Patient's question:
Hello, I would like to ask how many normal sperm count is for men? Because we have been having intercourse for over a year and still haven't had a child, and the sperm survival rate test showed 42%. Is this normal? Also, how many normal sperm are required for conception? How many normal sperm are needed for conception?Doctor's answer:
The normal volume of semen released by a man in a single ejaculation is approximately 2 to 6 milliliters, and anything less than 1 milliliter is considered oligospermia. Oligospermia can cause sperm to lose vitality and function, leading to infertility. Causes of reduced semen volume include: ① Obstruction of the ejaculatory duct or congenital absence of the seminal vesicles; ② Disorders of the pituitary gland or Leydig cells, resulting in decreased gonadotropin levels or reduced estrogen, leading to decreased semen production; ③ Infectious diseases of the reproductive tract can also cause dysfunction of accessory glands, resulting in reduced semen production. It is recommended that you visit a hospital for relevant examinations to rule out underlying medical causes.
