Although advanced age plays a much more important role in predicting female infertility, couples in which the male partner is 40 years old or older are more likely to report difficulty conceiving. Being overweight or obese. Smoking. Excessive alcohol and drug use (opioids, marijuana).
The most common overall cause of female infertility is the failure to ovulate, which occurs in 40% of women with infertility issues. Not ovulating can result from several causes, such as: Ovarian or gynecological conditions, such as primary ovarian insufficiency (POI) or polycystic ovary syndrome (PCOS)
Infertility is more common than many may think. It affects one in eight heterosexual couples who are trying to get pregnant. Overall, 12 to 15% of people are infertile. As a reproductive endocrinologist, my colleagues and I witness firsthand the impact that infertility has on people who desire to have a baby.
Some have found that married Black and Latina women are more likely to be infertile than White women 4,5. Black and Latina women are less likely to seek fertility treatment than their White counterparts 6. Also, Black women take more years to seek fertility treatment than White women 6.
Retrieved June 14, 2023, from www.marchofdimes.org/peristats. In the United States, the highest fertility rates (per 1,000 women ages 15-44) during 2018-2020 (average) were to Hispanic women (64.8), followed by blacks (62.6), American Indian/Alaska Natives (60.8), Asian/Pacific Islanders (55.6) and Whites (55.3).
Asians had the highest mean semen concentrations (69.2 × 106/mL), whereas blacks had the lowest (51.3 × 106/mL).
What Causes Infertility? Problems with ovulation are the most common reasons for infertility in women. A woman's age, hormonal imbalances, weight, exposure to chemicals or radiation and cigarette smoking all have an impact on fertility.
If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.
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 happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
The main symptom of infertility is the inability to get pregnant. A menstrual cycle that's too long (35 days or more), too short (less than 21 days), irregular or absent can mean that you're not ovulating. There might be no other signs or symptoms.
A trained expert checks your sperm count, their shape, movement, and other characteristics. In general, if you have a higher number of normal-shaped sperm, it means you have higher fertility. But there are plenty of exceptions to this. A lot of guys with low sperm counts or abnormal semen are still fertile.
Is infertility a common problem? Yes. About 10 percent of women (6.1 million) in the United States ages 15-44 have difficulty getting pregnant or staying pregnant, according to the Centers for Disease Control and Prevention (CDC).
A number of lifestyle factors affect fertility in women, in men, or in both. These include but are not limited to nutrition, weight, and exercise; physical and psychological stress; environmental and occupational exposures; substance and drug use and abuse; and medications.
You could be worrying that you never will. However, there are many possible reasons why you aren't conceiving, including ovulation irregularities, structural problems in the reproductive system, low sperm count, underlying medical problems, or simply not trying enough.
Danish men had the lowest sperm concentrations whilst Finnish men had the highest [14]. Such geographical differences in semen characteristics as presented by these studies remain unexplained.
Their results showed that those of East Asian descent had the highest median sperm concentrations (90 million/mL), followed by Whites (88 million/mL), Hispanics (73 million/mL), Native Americans (72 million/mL), South Asians (64 million/mL), and Blacks (59 million/mL).
You're more likely to have a girl if…
The male has a low sperm count. It could occur naturally or due to certain factors such as heat, particular drugs and toxic substances which kill many male sperm cells, according to Shettles.
These studies showed that women of Asian descent had lower average BMI, good embryo quality and number of embryos produced, normal hormone levels, and healthier diets which usually contribute to higher fertility.
Angola, Benin, DR Congo, Mali, and Niger have the highest TFR. The most populous country in Africa, Nigeria, had an estimated TFR of 4.57 in 2023. The second most populous country, Ethiopia, had an estimated TFR of 3.92 in 2023.
Mariam Nabatanzi Babirye (born December 25, 1980) also known as Maama Uganda or Mother Uganda is the most fertile woman in the world. She has given birth to a total number of 44 children, 38 of whom are alive. As of April 2023, her eldest children are 28 years and the youngest are 6 years old.
