Sperm, also known as sperm cells, are composed of a cell membrane, cytoplasm, and nucleus and have a reproductive function.
Sperm is a cell, like a normal animal cell, composed of cell membrane, cytoplasm and nucleus.
Normal spermatozoa are in the shape of a tadpole, with a total length of about 60 μm, and can be roughly divided into two parts: the head and the tail. The head is oval in shape, about 4-5 μm in length and 2.5-3.5 μm in width.Sperm is produced by the testes, usually developed and stored in the epididymis, and expelled from the body during sexual intercourse or masturbation.
Sperm plays an important role in the reproduction of our offspring. Sperm contains the male genetic material, known as DNA, which when combined with the DNA in the female’s egg forms a fertilized egg, which in turn develops into an embryo.
It is recommended to have a moderate and regular sex life, quit smoking and drinking, and exercise properly to enhance physical fitness, which will help to improve the quality of sperm. If you have not yet conceived after 1 year or more after marriage, it is recommended that both husband and wife go to a regular hospital at the same time to actively improve the relevant examinations and receive treatment as soon as possible.
