Human Reproduction Questions and Answers
- 1.
What reproductive organ(s) of the female secretes fluid for vaginal lubrication during coitus?
- A.
Uterine tubes
- B.
Labia majora
- C.
Vestibular glands
- D.
Pudendal cleft
Correct Answer
C. Vestibular glandsExplanation
The vestibular glands are responsible for secreting fluid for vaginal lubrication during coitus. These glands are located on either side of the vaginal opening and produce mucus-like fluid that helps to reduce friction during sexual intercourse. This lubrication is important for comfortable and pleasurable sexual activity. Uterine tubes, labia majora, and pudendal cleft do not secrete fluid for vaginal lubrication.Rate this question:

During the _________________ phase of menstruation, the lining of the uterus rebuilds.
- A.
Menstrual
- B.
Proliferative
- C.
Secretory
- D.
The lining of the uterus rebuilds continually
Correct Answer
B. ProliferativeExplanation
During the proliferative phase of menstruation, the lining of the uterus rebuilds. This phase occurs after menstruation and is characterized by the growth and thickening of the endometrium (lining of the uterus) in preparation for potential implantation of a fertilized egg. The proliferative phase is driven by estrogen produced by the ovaries, which stimulates the growth of new blood vessels and the regeneration of the endometrial lining. This phase typically occurs in the first half of the menstrual cycle, leading up to ovulation.Rate this question:

During ejaculation, as the sperm pass out of the man's body through the penis, secretions that fuel and protect the sperm are also released from the
- A.
Seminal vesicles and prostate gland
- B.
Androgens and prostate gland
- C.
Prostate gland and urethra
- D.
Seminal vesicles and urethra
Correct Answer
A. Seminal vesicles and prostate glandExplanation
During ejaculation, the seminal vesicles and prostate gland release secretions that fuel and protect the sperm. The seminal vesicles produce a fluid that contains fructose, which provides energy for the sperm. The fluid also contains prostaglandins, which help to stimulate contractions in the female reproductive tract, aiding in the movement of the sperm. The prostate gland produces a milky fluid that helps to neutralize the acidity of the vagina, creating a more favorable environment for the sperm. Together, these secretions from the seminal vesicles and prostate gland support the survival and motility of the sperm during fertilization.Rate this question:

The optimal time for fertilization (conception) to occur within the menstrual (ovarian) cycle is
- A.
At the beginning of the cycle
- B.
At the middle of the cycle
- C.
At the end of the cycle
- D.
Any time during the cycle
Correct Answer
B. At the middle of the cycleExplanation
The optimal time for fertilization to occur within the menstrual cycle is at the middle of the cycle. This is because ovulation, the release of an egg from the ovary, typically occurs around the middle of the cycle. Sperm can survive in the reproductive tract for several days, so having intercourse a few days before ovulation can still result in fertilization. However, the chances of successful fertilization are highest when intercourse occurs around the time of ovulation.Rate this question:

If pregnancy fails to take place, the decreasing level of hormones lead to menstruation, about ____ days after ovulation
- A.
2
- B.
5
- C.
7
- D.
14
Correct Answer
D. 14Explanation
After ovulation, if pregnancy does not occur, the hormone levels in the body start to decrease. This decrease in hormone levels triggers the shedding of the uterine lining, which results in menstruation. It takes about 14 days for this process to occur after ovulation.Rate this question:

Which one of the following statements is incorrect about menstruation?
- A.
The beginning of the cycle of menstruation is called menarche
- B.
During normal menstruation about 40 ml blood is lost
- C.
The menstrual fluid can easily clot
- D.
At menopause in the female, there is especially abrupt increase in gonadotropic hormones
Correct Answer
C. The menstrual fluid can easily clotExplanation
During menstruation, the lining of the uterus is shed and expelled from the body through the vagina. The menstrual fluid consists of blood, tissue, and mucus. It is normal for the menstrual fluid to contain small clots, as the blood may coagulate during the process. However, the statement that the menstrual fluid can easily clot is incorrect. Clotting in the menstrual fluid is typically a sign of a heavier flow or certain medical conditions, and it is not considered normal.Rate this question:

Rete testis open to
- A.
Urethra
- B.
Vasa efferentia
- C.
Bidder’s cannal
- D.
Cauda epididymis
Correct Answer
B. Vasa efferentiaExplanation
The rete testis is a network of tubules located within the testis that connects the seminiferous tubules to the epididymis. The vasa efferentia are small ducts that arise from the rete testis and transport sperm from the testis to the epididymis. Therefore, the vasa efferentia are open to the rete testis, allowing for the passage of sperm.Rate this question:

In which phase of cell division oocytes get arrested?
- A.
Interphase
- B.
Prophase I
- C.
Anaphase II
- D.
Both Anaphase II
Correct Answer
B. PropHase IExplanation
During cell division, oocytes get arrested in the Prophase I phase. Prophase I is the longest phase of meiosis and is characterized by the condensation of chromosomes, pairing of homologous chromosomes, and crossing over between them. This phase is crucial for genetic recombination and ensures the proper segregation of chromosomes during meiosis. Oocytes remain arrested in Prophase I until they are stimulated to continue the division process.Rate this question:

Fertilization in humans takes place in?
- A.
Ampulla of oviduct
- B.
Isthmus of oviduct
- C.
Fimbriae of oviduct
- D.
Both Anaphase II
Correct Answer
A. Ampulla of oviductExplanation
Fertilization in humans takes place in the ampulla of the oviduct. The ampulla is the widest and longest part of the oviduct, located between the isthmus and the infundibulum. It is in the ampulla where the sperm and egg meet and fertilization occurs. The ampulla provides the ideal environment for fertilization to take place, with its ciliated epithelium and secretions that support the movement and survival of sperm. Once fertilization occurs, the resulting embryo will travel through the oviduct towards the uterus for implantation.Rate this question:

A female produces immature ova in her ovaries while developing in her mother's womb. Between puberty and menopause, usually, one ovum per month matures and is released. How many ova ultimately reach maturity?
- A.
40-50
- B.
400-500
- C.
40,000
- D.
400 million
Correct Answer
B. 400-500Explanation
During a female's lifetime, usually one ovum per month matures and is released. Considering the average lifespan of a female, which is around 40-50 years, the number of ova that ultimately reach maturity would be around 400-500.Rate this question:

When the secondary oocyte is released from the ovary, it is surrounded by
- A.
Corpus luteum
- B.
Zona pellucida
- C.
Corona radiata
- D.
B & c only
Correct Answer
D. B & c onlyExplanation
When the secondary oocyte is released from the ovary, it is surrounded by the zona pellucida and the corona radiata. The zona pellucida is a thick layer of glycoproteins that surrounds the oocyte and plays a role in fertilization. The corona radiata is a layer of granulosa cells that surround the oocyte and provide protection and support. The corpus luteum, on the other hand, is formed from the remnants of the ovarian follicle after ovulation and is responsible for producing progesterone to support pregnancy. Therefore, the correct answer is b & c only.Rate this question:
-

What happens during fertilization in humans after many sperm reach close to the ovum?
- A.
Cells of corona radiata trap all the sperms except one
- B.
Only two sperms nearest the ovum penetrate zona pellucid
- C.
Secretions of acrosome (termed the acrosome reaction) help one sperm enter the cytoplasm of the ovum through zona pellucida.
- D.
All sperms except the one nearest to the ovum lose their tails
Correct Answer
C. Secretions of acrosome (termed the acrosome reaction) help one sperm enter the cytoplasm of the ovum through zona pellucida.Explanation
During fertilization in humans, the secretions of the acrosome in the sperm help one sperm enter the cytoplasm of the ovum through the zona pellucida. The acrosome contains enzymes that aid in breaking down the zona pellucida, allowing the sperm to penetrate and fertilize the egg. This process ensures that only one sperm successfully fertilizes the egg, while the other sperm are unable to enter and are trapped or lose their tails.Rate this question:
