Male fertility generally starts to reduce around age 40 to 45 years when sperm quality decreases. Increasing male age reduces the overall chances of pregnancy and increases time to pregnancy (the number of menstrual cycles it takes to become pregnant) and the risk of miscarriage and fetal death.
Men over the age of 35–40 typically experience a decrease in sperm health, which affects: Pregnancy rates. Pregnancy rates decrease with paternal age. Men will generally see a 52% decrease in fertility rate between their early 30s and their mid-to-late 30s.
The age where a man is most fertile is between 22 and 25 years. It is suggested to have children before the age of 35. After this age, the male fertility begins to worsen. After 35, the sperm might result in pregnancies where mutations can occur.
Age and sperm
Men younger than 40 have a better chance of fathering a child than those older than 40. The quality of the sperm men produce seems to decline as they get older. Most men make millions of new sperm every day, but men older than 40 have fewer healthy sperm than younger men.
Although men never stop producing sperm throughout their lives, sperm production does begin decreasing after age 35. Motility, volume and genetic quality of sperm of older men are less likely to achieve a successful pregnancy even in younger women.
Fertility is most likely if the semen discharged in a single ejaculation (ejaculate) contains at least 15 million sperm per milliliter. Too little sperm in an ejaculation might make it more difficult to get pregnant because there are fewer candidates available to fertilize the egg.
It is in sub-Saharan Africa that male fertility is highest, notably in the Sahelian countries, with 13.6 children per man on average in Niger, 13.5 in South Sudan and 12.1 in Chad. In only four countries (South Africa, Botswana, Lesotho and Namibia) is male fertility below 6 children per man.
Causes of male infertility
These may include: Abnormal sperm production or function due to undescended testicles, genetic defects, health problems such as diabetes, or infections such as chlamydia, gonorrhea, mumps or HIV. Enlarged veins in the testes (varicocele) also can affect the quality of sperm.
First, doctors will request a semen analysis – a test to look at your sperm. You ejaculate into a cup, and your sperm will be analyzed under a microscope. To get the best results, do not ejaculate for two to five days before your visit.
When am I most fertile? The most fertile time in your cycle are the days leading up to ovulation, before the egg is released from the ovary. After ovulation the egg survives for just 24 hours, while sperm retain fertilising capability for two to three days in the fallopian tubes.

The most common issues that lead to infertility in men are problems that affect how the testicles work. Other problems are hormone imbalances or blockages or absence of some of the ducts in the male reproductive organs. Lifestyle factors and age-related factors also play a role in male infertility.
Frequent male masturbation isn't likely to have much effect on your fertility. Some data shows that optimum semen quality occurs after two to three days of no ejaculation. But other research suggests that men who have normal sperm quality maintain normal sperm motility and concentrations even with daily ejaculation.

Medication can treat some issues that affect male fertility, including hormone imbalances and erectile dysfunction. Surgery can be effective for repairing blockages in the tubes that transport sperm. Surgery can also be used for repair of varicocele.
Even men who have low sperm production as a cause of no sperm in the ejaculate can be treated with surgery to find sperm, together with assisted reproduction, since several million sperm have to be made in the testicles before sperm survive to make it into the semen.
Seeing a male infertility specialist
We start with a good conversation, a comprehensive physical exam, a semen analysis and blood tests. This often points the doctor in the right direction, allowing a specialized treatment plan to be made. Many times, the problem is correctable.
Low sperm count symptoms might include: Problems with sexual function — for example, low sex drive or difficulty maintaining an erection (erectile dysfunction) Pain, swelling or a lump in the testicle area. Decreased facial or body hair or other signs of a chromosome or hormone abnormality.
excessive alcohol consumption, smoking and using drugs such as marijuana or cocaine. certain medications, including testosterone replacement therapy, long-term anabolic steroid use, cancer medications (chemotherapy), some antibiotics and some antidepressants. being overweight or obese.
About 9% of men and about 11% of women of reproductive age in the United States have experienced fertility problems. In one-third of infertile couples, the problem is with the man.
For a home sperm test, you collect a semen sample by ejaculating into a small cup. A home sperm test may be appealing because you can do it in the privacy of your own home. Results are often ready within a few minutes.
Not all male infertility is permanent or untreatable; it is not uncommon for men to treat infertility through one or a combination of actions.
