- Sperm facts
- A normal sperm count is around forty million sperm per milliliter of ejaculate.7
- Sperm can only survive about six hours in the vagina due to the acidic vaginal secretions.
- The cervical mucus present when ovulation is near, is more alkaline and more hospitable to sperm. This helps them swim more easily through the vagina to the cervix.
- Research has shown that some sperm may survive in the fallopian tubes up to 7 days, with the average amount of time being 3 to 4 days.
- Fertility myths
- Sexual positions don't affect conception
No study has confirmed that one position is more effective than any other in achieving pregnancy. Sperm can be found in the cervical canal mere seconds after ejaculation, regardless of position.
- Standing on your head won't help
Since sperm start swimming immediately after ejaculation, it isn't necessary for a woman to do gymnastics to make a baby.29
- Infertility facts
- Infertility affects both men and women. Research shows that of couples experiencing difficulty getting pregnant, male factors:
- contribute in over half of cases,
- are the only problem for about one-third.30
- About 10% of infertility problems remain unexplained even after complete medical examinations and tests.
- Although many women become pregnant when they are in their 30s or older, women are most fertile in their mid-20s. Fertility declines as a woman ages and then drops rapidly as she enters her mid to late 30s. The most common cause of infertility in the female is an ovulation disorder.31
For men, fertility decreases slowly from around 25 until around 40 years of age and then begins to decrease more rapidly. The most common reasons for male infertility include abnormalities in sperm count, swimming and development.31
