- Should fertility clinics be required to disclose all the risks of ART to couples seeking fertility treatments? Are state and/or federal laws the best way to achieve this?arrow_forwardJan is concerned about using ART. She wants to be the genetic mother and have Darryl be the genetic father of any children they have. What methods of ART would you recommend to this couple? Jan, a 32-year-old woman, and her husband, Darryl, have been married for 7 years. They have attempted to have a baby on several occasions. Five years ago, they had a first-trimester miscarriage, followed by an ectopic pregnancy later the same year. Jan continued to see her OB/GYN physician for infertility problems but was very dissatisfied with the response. After four miscarriages, she went to see a fertility specialist, who diagnosed her with severe endometriosis and polycystic ovarian disease (detected by hormone studies). The infertility physician explained that these two conditions were hampering her ability to become pregnant and thus making her infertile. She referred Jan to a genetic counselor. At the appointment, the counselor explained to Jan that one form of endometriosis (MIM 131200) can be a genetic disorder, and that polycystic ovarian disease can also be a genetic disorder (MIM 184700) and is one of the most common reproductive disorders among women. The counselor recommended that a detailed family history of both Jan and Darryl would help establish whether Jans problems have a genetic component and whether any of her potential daughters would be at risk for one or both of these disorders. In the meantime, Jan is taking hormones, and she and Darryl are considering alternative modes of reproduction. Using the information in Figure 16.4, explain the reproductive options that are open to Jan and Darryl.arrow_forwardA couple contemplating a pregnancy are in today for an appointment at a genetic counselling clinic to identify and interpret their risk of an inherited disorder.

Intellectual disability d. Characteristic facial features e. Hyperextensible finger jointsarrow_forward

I Think your mother should make an appointment to meet with your obstetrician. I'm sure she knows a lot more about your brother's illness than she is telling you." b. There are a number of tests that can be performed during your pregnancy tO Screen the baby for genetic diseases." c. lt is almost impossible to figure out what happened way back then, but l'm sure everything will be fine with your baby." d.

The egg only survives in the fallopian tube from 24 hours after ovulation, so conception can only happen during a 24-hour period each month. However, this form of contraceptive is very unreliable and is not recommended for couples who are actively trying to avoid pregnancy. Which of the following is NOT a reason why this form of birth control is unreliable? A. Sperm can survive in the fallopian tubes for 3 to 5 days. B. Ovulation can be affected by stress or illness. C. Women always ovulate on the same day of their menstrual cycle every month. D. It is difficult to predict exactly when in her cycle a woman ovulates.arrow_forward

Which of the following possibilities can be eliminated as inheritance pattern for this condition? a) The condition is autosomal dominant O O c) The condition is sex linked recessive b) The condition is sex linked dominant d) All of the above can be eliminatedarrow_forwardA devout Catholic couple is in a dilemma whether to opt for homologous IVF or not after being married for 12 years and still no child of their own. They subjected themselves to infertility work up but to no avail. They tried many sexual activity techniques hoping for a baby but to their dismay none was given to them. They sometimes argue and blame one another because of this problem. The wife is so eager to have a child. The husband is okay with or without a child. They visited the wife’s obstetrician who was responsible also for their infertility work up and suggested if they really want to have a child, they would go for IVF. They have options: they can have their own egg and sperm or they could find a third party for surrogate. They really wanted to have a child of their own and so they come to you for advice since they were thinking to undergo homologous IVF. What is your advice to this Catholic couple?arrow_forward(1) What is the karyotype for men who have an extra Y chromosome? Discuss all the ways you can test for this abnormality.

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) mammalsarrow_forwardIn 2008, two women in New South Wales complained to police that they had suffered considerable distress and concern when they were having lower back x-rays because they had been required to completely undress and to lie in a position that meant their genitals were exposed to the radiographer. Although there was absolutely no clinical justification for this, the women, who were fully competent, had followed the instructions without protest. Does this mean that there was implied consent? Was it therefore acceptable?arrow_forward
