2014 University of Phoenix Instructor – Dr. Zaleski In fertilization, the organs that make up the reproductive system in males plays the role of producing and discharging sperm within the female reproductive tract. The penis, scrotum, testes, sperm, epididymis, and accessory organs make up the reproductive organs in a male. In addition to being used for sexual intercourse and the pathway for semen, the penis is also where urine is passed through. The scrotum

by the 1996 article “The Egg and the Sperm” by Emily Martin in An Introduction to Women’s Studies: Gender in a Transnational World (2006). “The Egg and the Sperm” explores how women’s and men’s reproductive systems translate to how the different genders are perceived within society. One main point of the article is that women are wasteful and passive while the male is viewed as strong, powerful, and energetic. This view is based in the reproductive system because “the egg is seen as large and passive

others, so can metaphors and messages that you can convey through your language in reputable publications. A situation that can represent this concept can be clearly discerned in David H. Freedman’s article “New Theory on How The Aggressive Egg Attracts Sperm”. Written in 1992, this article brings to light an unnerving reality about the world of research, that metaphors and preconceptions that many researchers may have can have genuine effects on the types of research being performing or more alarmingly

mammalian sperm. (A) The centriole produces a long flagellum at what will be the posterior end of the sperm, and the golgi apparatus forms the acrosomal vesicle at the future anterior end. The mitochondria collect around the flagellum near the base of the haploid nucleus and become incorporated into the midpiece ("neck") of the sperm. The remaining cytoplasm is jettisoned and the nucleus condenses. The size of the mature sperm has been enlarged relative to the other stages. (B) Mature bull sperm. The

vagina. He releases millions of sperm when ejaculation occurs. And the sperm have been deposited they have a long and arduous journey ahead of them, like salmon entering the mouth of a river to swim upstream to spawn. Some of the sperm swim straight up into the fallopian tubes through the cervix and uterus. - And some of them are so fast, that sperms have been found in the tubes in as little as a few minutes after ejaculation. I’m one of them joining the rides. Some sperms die in the acidic vaginal fluid;

reproductive organs. First the sperm cells are created within a man's testicles and a woman's egg is matured and produced by her ovary. All of our cells have 46 chromosomes, but sperm and egg cells have 23 each. When they meet and fertilize, you will have combined 46 chromosomes. Each sperm and egg cell carries different genetic info, therefore producing different individuals. Each has their own unique DNA, which is why a person looks different from their siblings, etc. When sperm is deposited into the vagina

The penis fits into the vagina allowing to provide its function effectively. The male testicles are also better outside of the body because sperm have to be at a different temperature than the rest of the body. Being on the outside provides the distance from the body to be provided by the outside world and it natural temperature. Tubes on the inside are placed like hoses in a lawn that have

Snap! Sperm cell Sexual reproduction occurs when offspring result from the joining (fusion) of a male reproductive cell and a female reproductive cell. These special reproductive cells are called gametes and are made in the reproductive organs of organisms. In animals, male gametes are called sperm and female gametes are called ova (singular = ovum) or egg cells. Reproductive systems are designed to bring the male and female gametes together. The joining of sperm and egg cells is called fertilisation
