Health Desk: Sperm and semen words are commonly used in terms of reproductive capacity and reproductive health. However, there are some significant differences between these two. According to science, both semen and sperm have their own different functions and importance. Semen supports the reproductive process, while sperm are responsible for conception.

1. Definition:

Semen is a fluid, which is excreted by the reproductive organs of the male. It contains sperm, water, protein, minerals and other chemical substances. It is a major substance helping in childbirth. While sperm is a part of semen. It is the reproductive cells of the male present in the semen, whose main role is to fertilize the egg.

2. Structure:

Semen contains millions of sperm, but in addition, it is also rich in other chemical and nutrients, such as fructose, lipids, proteins and minerals. At the same time, sperm is a single reproductive cell, which consists of three main parts: the head (which contains DNA), midpiece (for energy) and tail (from which it floats).

3. Work:

The main function of semen is to keep sperm safe in the atmosphere and help them reach the egg. It helps to keep sperm alive after exiting the body. Whereas, the main function of sperm is to fertilize the egg, which leads to the process of conception.

4. Number:

A normal semen ejaculates about 2–5 ml semen, which contains about 200–300 million sperm. At the same time, the number of sperm is in large quantities in semen, but only a few sperm are able to reach the eggs and are able to fertilize.

5. Color and Form:

The color of the semen is light white or yellow, which is caused by a mixture of chemical substances other than sperm. While the sperm size is very small, and it is made up of a round head, a long thread -like midpiece and tail, which helps it to swim.

6. The ability to survive:

The atmosphere of semen suits sperm alive and reach the eggs. The pH and chemical composition of semen increases the lifetime of sperm. Whereas, sperm can survive out of the body for a few hours, but if they reach the reproductive tract of women, they can survive for 3-5 days.
