1. Question
Which of the following is true?
IncorrectAnswer:
The male gametes are called sperm and contain a half set of chromosomes.
Male gametes, or sperm, are haploid cells, meaning they contain half the normal number of chromosomes (23 in humans). This is essential for sexual reproduction, as fertilization combines the sperm’s 23 chromosomes with the 23 chromosomes from the female gamete (ova) to form a zygote with a full set of 46 chromosomes.
The female gametes are called ova and contain a full set of chromosomes is incorrect. Ova (singular: ovum) are indeed the female gametes, but they contain half of a set of chromosomes, not a full set. This is because they are meant to combine with a male gamete, which also contains half a set of chromosomes, to form a zygote with a full set of chromosomes.
The female gametes are called ovaries and contain half of a set of chromosomes is incorrect. The ovaries are the female reproductive organs that produce ova, but they are not gametes themselves. Ova are the gametes produced by the ovaries.
The male gametes are called eggs and contain a full set of chromosomes is incorrect. Eggs are not male gametes; they are female gametes (ova). Male gametes are called sperm, and like ova, they contain half of a set of chromosomes.2. Question
Which of the following structures is correctly paired with its description?
IncorrectAnswer:
Prostate gland/ secretion of fluid that contributes to sperm motility and viability
The prostate gland secretes a fluid that is a component of semen. This fluid contains enzymes and nutrients that enhance sperm motility and viability, aiding in successful reproduction.
Seminal vesicle/ transports sperm from epididymis to urethra: The seminal vesicles do not transport sperm; they produce a fructose-rich fluid that nourishes the sperm. The vas deferens is the structure that transports sperm from the epididymis to the urethra.
Urethra/ temporarily store the sperm: The urethra is a tube that transports urine and semen out of the body in males. Sperm is stored in the epididymis, not the urethra.
Vas deferens/ transports urine in both male and female and semen in male: The vas deferens transports sperm, not urine, and is present only in males. Urine and semen are transported through the urethra in males.
Please see the diagram below as a visual reference for the anatomy of the reproductive system referenced in the question above.

Which of the following is not true about reproductive hormones?
CorrectAnswer:
LH (luteinizing hormone) is produced by the posterior pituitary gland.
LH (luteinizing hormone) is produced by the anterior pituitary gland, not the posterior pituitary gland. The anterior pituitary secretes both LH and FSH, which are critical for regulating reproductive processes.FSH (follicle-stimulating hormone) is produced by the anterior pituitary gland is true. FSH is secreted by the anterior pituitary and is involved in the development of follicles in the ovaries and the maturation of sperm in the testes.
FSH (follicle-stimulating hormone) stimulates maturation of sperm and ovum is true. FSH promotes the maturation of ovarian follicles in females and supports spermatogenesis in males.
LH (luteinizing hormone) stimulates ovulation and production of testosterone is true. In females, LH triggers ovulation and stimulates the corpus luteum to produce progesterone. In males, LH stimulates the Leydig cells in the testes to produce testosterone.
4. Question
Which of the following structures is responsible for the transport of female gametes?
CorrectAnswer:
Fallopian tube
The fallopian tube (also called the uterine tube or oviduct) is responsible for transporting female gametes (ova) from the ovary to the uterus. It is also the site where fertilization typically occurs.
The urethra is a tube that carries urine from the bladder to the outside of the body in both males and females. It is not involved in the transport of gametes.
The vas deferens is a male reproductive structure that transports sperm from the epididymis to the ejaculatory ducts.
The cervix is the lower part of the uterus that connects the uterus to the vagina. It does not transport gametes; instead, it acts as a passageway during childbirth and for menstrual flow.
5. Question
Which of the following is responsible for producing progesterone in preparation for pregnancy?
CorrectAnswer:
Corpus luteum
The corpus luteum, which forms from the follicle after ovulation, is responsible for producing progesterone. This hormone prepares the uterus for pregnancy by thickening the endometrial lining to support implantation and sustain early pregnancy.
The uterus is the site where the fertilized egg implants and grows during pregnancy, but it does not produce progesterone.
The cervix is the lower part of the uterus that connects to the vagina. It plays a role in allowing or blocking the passage of sperm but does not produce hormones.
The pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which regulate ovulation and the formation of the corpus luteum, but it does not produce progesterone directly.
6. Question
Which of the following organs is correctly paired with the hormone it produces?
IncorrectAnswer:
Ovaries/ estrogen
The ovaries produce estrogen, a hormone responsible for the development of female secondary sexual characteristics and the regulation of the menstrual cycle.
Adrenal gland/ vasopressin: Vasopressin (antidiuretic hormone or ADH) is produced by the hypothalamus and stored in the posterior pituitary gland. The adrenal glands produce hormones such as cortisol, aldosterone, and adrenaline.
Mammary gland/ prolactin: Prolactin is produced by the anterior pituitary gland, not the mammary glands. Prolactin stimulates milk production in the mammary glands.
Anterior pituitary gland/ oxytocin: Oxytocin is produced by the hypothalamus and stored in the posterior pituitary gland, not the anterior pituitary gland.

7. Question
Which of the following structures is the female gonads?
CorrectAnswer:
Ovaries
The ovaries are the female gonads. They are responsible for producing female gametes (ova or eggs) and secreting hormones such as estrogen and progesterone, which are essential for reproduction and the menstrual cycle.
The uterus functions as the implantation site of a fertilized ovum and serves as the pathway for sperm to reach the fallopian tubes.
The cervix is the narrow entrance to the uterus.
The vagina is the female copulatory organ that also serves as the outlet for menstrual flow and the passageway for childbirth.Please see the diagram below as a visual reference for the anatomy of the female reproductive system referenced in the question above.
8. Question
Which of the following parts of the male reproductive system is not correctly paired with its function?
IncorrectAnswer:
Epididymis/ secretes mucus that lubricates the urethra
The epididymis does not secrete mucus. Its primary function is to store and mature sperm after they are produced in the testes. The structure responsible for secreting mucus to lubricate the urethra is the bulbourethral glands (Cowper’s glands).
The penis serves as a conduit for semen during ejaculation and for urine during excretion.
The testes are the site for production of male gametes while the epididymis is where the maturation of male gametes (sperm) takes place. The sperm are transported to and stored in the epididymis, where they mature, and then travel to the vas deferens upon arousal.
The Scrotum is the pouch of skin that encloses and supports the testes and penis serves as passageway for semen and urine.Please see the diagram below as a visual reference for the anatomy of the male reproductive system referenced in the question above.
9. Question
Which of the following glands are not found in both males and females?
CorrectAnswer:
Cowper’s gland
The Cowper’s glands (also known as bulbourethral glands) are exclusive to males. They secrete a clear mucus-like fluid that lubricates the urethra and neutralizes traces of acidic urine prior to ejaculation. They are found on the lateral side of the male urethra.
Adrenal glands: These are present in both males and females. They are located above the kidneys and produce hormones like cortisol, adrenaline, and aldosterone.
Pituitary gland: This gland is found in both males and females. It is located at the base of the brain and regulates various hormones that control growth, reproduction, and metabolism.
Parathyroid glands: These are present in both males and females. They are located on the posterior surface of the thyroid gland and regulate calcium levels in the blood.
10. Question
Which of the following is the process by which gametes divide and produce half the number of chromosomes found in a somatic cell?
CorrectAnswer:
Meiosis
Meiosis is the process by which gametes (sperm and ova) are formed. During meiosis, a diploid cell (containing a full set of chromosomes) divides twice to produce four haploid cells, each with half the number of chromosomes found in a somatic cell. This ensures that when fertilization occurs, the resulting zygote has the correct diploid number of chromosomes.
Fertilization: This is the process in which a sperm and an ovum fuse to form a zygote, restoring the diploid chromosome number.
Gametes: These are the cells (sperm in males and ova in females) that result from meiosis, but this term does not describe the process of their formation.
Zygote: This is the single-cell result of the fusion of male and female gametes during fertilization. It is diploid and will undergo mitosis to develop into a multicellular organism.
11. Question
Which of the following organs functions as both the implantation site of a fertilized ovum and the pathway for sperm to reach the uterine tubes?
CorrectAnswer:
Uterus
The uterus functions as both the implantation site of a fertilized ovum and as the pathway for sperm to reach the uterine tubes.
The fallopian tubes serve as the passageway for an ovum from the ovaries and is the site of fertilization.
The vagina is the female copulatory organ that also serves as the outlet for menstrual flow and the passageway for childbirth.
The cervix is the inferior narrow portion of the uterus where sperm capacitation occurs prior to fertilization.Please see the diagram below as a visual reference for the anatomy of the female reproductive system referenced in the question above.
12. Question
Which of the following is not a part of the male reproductive system?
CorrectAnswer:
Bladder
The bladder serves as a temporary reservoir for urine and is part of the urinary system.
The urethra serves as a passageway for sperm in males.
The Bulbourethral glands (or Cowper’s glands) secrete mucus that lubricates the urethra.
The epididymis is where sperm are stored until male arousal.Please see the diagram below as a visual reference for the anatomy of the male reproductive system referenced in the question above.
13. Question
Match the following structures to their function.
Drag and drop tiles in the appropriate box.
Sort elements
CorrectThe implantation site of a fertilized egg, or zygote, is the uterus.
The Vas deferens is the sperm channel from the epididymis to the penis.
The penis is the external sexual organ of a male.
The vagina is the copulatory organ of a female.
The sperm enters the female’s body in the vagina and moves through the cervix to reach the uterus, then finally the fallopian tubes.
Fertilization takes place in the fallopian tube. After fertilization, the zygote moves from the fallopian tube to the uterus where it implants.14. Question
Which of the following statements is correct?
CorrectAnswer:
Gonads produce sperm in males and ova in females.
The gonads are the primary reproductive organs that produce gametes. In males, the gonads are the testes, which produce sperm. In females, the gonads are the ovaries, which produce ova (eggs).
The male gonads are the testes and the penis is incorrect.The male gonads are the testes, which produce sperm. The penis is the external sex organ, not a gonad.
The female gonads are the uterus and the ovaries is incorrect. The female gonads are the ovaries, which produce ova. The uterus is the organ where the fertilized egg implants and develops, but it is not a gonad.
Gonads, similar to other organs, produce cells that have the full number of chromosomes is incorrect. Gonads produce gametes (sperm and ova), which are haploid cells, meaning they contain half the number of chromosomes (23 in humans). Only somatic cells have the full set of chromosomes (46 in humans).
15. Question
Function of male and female reproductive system is regulated by hormones. Which of the following is not correct?
CorrectAnswer:
The Cowper’s glands produce testosterone.
The Cowper’s glands (also known as bulbourethral glands) do not produce testosterone. They secrete a clear, mucus-like fluid that helps to lubricate the urethra and neutralize traces of acidic urine before ejaculation. Testosterone is primarily produced in the testes in males.
The corpus luteum is a temporary structure in the ovary that forms after ovulation and secretes progesterone to help prepare the uterus for potential pregnancy.
The pituitary gland, located in the brain, secretes both FSH and LH, which regulate the reproductive processes in both males and females.
Testosterone, produced primarily in the testes, is responsible for the development of male secondary sexual characteristics such as facial hair, deeper voice, and increased muscle mass.
