Most contraceptive pills are designed for the female reproductive system. In a scientific innovation challenge, you are to present an idea for the development of a contraceptive pill for males. From your knowledge of the reproductive and endocrine systems of the male body, tell us how this pill when taken by a male will work to prevent pregnancy.
Step by step
Solved in 2 steps
- After 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.In vitro fertilization (IVF) is a common assistive reproductive technology for couples who are struggling to conceive naturally; however, the success rate of IVF is, at best, about 55%. Researchers seeking to improve the success of IVF need to observe the interaction between sperm and eggs in order to better understand the factors that favour fertilization. Obviously, larger sperm and eggs would be easier to observe, even with the aid of microscopy. On this basis, which of the following vertebrate groups might be a good model for studying IVF because they are likely contain species with large sperm and eggs? Group of answer choices a) fish b) amphibians c) reptiles d) birds e) mammalsHormone replacement therapy was advertised first to women in the 1990s as a way of increasing their youthfulness. Hormone replacement therapy today is usually taking pills to increase someone's estrogen or testosterone supply. Pick either estrogen or testosterone. For either one: 1) How does your chosen sex hormone work at the cellular and at the molecular level? 2) How do these hormones improve the reproductive system as a whole? 3) What are the benefits of doing hormone replacement therapy? 4) What are the harms of doing hormone replacement therapy? 5) Who would be an ideal candidate for hormone replacement therapy?
- Each one of the different contraceptive methods has its pros and cons. Give an example of a method listed below and cite the pros and cons behind its use. Method of Contraception Example Pros Cons Natural Hormonal Barrier Permanent The debate on contraception is based on arguments emerging from the traditional and bioethical positions on contraception. Evaluate whether those positions are philosophically or ethically viable.

- At one time, if a farmer wanted to improve his or her cattle herd, he or she would have to buy an expensive bull from another farmer who had a herd proven to show desirable characteristics. Now, semen from bulls with desirable characteristics can be shipped all over the world to help farmers improve their herds. Use the Internet to learn more about the use of artificial insemination (AI) as a cattle-breeding option. (a) What are the primary advantages and disadvantages of using AI to breed cattle? (b) How popular is AI as a breeding method for the beef and dairy industry?Hi can I get help with this question please? I am stuck!! Topic is sexual reproduction and its physiology. Scenario: Drew T. is a 22-year old man who has trouble producing sperm. The medical doctors identify that the problem is with the Luteinizing Hormone (LH) receptors on his Leydig cells. He comes to you confused because he thought it was the Sertoli cells that produced sperm. You explain to Drew…(see image)In January 2009, Natalie Suleman successfully gave birth to octuplets and became known as Octomom. She already had 6 children, and all 14 of her children were conceived via in vitro fertilization (IVF). IVF involves removing eggs from the ovary, fertilizing them with sperm in a petri dish, and transferring the resulting embryos back into a uterus to develop. It is common for two or three embryos to be transferred into the uterus of a woman undergoing IVF to increase the chances of at least one of them surviving. When Ms. Suleman became pregnant with her octuplets, Dr. Kamrava had transferred 12 embryos. His license was revoked in 2011.Multiple eggs are required for IVF to produce functional embryos because some eggs are not fertilized or do not develop normally after fertilization. Which of the following hormones would be used to stimulate the ovaries to produce multiple eggs? Select one: a. Testosterone b. FSH c. Progesterone d. Estrogen
- Recall what you learned in class about the experiments that examined the effect of early treatment with hormones on adult reproductive behavior. Match the following behavioral outcomes with each of the manipulations in the questions below. Each answer may be used more than once. An XY animal is castrated (gonadectomized) at birth and treated with testosterone the same day and the next day. What reproductive behavior, if any will this animal show when treated with testosterone as an adult? An XY animal is castrated (gonadectomized) at birth and treated with estradiol the same day and the next day. What reproductive behavior, if any will this animal show when treated with estradiol and progesterone as an adult? An XX animal is not surgically manipulated, but is treated with testosterone on the day of its birth and the day…What defines our biological sex? What is the distinction between genetic and anatomical sexuality? Explain how chromosomes influence the internal and outward development of the sexual anatomy (hormones and structures). Is there always a correlation between genetic and anatomical sex? What is the reason, or why not? Describe a situation or disorder in which the internal and exterior sexual anatomy of a person do not match and explain how this would occur. Describe how a binary (male/female) model of sex does not reflect reality. What would a more accurate model look like?Which of the following is a result of prolactin. milk production, the uterine cycle, for distribution, breast development, or body hair distribution
