Human Reproduction and Contraception Questions

Multiple choice biology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

The persistence of corpus luteum during pregnancy is due to a hormone known as

  1. Chorionic gonadotropic hormone

  2. FSH

  3. Estrogen

  4. Progesterone

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Human chorionic gonadotrophin is the embryonic hormone, which ensures the corpus luteum continues to produce progesterone throughout the first trimester of pregnancy. The corpus luteum continues to produce progesterone until the placenta is established (the placenta then takes over progesterone production).

Most of the contraceptive pills contain

  1. Estrogen and FSH

  2. Progesterone and LH

  3. FSH and LH

  4. Oestrogen and progesterone

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Most birth control pills are combination pills containing a combination of the hormones oestrogen and progesterone to prevent ovulation. A woman cannot get pregnant if she doesn't ovulate because there is no egg to be fertilized. The pill also works by thickening the mucus around the cervix, which makes it difficult for sperm to enter the uterus and reach any eggs that may have been released. The hormones in the pill can also sometimes affect the lining of the uterus, making it difficult for an egg to attach to the wall of the uterus.

Immediate cause of induction of ovulation in human female, is surge of

  1. Progesterone

  2. LH

  3. FSH

  4. Estradiol

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

FSH is primarily involved in stimulating the growth of ovarian follicles, while LH induces ovulation. At ovulation, the ovum or egg is released and the ruptured follicle is transformed into a corpus luteum, which secretes progesterone as its main product.

Ovulation in mammals occurs mainly under the influence of 

  1. TSH and ACTH

  2. FSH and LH

  3. TSH and STH

  4. MTH and ACTH

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Gonadotropin-releasing hormone (GnRH) is secreted by the hypothalamus and stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. 

FSH initiates follicular growth and the secretion of estrogens by the growth follicles. 
LH stimulates the further development of ovarian follicles and their full secretion of estrogens, brings about ovulation, promotes the formation of the corpus luteum and stimulates the production of estrogens, progesterone, relaxin and inhibin by the corpus luteum.

Which temporary endocrine gland forms in ovary after ovulation? 

  1. Corpus callosum

  2. Corpus albicans

  3. Corpus luteum

  4. Corpus striata

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The corpus luteum is a temporary endocrine structure in female mammals, that is involved in the production of progesterone and moderate levels of estradiol and inhibin. The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation. 

Multiple choice
  1. Tubectomy

  2. Vasectomy

  3. Parthenocarpy

  4. Peristalsis

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tubectomy is a surgical sterilization method for females where the fallopian tubes are cut or blocked to prevent eggs from reaching the uterus. Vasectomy is the corresponding surgical method for males, while parthenocarpy and peristalsis are unrelated biological processes.
