FAQs on Reproduction in Human Beings (Male & Female) Video Lecture - Crash Course: Class 10

1. What is the process of fertilization in human beings?
Ans. Fertilization in human beings is the process of fusion of a sperm cell with an ovum or an egg cell. It occurs in the fallopian tube. The sperm cell travels towards the egg cell and penetrates the outer layer of the egg cell. Once the sperm cell enters the egg cell, the outer layer of the egg cell hardens, and no other sperm can enter. The sperm and egg nuclei fuse, forming a zygote, which then undergoes cell division to form an embryo.
2. What are the primary reproductive organs in males and females?
Ans. The primary reproductive organs in males are the testes, which produce sperm and the hormone testosterone. In females, the primary reproductive organs are the ovaries, which produce eggs and the hormones estrogen and progesterone.
3. What is the menstrual cycle?
Ans. The menstrual cycle is the process in which the female body prepares for pregnancy every month. It is controlled by the hormones estrogen and progesterone. The cycle lasts for about 28 days and involves the growth and shedding of the endometrial lining of the uterus. If the egg is not fertilized, the endometrial lining is shed during menstruation.
4. How does the male reproductive system contribute to fertilization?
Ans. The male reproductive system contributes to fertilization by producing and delivering sperm cells to the female reproductive system. The testes produce sperm cells, which are then stored in the epididymis. During ejaculation, the sperm cells are carried through the vas deferens and mixed with seminal fluid produced by the seminal vesicles, prostate gland and bulbourethral gland. This mixture, called semen, is then ejaculated from the penis into the female reproductive system during sexual intercourse.
5. What are the common problems that can affect human reproduction?
Ans. There are several common problems that can affect human reproduction, including infertility, sexually transmitted infections (STIs), and reproductive cancers. Infertility can be caused by a variety of factors, including hormonal imbalances, blocked fallopian tubes, and low sperm count. STIs can damage the reproductive organs and lead to infertility. Reproductive cancers, such as ovarian, cervical, and prostate cancer, can also affect human reproduction and require prompt medical attention.
