0 views

For a successful pregnancy, a single sperm is theoretically enough to fertilize an egg, but the odds of pregnancy increase with a higher sperm count. Generally, ejaculates contain millions of sperm, but healthy sperm counts range from 15 million to more than 200 million sperm per milliliter of semen. Low sperm counts may decrease the probability of conception, but various fertility treatments and techniques can assist individuals with lower counts in achieving pregnancy.
