Are some people super fertile?

It's true that fertility is genetic, and there actually are some people who can be classified as “super” fertile. This is all dependent on sperm and egg health. One study on the topic classified super fertility as having a monthly fecundity rate (the ability to get pregnant) of 60% or greater.

What age are females the most fertile?

A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline becomes more rapid once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely for most women.

Is being very fertile genetic?

The short answer is probably not. Your family history is not the biggest factor—or even one of the biggest factors—that affects your fertility. A number of factors can and do contribute to infertility. In women, a common cause is an ovulation (release of the egg) disorder.

Who is more likely to have fertility issues?

Women's fertility gradually declines with age, especially in the mid-30s, and it drops rapidly after age 37.

What age are males most fertile?

What season are men most fertile?

Men with normal sperm production had the healthiest sperm in winter and early spring. They produced 70 million sperm per millileter of semen, compared to 68 million at the end of spring. Further, 5% of winter-produced sperm had fast motility (or speed), which makes conception easier, compared to 3% in spring.

Is white sperm more fertile?

Semen Quality and Male Infertility

The sperm count in white and cloudy semen is better than watery and clear semen. Watery semen may sometimes be considered as an indicator of fertility issues in males. In most cases, clear semen is indicative of a transient problem that may resolve spontaneously.

Does race play a role in fertility?

Race is a determinant of infertility diagnoses, and racial disparities account for a significant proportion of poor health outcomes overall (1). Studies have demonstrated racial disparities in access to infertility care and live birth rates after assisted reproductive technologies (2, 3).
