Human Reproduction NEET Questions With Solutions

Human Reproduction NEET Questions: The chapter on Human Reproduction carries a lot of importance in the NEET Biology syllabus, as it tends to carry several direct and concept-based questions every year. Being a major component of the Human Physiology topic, the chapter discusses male and female reproductive systems, gametogenesis, fertilization, menstrual cycle, pregnancy, embryonic development, and parturition. These topics are not only essential for scoring well but also help in understanding chapters like Reproductive Health and Genetics & Evolution. NEET often includes both diagram-based and factual questions from this chapter, making it important to focus on both concept clarity and memory-based facts. In this article, we’ll cover the key concepts, important diagrams, and tips to master Human Reproduction for better performance in the NEET examination.

Human Reproduction Some Previous Year Questions with solutions

Question 1: Which of the following is not a component of the Fallopian tube? (NEET 2024)

1. Uterine fundus

2. Isthmus

3. Infundibulum

4. Ampulla

Solution: The correct answer is option (1), as the uterine fundus is the upper, dome-shaped part of the uterus above the opening of the fallopian tubes.
Option (2) is incorrect as the isthmus is the last and narrow part of the oviduct that links to the uterus.
Option (3) is incorrect, as the infundibulum is the part of the oviduct that is closer to the ovary.
Option (4) is incorrect as the ampulla is the wider part of the oviduct.

Hence, the correct answer is option 1) Uterine fundus.

Question 2: Given below are two statements: One is labeled as Assertion A, and the other is labeled as Reason R: (Re-NEET 2024)

Assertion A: FSH acts upon ovarian follicles in females and Leydig cells in males.

Reason R: Growing ovarian follicles secrete estrogen in females, while interstitial cells secrete androgen in male human beings.

In the light of the above statements, choose the correct answer from the options given below:

1. Both A and R are true, and R is the correct explanation of A

2. Both A and R are true, but R is NOT the correct explanation of A

3. A is true, but R is false

4. A is false, but R is true

Solution: The assertion that FSH influences the ovarian follicles in females but LH affects the Leydig cells in males is correct. While FSH increases the growth of ovarian follicles and secretion of estrogen, it is LH that stimulates the androgen production in Leydig cells in males. Thus, the assertion is incorrect, and the reason is true.

Hence, the correct answer is option 4) A is false, but R is true.

Question 3: Given below are two statements:

Statement I: The presence or absence of the hymen is not a reliable indicator of virginity.

Statement II: The hymen is torn during the first coitus only.

In the light of the above statements, choose the correct answer from the options given below: (NEET 2024)

1. Both Statement I and Statement II are true

2. Both Statement I and Statement II are false

3. Statement I is true, but Statement II is false

4. Statement I is false, but Statement II is true

Solution: The presence or absence of a hymen is not a reliable indicator of virginity because the hymen can also be broken by a sudden jolt, insertion of a vaginal tampon,
Active participation in some sports, and for some women, the hymen persists even after coitus.

Hence, the correct option is 3) Statement I is true, but Statement II is false.

Question 4: Given below are two statements: One is labelled as Assertion A, and the other is labelled as Reason R:

Assertion A: Breastfeeding during the initial period of infant growth is recommended by doctors for bringing a healthy baby.

Reason R: Colostrum contains several antibodies essential to developing resistance for the newborn baby.

In the light of the above statements, choose the most appropriate answer from the options given below: (NEET 2024)

1. Both A and R are correct, and R is the correct explanation of A

2. Both A and R are correct, but R is NOT the correct explanation of A

3. A is correct, but R is not correct

4. A is not correct, but R is correct

Solution: Health professionals greatly recommend breastfeeding the infant to be fed in the earliest period of child growth. After birth, babies produce colostrum-containing antibodies, an essential factor involved in the early development of immune systems. For the protection and general health care of infants before infections set off, early nutrition during the early time of a child's life is the most important starting point.

Hence, the correct answer is option 1) Both A and R are correct, and R is the correct explanation of A.

Question 5: Identify the correct option (A), (B), (C), (D) concerning spermatogenesis.

1. FSH, Leydig cells, Sertoli cells, spermiogenesis.

2. ICSH, Interstitial cells, Leydig cells, spermiogenesis.

3. FSH, Sertoli cells, Leydig cells, spermatogenesis.

4. ICSH, Leydig cells, Sertoli cells, spermatogenesis. (NEET 2024)

Solution:

(A) FSH, which is a pituitary hormone.
(B) Leydig cells, which are found in the interstitial space outside of the seminiferous tubules.
(C) Sertoli cells are found inside the seminiferous tubules.
(D) Spermiogenesis, which is a process that helps in the transformation of spermatids into spermatozoa.

Hence, the correct answer is option 1) as FSH, Leydig cells, Sertoli cells, and spermiogenesis.

Question 6: Given below are two statements:

Statement I: The Vas deferens receive a duct from the seminal vesicle and opens into the urethra as the ejaculatory duct.

Statement II: The cavity of the cervix is called the cervical canal which along with the vagina' forms the birth canal.

In the light of the above statements, choose the correct answer from the options given below: (NEET 2023)

1. Both Statement I and Statement II are true.

2. Both Statement I and Statement II are false.

3. Statement I is correct, but Statement II is false.

4. Statement I is incorrect, but Statement II is true.

Solution:

Statement I: The vas deferens is a tube that receives a duct from the seminal vesicle and carries sperm from the epididymis to the urethra. It is a part of the male reproductive system and is involved in the transportation of sperm during ejaculation.

Statement II: The cervix is the lower part of the uterus that connects the uterus to the vagina. It contains a cavity called the cervical canal, which is a passageway for sperm to enter the uterus and for menstrual blood to exit the uterus during menstruation. The cervix, along with the vagina, forms the birth canal through which a baby passes during childbirth.

Both statements accurately describe anatomical structures and their functions in the male and female reproductive systems, respectively.

Hence, the correct answer is option 1) Both Statement I and Statement II are true.

Question 7: Which of the following statements are correct regarding the female reproductive cycle?

A. In non-primate mammals, cyclical changes during reproduction are called the oestrus cycle.

B. The first menstrual cycle begins at puberty and is called menopause.

C. Lack of menstruation may be indicative of pregnancy.

D. Cyclic menstruation extends between menarche and menopause. (NEET 2023)

Choose the most appropriate answer from the options given below:-

1. A and D only

2. A and B only

3. A, B and C only

4. A, C and D only

Solution: A. In non-primate mammals, cyclical changes during reproduction are indeed called the estrus cycle, not the menstrual cycle. The estrus cycle is characterized by the presence of an estrus phase, during which the female is sexually receptive.

B. The first menstrual cycle in females begins at puberty, marking the onset of reproductive capability. Menopause, on the other hand, refers to the cessation of menstrual cycles and reproductive function in women, typically occurring around the age of 45-55.

C. Lack of menstruation can be indicative of pregnancy. During pregnancy, menstruation ceases due to the hormonal changes that sustain the pregnancy.

D. Cyclic menstruation extends between menarche (the onset of the first menstrual cycle) and menopause (the cessation of menstrual cycles).

Hence, the correct answer is option 4) A, C, and D only.

Question 8: Given below are two statements: one is labelled as Assertion A, and the other is labelled as Reason R.

Assertion A: The Endometrium is necessary for the implantation of a blastocyst.

Reason R: In the absence of fertilization, the corpus luteum degenerates, which causes the disintegration of the endometrium.

In the light of the above statements, choose the correct answer from the options given below: (NEET 2023)

1. Both A and R are true, and R is the correct explanation of A.

2. Both A and R are true, and R is NOT the correct explanation of A.

3. A is true, but R is false.

4. A is true, but R is true.

Solution: The assertion (A) that the endometrium is necessary for implantation of the blastocyst is true. The endometrium provides the necessary environment for the embryo to attach and establish a connection with the maternal blood supply.

The reason (R) provided, stating that the degeneration of the corpus luteum causes the disintegration of the endometrium, is not the correct explanation for the necessity of the endometrium. The degeneration of the corpus luteum and the subsequent decrease in hormone levels contribute to the shedding of the endometrium during menstruation but do not directly explain the requirement of the endometrium for blastocyst implantation.

Hence, the correct answer is option 2) Both A and R are true, and R is NOT the correct explanation of A.

Common Mistakes in Preparing Human Reproduction

Skipping Hormonal Regulation: Most students overlook the significance of hormones. It's necessary to refer to flowcharts and know what each hormone does throughout the menstrual cycle. NEET tends to ask straightforward questions regarding such aspects as the LH surge or the function of progesterone.

Mixing Up Gametogenesis Steps: Spermatogenesis and oogenesis are commonly confused by students. Use straightforward flowcharts to recall that oogenesis gives rise to one ovum and polar bodies, whereas spermatogenesis gives rise to four sperm per cell.

Not Practicing Diagrams: Diagram questions are usual. Practice drawing and labeling the male and female reproductive systems, menstrual cycle phases, and conception steps.

Overlooking Menstrual Cycle Phases: Learn which hormones spike in each phase. For instance, LH jumps at ovulation, and progesterone reaches its peak at the luteal phase.
