MCQs on Reproductive System of Human

Que-1: The male accessory gland whose secretion neutralizes the acidity of the urethra and vagina is:

1. Seminal vesicle
2. Prostate gland
3. Seminiferous tubule
4. Bulbo-urethral gland

Ans: Prostate gland
Hint: The prostate gland produces an alkaline fluid that helps neutralize the acidity of the urethra and vagina.

Que-2: The onset of menstruation in women is called ;

1. Parturition
2. Menopause
3. Ovulation
4. Menarche

Ans: Menarche
Hint: The term used for onset of menstruation in young female is called Menarche.

Que-3: In the human menstrual cycle, the ovulation occurs around :

1. 7 days
2. 21 days
3. 28 days
4. 14 days

Ans: 14 days
Hint: Ovulation occurs during mid-menstrual cycle.

Que-4: Fertilization takes place in :

1. Fallopian tube
2. Uterus
3. Vas deferens
4. Vagina

Ans: Fallopian tube
Hint: Fertilization occurs in the oviduct, also known as the Fallopian tube.

Que-5: The packing tissues between the coils of the seminiferous tubules are called as :

1. Leydig cells
2. Hymen
3. Graafian follicle
4. Clitoris

Ans: Leydig cells
Hint: The tissues found between the coils of the seminiferous tubules are called interstitial cells or Leydig cells.

Que-6: Which of the following cannot pass readily through the placenta to the foetus ?

1. Antibodies
2. Amino acids
3. Alcohol
4. Hemoglobin

Ans: Hemoglobin
Hint: The mother and foetus exchange substances through capillaries, but their blood does not mix, so haemoglobin is not exchanged.

Que-7: The thin-walled sac of skin in which testis descends is :

1. Seminal vesicle
2. Vas deferens
3. Scrotal sac
4. Epididymis

Ans: Scrotal sac
Hint: Testis descends into scrotal sac.

Que-8: The outermost layer of uterine wall around the foetus is :

1. Choroid
2. Allantois
3. Chorion
4. Amnion

Ans: Chorion
Hint: The outermost layer of uterine wall around the foetus is chorion.

Que-9: The period of pregnancy is called :

1. Parturition
2. Implantation
3. Copulation
4. Gestation

Ans: Gestation
Hint: The time from fertilization to the birth of the baby is called the gestation period, and in humans, it lasts about 280 days.

Que-10: The canal through which each testis descends into the scrotum just before the birth of a male baby is :

1. Acrosome
2. Epididymis
3. Efferent duct
4. Inguinal canal

Ans: Inguinal canal
Hint: Each testis moves down into the scrotum before birth through a passage called the inguinal canal.

Assertion and Reason Type Questions on Reproductive System of Human with Solutions / Answer

Que-11: 

Assertion. The placenta is a vital organ during pregnancy, responsible for providing nutrients and oxygen to the developing foetus.
Reason. The placenta develops from the fusion of the zygote and the endometrial lining, forming a specialized tissue structure that facilitates the exchange of substances between the maternal and foetal bloodstreams.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: Both A and R are True.
Explain: The placenta starts forming from the blastocyst soon after it implants, and it stays connected to the fetus through the umbilical cord.

Que-12: 

Assertion. Leydig cells produce oestrogen and progesterone.
Reason. Leydig cells are also called as interstitial cells which are located as packing tissues between the coils of seminiferous tubules.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: A is False and R is True.
Explain: Leydig cells, also known as interstitial cells, primarily produce testosterone, not oestrogen and progesterone. Oestrogen and progesterone are mainly produced by the ovaries in females.

Que-13: 

Assertion. Prostate gland pours an alkaline secretion which neutralizes the acidic pH of the vagina.
Reason. Prostate gland is a lobulated gland located between the posterior surface of the urinary bladder and the rectum.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: A is True and R is False.
Explain:  The prostate gland is a two-lobed gland situated below the urinary bladder and it encircles the urethra.

Que-14: 

Assertion. Fertilization of the ovum and sperm occurs in the sperm duct of the female reproductive system.
Reason. Vas deferens carries sperms from the epididymis to the urethra of the male reproductive system.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: A is False and R is True.
Explain:  Fertilization of the egg by the sperm takes place in the fallopian tube.
