Definition - What does Semen mean?
Semen is a light grey to clear fluid which is released through the penis during an orgasm. It consists of several different substances including sperm, enzymes, fructose, lubricant, vitamins, etc. each of which come from different parts of the male sexual organs.
Each of the components listed above plays an important role in sperm’s ability to travel to and fertilize the egg, which can eventually lead to pregnancy. Male infertility affects approximately 7% of all men, and it is commonly due to deficiencies in semen.
FertilitySmarts explains Semen
Sperm is made in the testicles and it is then transported to the epididymis. When ejaculation occurs, the sperm stored in the vas deferens is sent through the prostate into the urethra, as it moves through the male reproductive tract, various elements are added to the sperm, creating the semen mixture. The rhythmic muscle movements of the penis propels the semen forward. If it survives the environment of the vagina, it can travel up to the uterus or fallopian tubes where it is able to fertilize the egg.
A semen analysis may be performed in order to determine both the quantity and quality of a man’s semen. It can help to determine if a man’s sperm is the cause of infertility, either due to a low sperm count, poor movement, abnormal sperm morphology, or infection, among other things.
