A 41-year-old man generally produces a healthy amount of sperm, though counts and quality (motility, morphology) may see a gradual decline compared to younger years, with studies suggesting average counts in the 40-60+ million/mL range, but production continues throughout life, even if less efficiently. While sperm production doesn't stop, age after 40 brings slight decreases in sperm concentration, motility, and DNA integrity, though some men remain highly fertile.
A 2020 study found that conception is 30% less likely for men older than 40 than it is for men younger than 30. There are several reasons for this, including that semen volume, total sperm count, and sperm motility (how well the sperm can move toward the egg) all decrease as men age.
It takes about 56–72 days to build up a full load of sperm. Sperm are produced continuously and develop in the testes. They then mature in the epididymis, which may take up to 10 to 14 days. Factors like age, hormones, and ejaculation frequency can affect recovery time.
Male Fertility Facts
Peak male fertility is around 25-29 years old. Sperm quality begins to decline at 30. At 45, men begin to experience a significant decrease in semen volume. Older men can also take longer to conceive a child.
Though women's natural fertility ends with menopause, giving us a defined period of time to study, men continue to produce sperm until the very end of their lives, making pregnancy possible from the sperm of 50-year-olds (and 80-year-olds). There are several issues that affect men as they age related to fertility.
It can be a common misconception that all men remain fertile forever, capable of fathering children at any age. Although men can technically continue producing sperm throughout their entire life, the quality of sperm declines gradually, typically beginning around the mid-to-late 40s.

10 tips for improving fertility in your 40s
After 7 days of not ejaculating, unreleased sperm are reabsorbed by the body, and it's generally considered harmless, though some studies suggest longer abstinence might slightly decrease sperm quality for fertility, while temporary testosterone levels might rise; it's fine unless it's due to a medical issue or causes distress, in which case seeing a doctor is recommended.
No, ejaculating 3 times a day isn't inherently too much; there's no "normal" frequency, and it's generally safe and can offer benefits like stress relief, but it's only "too much" if it causes physical pain, interferes with your life, or feels compulsive. Frequent ejaculation is linked to potential benefits, including reduced prostate cancer risk, though individual experiences vary. Listen to your body for signs like soreness, and remember sperm regenerates quickly, debunking "running out" myths.
The present study showed that antioxidant supplements, especially a combination of antioxidants such as vitamin C, vitamin E, and CoQ10 intake can effectively improve semen parameters in infertile men.
More women and birthing people than ever are getting pregnant in their 40s. Most people over 40 who get pregnant have healthy pregnancies and babies. However, it can take longer to get pregnant and some people have complications. If you're older than 35, you're more likely to conceive more than 1 baby.
According to the World Health Organization (WHO), a regular semen analysis shows a sperm concentration of at least 15 million sperm per millimeter of semen, with at least 30% motility and 4% normal morphology.
The overall picture is that the older the parents (both the mother and the father), the more likely they are to have a daughter.
Human semen is composed of fluids from the seminal vesicles, prostate, and bulbourethral glands which mix during ejaculation. The seminal vesicles contribute 70% of semen volume, which contains fructose as the main energy source for sperm.
The taste of semen varies from person to person, but it will generally be warm, salty, and have a slightly chlorine-like smell. While there are no research-backed guidelines, practicing proper hygiene, as well as a healthy diet and lifestyle, can make your semen taste and smell a little different.
A comprehensive analysis involving over 5.7 million children revealed that children of fathers in their 40s and 50s show a significantly higher prevalence of autism. Specifically, offspring of fathers over 50 are approximately 66% more likely to develop autism than those with fathers under 30.
Older dads and fertility
Just as a woman's chance of conceiving declines after a specific number of birthdays, men's fertility also declines. If you're still in your 20s or 30s, you have a better chance of fathering a child than if you're 40 or older because, before age 40, men have higher-quality sperm.
As women “use up” the eggs they were born with, by age 40, many women deplete their ovarian reserve and have difficulty producing enough good-quality eggs to make it to implantation, even with stimulation.
After adjusting for female age, conception during a 12-month period was 30% less likely for men over age 40 years as compared with men younger than age 30 years. In addition to female age, coital frequency and sexual functioning are variables that affect time to conception and pregnancy rates.
The 7-7-7 rule of parenting generally refers to dedicating three daily 7-minute periods of focused, undistracted connection with your child (morning, after school, bedtime) to build strong bonds and make them feel seen and valued. A less common interpretation involves three developmental stages (0-7 years of play, 7-14 years of teaching, 14-21 years of advising), while another offers a stress-relief breathing technique (7-second inhale, hold, exhale).
A 35-year-old woman has about a one in 350 chance of conceiving a child with Down syndrome, and this chance increases gradually to 1 in 100 by age 40. At age 45 the incidence becomes approximately 1 in 30.
