- All of the following are true of spermatogenesis EXCEPT: Question 21 options: The products are spermatozoa that each have a head, midpiece and tail. One spermatogonium produces 4 spermatids DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced. Genetically diverse spermatids are created.TRUE OF FALSE Primary spermatocytes are diploid in number like spermatogonia while spermatocytes are haploid in number. Spermatogenesis is the final stage of reproductive cell division by which there is the development of haploid spermatids into sperm. Spermiation is the event by which sperm are released from their connections to Sertoli cells. Digestive secretions from the small intestine complete the digestion of carbohydrates, proteins, and lipids. Bacteria in the large intestines produce minerals and nucleic acids.Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement). Research treatment options for reduced sperm movement. Describe one option that can be used to aid successful fertilization and explain why it helps.
- In sexual differentiation, parts of the male reproductive system develop from the:A healthy human sperm can range from 30 to 50 micrometers long and contains two distinct structures: the head and neck. Group of answer choices -True -Falsewhich of the following enables males to produce sperm throughout adulthood? type a daughter cells, spermatozoa, type B daughter cells, or primary spermatocytes.
- The increased membrane fluidity has been attributed to the efflux (removal) of a single membrane lipid component. Removal of which component from the sperm’s membrane could increase fluidity without significantly altering the size and/or shape of the sperm cell?The head of a sperm contains a haploid nucleus with 23 chromosomes. True FalseTRUE OR FALSE: Primary spermatocytes are diploid in number like spermatogonia. Secondary spermatocytes are haploid in number.
- Endometriosis is a disorder in which endometrial cells implant and proliferate outside of the uterus—in the uterine tubes, on the ovaries, or even in the pelvic cavity. Offer a theory as to why endometriosis increases a woman’s risk of infertility. Your answer:Infertility strikes both men and women. Describe in a summary the biological causes that impair the process of conception in both males and females. Besides mentioning specific reasons of infertility in males and females, you need to include in your answer other cause(s) that might be the result of a combination of factors originating from both men and women.Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement). Describe how intrauterine insemination can be used to aid successful fertilization and explain why it helps. Make sure that the treatment process AND how the process helps to improve fertility are clearly explained.
