In the “fertility awareness” method of birth control, a woman gauges her monthly fertile period by monitoring changes in the consistency of her vaginal mucus. What kind of information does such a method provide about the likelihood of getting pregnant?

Envision yourself as a physician whose patients sometimes ask about birth control. Provide a contraceptive method for each of the following patients, and explain why it would be appropriate: couple A, a man and woman who have intercourse regularly but never want to have children; couple B, a man and woman who have intercourse regularly and want to have children someday; and person C, a single woman who occasionally has intercourse with single men and does not wish to become pregnant. Be sure to include the level of protection against STDs that each person is likely to need.
Conditions that cause the fallopian tubes to be narrower than normal may result in:
Implantation of a fertilized ovum within the tube.
More rapid propulsion of the ovum through the tube.
Increased likelihood of pregnancy during each cycle.
Excessive cramping and bleeding during menstruation .
combination birth control pills contain estrogen and progestin. A typical pill packet contains 3 weeks of active hormones and 1 week of placebo pills. During the week of placebo pills, menstruation occurs.
Use your knowledge of the hormonol control of the female reproductive system to:
1) Explain how the pills alter the feedback pathways of FSH and LH to prevent pregnancy.
2) Explain why menstruation occurs during the placebo week

- 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_forwardWhen investigating fertility concerns, a common course of action is to rule out sperm cell-related causes of infertility first since obtaining the relevant specimens is generally less invasive. Sperm number and motility are typically the first parameters assessed in a semen sample. Vitality is another commonly assessed parameter, particularly when motility is deemed poor since it allows physicians to differentiate between live non-motile sperm and dead sperm cells. The procedure for determining vitality is to place sperm in a hypotonic solution and observe the specimen under the microscope after a 5-minute incubation. This short incubation time allows for observable cellular changes without causing cell death. What type of microscope would you recommend using to observe sperm cells for this laboratory test and why?arrow_forwardWhen investigating fertility concerns, a common course of action is to rule out sperm cell-related causes of infertility first since obtaining the relevant specimens is generally less invasive.

- Which of the following mechanisms best explains the contraceptive effect of birth control pills that contain both synthetic estrogen and progestin? Inhibition of ovulation Impairment of implantation hyperplastic changes of the endometrium Production of uterine secretions that are toxic to developing embryos Impairment of sperm transport due to uterotubal obstruction Direct inhibition of oocyte maturationarrow_forwardAn average-weight woman without insurance coverage had unprotected sex and wants to avoid pregnancy. Describe the mechanism of action, pros, cons, and reliability of three different emergency contraception methods and make a recommendation for her specific situation.arrow_forwardSome couple practice natural family planning (also known as the rhythm method of birth control), which involves abstaining from sexual intercourse during the time that a woman can become pregnant in her menstrual cycle. 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

Group of answer choices -True -Falsearrow_forwardJack and Gill are married couples with three children . The couple consulted a family planning clinic . As the nurse manning the clinic you counselled the couple regarding family planning . Jack asks the nurse about vasectomy . He understands that this is a minor operation and asks if he'll become sterile immediately . The nurse's best response is: “No you'll remain fertile ." It may takes several weeks and as many as 30 to 40 ejaculations to remove all the live sperm." You'll be sterile in 2 to 3 days ."
