Most people think of the gonads as the male testicles. But both sexes have gonads: In females the gonads are the ovaries, which make female gametes (eggs).
What are the organs which produce gametes?
The primary reproductive organs, or gonads, consist of the ovaries and testes. These organs are responsible for producing the egg and sperm cells gametes), and hormones.
Does the uterus produce female gametes?
At the upper corners of the uterus, the fallopian tubes connect the uterus to the ovaries. The ovaries are two oval-shaped organs that lie to the upper right and left of the uterus. They produce, store, and release eggs into the fallopian tubes in the process called ovulation (av-yoo-LAY-shun).
In which organ male gametes are produced?
The two testicles (or testes) produce sperm and the male sex hormone testosterone.
Which part of the human body passes sperm from a man to a woman?
In this process, the male inserts his penis into the female’s vagina and ejaculates semen, which contains sperm. A small proportion of the sperm pass through the cervix into the uterus, and then into the Fallopian tubes for fertilization of the ovum.
Is a sperm a cell?
In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system.
How do female gametes exit the body?
About once a month, during ovulation, an ovary sends a tiny egg into one of the fallopian tubes. Unless the egg is fertilized by a sperm while in the fallopian tube, the egg leaves the body about 2 weeks later through the uterus — this is menstruation.
Which ovary produces a girl?
In the normal female the ovary of the right side yields ova which on fertilization develop as males, and the ovary of the left side yields ova which are potentially female.
When do females produce their supply of gametes?
The ovaries are filled with follicles. Follicles are fluid-filled structures in which the oocyte (also called egg) grows to maturity. Current knowledge indicates that females are born with their entire lifetime supply of gametes. At birth, the normal female ovary contains about 1-2 million/oocytes (eggs).
Why do men produce more gametes?
The sex that produces small and numerous gametes (that is, the male) will more-often-than-not have higher potential reproductive rates. The primary consequence of anisogamy is therefore that reproductive competition (for mates – i.e. sexual selection) will generally be greater in males.
What is the release of male gametes called?
Spermatogenesis is the process of male gamete formation in animals. This process also involves meiosis occurring in the diploid primary spermatocyte to produce the haploid spermatozoon.
