Summary Introduction
Introduction:
Some couples are not able to conceive due to conditions that impair fertility. A couple is considered infertile if they fail to conceive even after trying for a year. Such couples can be helped by various methods such as artificial reproductive technologies (ARTs). This term refers to all techniques, in which both sperm and eggs are handled outside the body. ART techniques are the favorite method for couples, who are unable to conceive because the female’s oviducts are blocked/damaged due to some reason such as the scarring of the oviduct due to a prior pelvic inflammatory disease (PID).

Students have asked these similar questions
Which of the following is not a mechanism on how contraceptive pills work to prevent pregnancy?
A.
thinning the endometrium to prevent implantation
B.
inhibition of follicular development and suppression of ovulation
C.
progesterone inhibits the sperm from penetrating through the cervix and female upper tract by making the cervical mucus unfriendly
D.
stimulates the production of high testosterone levels
Which of the following is the best explanation for the mechanism, of the action of the intrauterine device (IUD)?
A. Hyperperistalsis of the fallopian tubes accelerates oocyte transport and prevents
fertilization
B. A sub-acute or chronic bacterial endometritis interferes with implantation
C. Premature endometrial sloughing associated with menorrhagia causes early abortion
D. A sterile inflammatory response of the ometrium prevents implantation
E. Cervical mucus is rendered impenetrable to migrating sperm
How do tubal ligations and vasectomies prevent further pregnancies?
Select one:
a. The corpus luteum and the epididymis are suppressed using a chemical swab. The fertilized egg could no longer implant in the endometrium.
b. The Fallopian tubes and vas deferens are cut and tied off, thereby preventing the movement of the eggs and sperm.
c. The Fallopian tubes and the vas deferens are cut. Eggs and sperm can no longer be produced.
d. The Fallopian tube and vas deferens are cut and tied off, thereby reducing needed reproductive hormone levels.

- Superovulation is when women take hormones in order to release more eggs for fertilization. Which of the following rows contains hormones that are involved in developing the follicles and releasing them from the ovary, respectively? What could be the unintended consequence of this process? Select one: a. Hormone Unintended Consequence FSH and LH The formation of twins or multiple births b. Hormone Unintended Consequence FSH and LH A tubal ligation c. Hormone Unintended Consequence FSH and LH Scar tissue on the Fallopian tubes d. Hormone Unintended Consequence LH and FSH Ovarian Cancerarrow_forwardDetermine the pathway of sperm. A. Seminal vesicles → vas deferens → testes → prostate gland →bulbourethral glands → urethra B. Vas deferens → testes → seminal vesicles → prostate gland →bulbourethral glands → urethra C. Testes → seminal vesicles → vas deferens → prostate gland -bulbourethral glands → urethra D. Testes → vas deferens → seminal vesicles → prostate gland -bulbourethral glands → urethra Identify the variation of chromosome structure that is excised and rotated 180 degree within the same chromosome. A. Duplication B. Inversion C. Nondisjunction D. Non-rotationarrow_forwardHow can PID (pelvic inflammatory disease) lead to infertility in women? Select one: a. PID can lead to scar tissue developing on the Fallopian tube. This prevents the egg and the sperm from meeting, causing infertility. b. PID prevents the endometrium from forming. There is not enough material for the fertilized egg to implant itself. c. PID leads to scar tissue on the corpus luteum. This disrupts ovulation. d. PID affects the cervix. This causes the cervix to swell, decreasing the chance a sperm could pass into the uterus.arrow_forward

What is the purpose of maintaining the corpus luteum? Select one: a. The corpus luteum produces relaxin, which thickens the endometrium. b.
