Understand the Role of Sperm and Ovum
Sperm and ovum are the male and female reproductive cells, also known as gametes. The sperm is a tiny, motile cell produced in the testes, while the ovum is a large, non-motile cell produced in the ovary. Sperm carry either X or Y chromosomes, determining the baby’s sex, while the ovum always carries an X chromosome. Both cells play a crucial role in fertilisation, leading to the formation of a new life. However, there are some key differences between sperm and ovum, which we will explore in this article.

Yes, if the egg is not healthy or the sperm is defective, fertilisation may not happen.
7. How long can sperm survive?
Sperm can survive inside a female body for up to 5 days under the right conditions.
