenesis, the testicles make several million sperm per day — about 1,500 per second. By the end of a full sperm production cycle, you can regenerate up. The germ cells divide to 8 billion sperm. Although, it takes the average sperm about 74 days to fully mature; the body makes millions of sperm each day. Sperm in the male body last up to 74 days, subsequently reducing the fertilizing capacity of semen. If they are not ejaculated, they die and reabsorb in the body. Frequent ejaculation will not cause the body to run out. Men with healthy, normal sperm counts should not worry about the effects of regular ejaculation. (The author has his own study and views)
