Male Reproductive system

The male reproductive system is made up of the penis and two testes. Inside the testes, sperm cells are created in a process called spermatogenesis. The sperm then passes through tubes called the vas deferens, where they mix with seminal fluid to form sem en. The two structures that make up the male reproductive system are collectively known as the genitourinary system.

 

Female Reproductive system

The female reproductive system is made up of the vag ina, uterus, fallopian tubes and ovaries. The uterus is a hollow, pear-shaped organ in which a developing fetus grows. The vag ina connects the uterus to the outside of the body. It also serves as a conduit for menstrual flow from the uterus. The fallopian tubes are two slender tubes that lead from each ovary to one side of the uterus.

 

Stages of reproduction

The process of reproduction starts with a sperm cell from the male and an egg from the female, which then combine to create a zygote. This is the first stage of reproduction. The next stage involves the growth of this zygote into an embryo, during which it will develop into a fetus and fully mature. Finally, birth takes place when the baby emerges from its mother’s body through her vag ina.

 

Organelles in sexual reproduction

In sexual reproduction, the two haploid cells come together to form a new diploid cell. One of these cells is called the female gamete, which is also called an egg cell or oocyte. The other cell is called the male gamete, or sperm. The sperm carries 23 chromosomes while the egg has 22 chromosomes, with one chromosome coming from either parent.

 

Special cells for sexual reproduction

The male gamete, or sperm cell, contains a haploid number of chromosomes (23) and is relatively small. The female gamete, or egg cell, contains a haploid number of chromosomes (23) and is much larger than the sperm cell. This allows for fertilization to occur when the two cells meet inside the woman’s body.

 

Fertilisation and development

Fertilisation is the process in which a sperm cell and an ovum (egg) come together to form a zygote. The zygote then develops into an embryo, which may or may not implant in the uterus. In mammals, implantation usually occurs about 7 days after fertilisation. This is called pregnancy.
