Watch this video (http://openstaxcollege.org/l/vasectomy) to learn about vasectomy. As described in thisvideo, a vasectomy is a procedure in which a small sectionof the ductus (vas) deferens is removed from the scrotum.This interrupts the path taken by sperm through the ductusdeferens. If sperm do not exit through the vas, eitherbecause the man has had a vasectomy or has not ejaculated,in what region of the testis do they remain?

Please Explain! A repeat semen analysis for fertility testing is reported as follows: VOLUME: 3.5 mL SPERM CONCENTRATION: 6 million/mL VISCOSITY: Normal SPERM MOTILITY: 30%—grade 1.0 PH: 7.5 MORPHOLOGY: <30% normal-forms—30 spermatids/100 sperm The results correspond with the first analysis. Which of the test results are abnormal? What is the sperm count on this specimen? What is the spermatid count? Based on the spermatid count, what additional test can be performed?

Which of the following lists the female reproductive structures that sperm will pass through on their way to fertilize an oocyte, in the correct order? a. cervix . . . vagina . . . oviduct . . . ovary b. cervix . . . oviduct . . . vagina . . . uterus c. uterus . . . cervix . . . vagina . . . ovary d. vagina . . . cervix . . . uterus . . . oviduct
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.
