#sperm quality

Do you know that couple? The ones who can’t quite get there in making a baby no matter what. Maybe you are one of them. Maybe not. Regardless, a team of scientists is warning humans could become extinct very soon, real soon, much sooner than anyone thought. From Mount Sinai, epidemiologists Dr. Shanna H. Swan is joined by Dr. Hagai Levine, an Israeli, and Niels Jørgensen, a Danish doctor, and five others. Their goal will be to perform a systematic review and meta-regression analysis, a kind of statistical synthesis of the data—a study on men and their declining production abilities.

Most men can still conceive a child naturally with a depressed sperm count, and those who can't have a booming fertility-treatment industry ready to help them. And though lower sperm counts probably have led to a small decrease in the number of children being conceived, that decline has been masked by sociological changes driving birth rates down even faster: People in the developed world are choosing to have fewer children, and they are having them later.

The problem has been debated among fertility scientists for decades now—studies suggesting that sperm counts are declining have been appearing since the ‘70s.

“We should hope for the best and prepare for the worst and that is the possibility that we will become extinct.” --- Dr.Hagai Levine

Not only were sperm counts per milliliter of semen down by more than 50 percent since 1973, but total sperm counts were down by almost 60 percent: We are producing less semen, and that semen has fewer sperm cells in it. This time around, even scientists who had been skeptical of past analyses had to admit that the study was all but unassailable.

Studies suggest testosterone levels have also dropped precipitously, with effects beginning in utero and extending into adulthood. One of the most significant markers of an organism's sex is something called anogenital distance (AGD)—the measurement between the anus and the genitals. Male AGD is typically twice the length of female, a much more dramatic difference than height or weight or musculature. Lower testosterone leads to a shorter AGD, and a measurement lower than the median correlates to a man being seven times as likely to be subfertile and gives him a greater likelihood of having undescended testicles, testicular tumors, and a smaller penis. “What you are seeing in a number of systems, other developmental systems, is that the sex differences are shrinking,” Swan told me. Men are producing less sperm. They're also becoming less male.

What if it is beyond one’s control happening before birth?

Rare symptoms for a condition referenced to as testicular dysgenesis syndrome (TDS), a collection of male reproductive problems that include hypospadias (an abnormal location for the end of the urethra), cryptorchidism (an undescended testicle), poor semen quality, and testicular cancer. It is proposed by one of the doctors with TDS is that these disorders can have a common fetal origin, a disruption in the development of the male fetus in the womb.

In ever changing DNA makeups the trick will be to stop it at just the very last second. Like you see a countdown timer illustrate on a television show when the hero is disconnecting an explosive device, and at the very last tick, it stops!

So perhaps that's the solution: As long as we hover somewhere above Sperm Count Zero, and with an assist from modern medicine, we have a shot. Men will continue to be essential to the survival of the species. The problem with innovation, though, is that it never stops.

There will be a day when women will no longer require a man. Man will only need a man. The only purpose for man will be not to be — if you believe what is forecast for the future, — next.

A new technology known as IVG—in vitro gametogenesis—is showing early promise at turning embryonic stem cells into sperm. In 2016, Japanese scientists created baby mice by fertilizing normal mouse eggs with sperm created via IVG. The stem cells in question were taken from female mice. There was no need for any males.

Male fertility after 35 can still support conception, but sperm health, hormone balance, and reproductive function may begin to change gradually. At best fertility hospital in chennai, Dr.Aravind's IVF Fertility & Pregnancy Centre helps couples understand these changes early so they can plan pregnancy with more clarity.

Why Age Matters

Many people think only female age affects fertility, but male age can also matter. After 35, sperm count, sperm motility, and sperm quality may slowly decline in some men. This does not mean pregnancy is impossible, but it can make conception take longer.

Common Changes After 35

Some men may notice lower testosterone, slower sperm movement, or more variation in semen analysis results. Lifestyle habits, stress, and health conditions can also affect reproductive health more strongly with age. These factors may not cause symptoms, but they can influence fertility.

Why Testing Helps

A semen analysis is often the first step if conception is delayed. It gives a clear look at sperm health and helps doctors decide whether more fertility evaluation is needed. In some cases, hormone testing or further assessment may be recommended.

What Couples Should Know

If the female partner is also older, timing becomes even more important. Couples should not wait too long before seeking advice if pregnancy has not happened after regular attempts. Early fertility support can help reduce delay and improve planning.
