Covering the head of the sperm is a cap known as the acrosome, which contains enzymes that help sperm to enter an egg. Only one sperm fertilizes each egg, even though 300,000,000 to 400,000,000 sperm are contained in an average ejaculation.   out of the approximately 5,000 sperm that enter the utero-tubal junction, about 1,000 get inside the fallopian tube. Finally, out of the 1,000 that enter the tube, it is estimated that only 200 make it to the egg. More human sperm were found to enter cervical mucus in vitro when an inseminate was diluted 11 with whole seminal plasma than when it was diluted with tyrodes medium, even though the sperm swam faster in the medium (overstreet et al.). Thats because the opening of the cervix, known as the external os, is too narrow for a penis or dildo to enter.   something magical is about to happen! Watch as the ovulation process occurs, and then millions of sperm swim upstream on a quest to fertilize an egg. Also called sperm density, this is the number of sperm in millions per milliliter of semen. Sperm goes thru the females body and travels thru there to the egg and creates a baby.   sperm retrieval and collection are usually performed for a condition called azoospermia where a man has no measureable amounts of sperm in his semen. The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy. Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.
