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.
They found that the most significant factor contributing to probability of pregnancy was the age of the male partner. After six cycles, men aged ≥ 35 years had fertility rates of 25% compared with fertility rates of 52% in men aged < 35 years, representing a 52% decrease in fertility rate.
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.
For healthy semen samples collected between 5:00am and 7:30am were found to exhibit a statistically higher sperm concentration, total sperm count and a higher percentage of normally shaped sperm, compared to samples produced later in the day.
Men can produce sperm from puberty to a ripe old age and continue to father children as long as they do so. Women, on the other hand, have a limited fertile window. Past 51 – the average age of menopause – they cease to release any eggs and become infertile. Both men and women are delaying having children.
Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
Healthy sperm have rounded heads and long, strong tails. Shapely sperm are more likely to make it to an egg.
Time of day: Sperm counts are higher in the morning. Excessive ejaculation and prolonged abstinence: Both are known to affect the number and quality of sperm. Intercourse every two to three days helps ensure optimal sperm count and health.
Sperm counts may be higher in the morning for a number of reasons, including but not limited to whether you have sex during the day. It is generally agreed that the time that you have sex during the day doesn't significantly impact on your chances of getting pregnant.
Some research says that yes, sperm may be more potent in the morning. But other studies suggest it's more potent in the afternoon or that it doesn't change at all. Whatever the case, it's highly unlikely that the time of day you have sex will affect your chances of conceiving.
You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant.
