WHAT IF? If each vas deferens in a male was surgicallysealed off, what changes would you expect in sexualresponse and ejaculate composition?
Which of the following statements about the Female Reproductive System is TRUE?
Select one:
A) Follicles are located in the ovarian cortex, which has a rich supply of blood vessels and nerve fibres.
B) The female gonads secrete progesterone, estrogen, and oxytocin.
C) Connective tissue makes up the walls of the ovaries, uterus, and vagi na – whereas epithelial tissue lines the inner sides of the uterus, Fallopian tubes, and vagina.
D) Microbial growth is deterred by the non-acidic environment of the vagi na.
E) Each ovary is held in place within the abdominopelvic cavity by three ligaments – the broad, suspensory, and uterine ligaments.

- Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.arrow_forwardWith all the sex that occurs in the media, why doesn’t anybody on the soaps or in movies get an STI? (Similarly, hardly anyone gets pregnant unless it’s a made-for-TV movie on the subject.) What messages do they convey about STIs and risk taking? Feel free to reference specific shows/movies. Who should be responsible for safe sex? Should women take a more active role given that most contraceptive methods are made for women? What can men do to encourage safe sex? Discuss the difference between HIV and AIDS.arrow_forwardAfter learning about the reproductive systems, how would advise a couple with following concern: "If we do not want a baby for next two years, how can we calculate the safe sex period?" She shares that her cycle is regular but not standard 28 days long cycle (so the standard explanation form different sources won't work unless you think critically)! At what time of the female cycle is she most likely to prevent fertilization of her ovulated egg? Consider the fact that her cycle is not 28 days but longer or shorter (you pick). Do males have any time (in their cycle- if any) when their gametes would not be able to fertilize the egg? In other words when can intercourse lead to least chance of pregnancy? Feel free to check with your older friends, doctors, nurses, or anyone who you feel comfortable talking about this.arrow_forward
- Gross Anatomy of the Human Male and Female Reproductive System a) Assume that a couple has just consummated the sex act and that the sperm have been deposited in the vagina. Trace the pathway of the sperm through the female reproductive tract. b) Define ovulation. c)The testis is divided into a number of lobes by connective tissue. Each of these lobes contains one to four_______ which converge to empty sperm into another set of tubules called the_______arrow_forwardCompared to the “large number” strategy of the male reproductive system, describe the overall strategy of the female reproductive system. What is the ovarian cycle? What is the menstrual cycle?arrow_forwardms Male Reproductive System Carefully read the following statements and select the correct option. Statement I: Testosterone not only helps during puberty but also promotes good bone density, sperm production, libido, muscle mass and strength. Statement II: Apart from Leydig cells, B-lymphocytes, dendritic cells, macrophages, leukocytes and mast cells are located in the interstitial region of the testes. Statement III: The urethra arises from the urinary bladder and spreads through the vasa efferentia. Statement IV: The supply of blood to the testes is facilitated through tunica vaginalis which is enveloped by the tunica albuginea layer. (a) Statements II and IV are correct, while others are incorrect. (b) Statements I and III are correct, while others are incorrect. (c) Statements I and II are correct, while others are incorrect. (d) Statements II and III are correct, while others are incorrect.arrow_forward
- Understanding the causes of infertility can be valuablein developing new birth control methods. Cite a type ofcontraceptive based on each of the following causes of infertility:(a) failure to ovulate due to a hormonal imbalance;(b) a large fibroid tumor that disturbs the uterine lining;(c) endometrial tissue blocking uterine tubes;(d) low sperm count (too few sperm per ejaculate).arrow_forwardWhat is the relative size of the sperm as compared to the egg?
