Researchers say it becomes more difficult for men to father children as they age, especially if their female partner is older, too.

For women, menopause is a signal that female fertility doesn’t last forever.

Men, on the other hand, constantly produce new sperm and some men past the age of 80 occasionally father children. That fuels the myth that men remain fertile all of their lives and can parent children as long as they can perform sexually. In reality, men’s fertility also may decline with age and, as a new study on older men taking part in in-vitro fertilization (IVF) shows, sometimes that decline is quite dramatic. Researchers led by Dr. Guy Morris from the Centre for Reproductive and Genetic Health in London have concluded that IVF success rates decline significantly among men over age 51 — coincidentally, the same average age that women enter menopause. The study of nearly 5,000 IVF and intracytoplasmic sperm injection (ICSI, where a single sperm is injected into an egg) attempts determined that 42 percent of men over age 51 met the World Health Organization’s standard for semen quality, compared to 61 percent of men under age 51. In turn, researchers found that IVF/ICSI pregnancy rates declined as women aged. But they found that the same was also true of men. Nearly half of male IVF/ICSI participants under age 35 in the study were able to successfully fertilize an egg. Among those ages 36 to 40, that rate fell to 42 percent and to 35 percent among men ages 41 to 45. By ages 46 to 50, the success rate was down to 32 percent. And men over age 51 were able to facilitate pregnancy just 30 percent of the time. “This drop-off will also be related to the maternal age and this decline in pregnancy rate becomes quite dramatic over 35 years for a woman,” Morris told Healthline. “Coupled with the effect of an older male partner, we were not too surprised by these rates.” Like most couples, IVF/ICSI patients tend to be close in age. Among women, fertility begins to decline at age 32 , studies have shown — well before most women reach menopause. The study authors, who presented the findings at the recent annual meeting of the European Society of Reproduction and Embryology, described the results as “a public health message for men to not delay fatherhood.” “Stories of celebrity men fathering children into their 60s may give a skewed perspective on the potential risks of delaying fatherhood,” said Morris. “Indeed, in natural conception and pregnancy it is only recently that evidence of risks associated with later fatherhood has become available. These more recent studies contrast with decades of evidence of the impact that maternal age has on fertility outcomes.” Morris added, however, that “applying this to men outside of fertility treatment should be done with caution, as we were not studying that cohort.”

Early Signs of Prostate Cancer

There are no warning signs of early prostate cancer. You can’t feel the growing tumor pushing against anything else, so there’s no pain. You can have the disease for years and not know it. That’s why regular prostate cancer screenings are so important. If you’re a Black man, early screening for prostate cancer is particularly important as you’re 2.5 times more likely to die from prostate cancer than your non-Hispanic white peers. In a large study by JAMA Oncology, results pointed to factors such as access to quality health care as to why this may be the case. If you’re nonbinary or gender expansive, you should still be aware of potential risks of prostate cancer, particularly for transgender women. Significant studies are lacking, but it is still possible to be diagnosed with prostate cancer. So screening, especially if you have symptoms or a family history of cancer, could be a helpful decision.
