How often should a man release sperm?

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.


How much sperm is needed to fertilize an egg?

Only one sperm needs to survive in order to fertilize an egg. However, the journey from the man's testicle to the woman's uterus is long and arduous.

After ejaculation, a single sperm cell measuring only 0.5 mm needs to swim over 152 mm from the base of the cervix to the egg for fertilization. Not every sperm is up to the task.

Even though only one sperm is needed for fertilization, most sperm cells will not survive the journey from the testicle to the uterus. Of the 200 million sperm deposited near the cervix in an average ejaculation, only 100,000 make it to the womb.

For this reason, it's important to have a healthy sperm count when TTC. You should at least meet a minimum threshold of sperm per ejaculation for optimal fertility.
