Prostate-specific antigen e. hypospadias. d. Vas deferens The acrosome contains proteins that help the sperm penetrate the outer shell of an egg. The midsection of the sperm contains energy producing mitochondria. These specialized structures provide the energy necessary for the sperm cell to move. The purpose of the sperm tail, or flagellum, is to allow movement. Our results are congruent with previous reports, that exposure to temperatures above preferred temperatures, results in a dramatic decrease in sperm concentration and damages the cells responsible for sperm production. The second function of the testes is to produce sperm. Congenital conditions are those that occur during fetal development. b. Prostate A fundamental change that occurs during capacitation is alkalinization of sperm cytoplasm, in which the intracellular pH levels increase, particularly in the flagellum. Once out of the epididymis, the sperm move to the vas deferens. PCl3(g)+Cl2(g)PCl5(g).

Unless the flow of blood is restored within six hours, the risk of testicular damage and infertility is high. During puberty, testosterone and other In EBT, the radiation source is "radioactive seeds" placed within the tissues. They are where sperm cells are produced and are also responsible for the production of the sex hormone testosterone. c. prior to entering grammar school. b. Tomography The germination phase represents the second phase of growth in the male gametophyte, consisting of three cells. Female gametophyte is the female gamete-producing structure, which comes from the megaspore. Megasporangium produces the megaspores inside the ovary in angiosperms.
