MALE AND female reproductive systems
Most species have male and female sexes both sexes have different and unique reproductive systems. They are different in shape and structure but both shares the same purpose to reproduce (carry the sperm or egg). With human reproductive systems both reproductive systems are located in the lower abdomen.
FEMALE ORGANS:
The major organ of the female reproductive system consists of vagina, cervix, ovaries, fallopian tubes, and vulva.
FEMALE ORGANS:
The major organ of the female reproductive system consists of vagina, cervix, ovaries, fallopian tubes, and vulva.
- Vagina - The vagina is a muscular canal about 7.5 cm long that connects external genitals to uterus. This is where the semen starts its journey to fertilize the egg. . In the process of reproduction, the vagina has two functions, accepting both the penis and the sperm during intercourse. And 9 months later giving birth.
- Cervix - The cervix’s opening is between the uterus and the vagina
- Ovaries - The ovaries are the main reproductive organs of a female. There are two Ovaries that are about the size and shape of an almond, they produce female hormones (oestrogen and progesterone) and eggs. All the other female reproductive organs transport the egg around the body to the uterus where the fertilised egg develops. The ovary contains ovarian follicles, in which the eggs develop. Once a follicle is mature, it ruptures and releases the egg.
- Fallopian Tube - The Fallopian tube is linked to the ovaries and the uterus, fertilisation of the egg occurs here.
- Vulva - The vulva is an organ that is outside of the lower abdomen and between the legs. Their function is to help protect the inner organs.
- Uterus - The uterus is a cavity about size of an apple (before a woman has had a baby) that exists to house a fertilised egg. The main part of the uterus (which sits in the pelvic area) is called body of the uterus; the thick wall of uterus is composed of three layers. The inner layer is known as the endometrial. If an egg has been inseminated it will burrow into the endometrial layer, where it will stay until it’s fully-grown.
MALE REPRODUCTIVE SYSTEM:
The main reproductive organs of the male body are the testes, which produce the sperm and also hormones such as testosterone. The male reproductive system also includes the external genitals — the penis and the scrotum (balls) — and the internal organs, including the prostate gland, the vas deferens the, urethra, and the seminal vesicles.

- Testes -The paired oval testes, also known as the male gonads (balls), hang in the scrotal sac. Usually the right testis hangs higher than the left. The testes are outside the body because the temperature inside the body is too warm to produce sperm, so they are produced outside the body because its 3 °C lower than body temperature.
- Epididymis- The epididymis is a collection of many coils of 20-foot long tubes. The function of the epididymis is to collect the immature sperm from the testis. As the sperm make their journey through the epididymis they become mature. This journey takes about 20 days on the way the sperm become fertile and they also become able to move in a swimming motion.
- Vas deferens Joined to the epididymis is the vas deferens — a thick layered tube which transports sperm from the epididymis up to the prostate. The section of the vas deferens that is above the testis can be felt through the loose part of the scrotum. When a vasectomy is performed, it is this part of the vas deferens is cut. The vas deferens empties into the ejaculatory duct.
- urethra The urethra serves as the tube down which urine passes from the bladder through the penis to the outside and also the tube down which semen is ejaculated.
- prostate The prostate is shaped like a walnut. It is the gland that surrounding the urethra. Along with the seminal vesicles it produces the fluid secretions that nourish and help grow the sperm. Without this fluid to dilute them the sperm cannot move easily. After the age of 40 the prostate enlarges and can press on the urethra. An enlarged prostate is often the cause of urinary problems in older men.
