    This hormone promotes spermatogenesis.

    • Relaxin

    • Testosterone

    • Inhibin

    • Estrogen

    • Aldosterone

    Correct Answer
    A. Testosterone
    Explanation
    Testosterone is the correct answer because it is a hormone that plays a crucial role in promoting spermatogenesis, which is the process of sperm production in males. Testosterone is primarily produced in the testes and is responsible for the development and maintenance of male reproductive tissues, including the testes and prostate. It stimulates the production of sperm cells and supports their maturation. Additionally, testosterone is involved in the development of secondary sexual characteristics in males, such as the deepening of the voice and the growth of facial and body hair.

    These cells may eventually become spermatozoa

    • Sertoli cells

    • Sustentacular cells

    • Spermatogenic cells

    • Chief cells

    • Speciation cells

    Correct Answer
    A. Spermatogenic cells
    Explanation
    Spermatogenic cells are responsible for the production of spermatozoa, the mature male reproductive cells. These cells undergo a process called spermatogenesis, which involves multiple stages of cell division and differentiation. As the spermatogenic cells mature, they develop into spermatozoa that are capable of fertilizing an egg. Therefore, it is logical to say that these cells may eventually become spermatozoa.

    Rate this question:

  • 5. 

    This is the site of fertilization.

    • Ureters

    • Urethra

    • Uterine tubes

    • Ovaries

    • Vagina

    Correct Answer
    A. Uterine tubes
    Explanation
    The uterine tubes, also known as fallopian tubes, are the site of fertilization in the female reproductive system. These tubes connect the ovaries to the uterus and play a crucial role in the process of conception. During ovulation, an egg is released from the ovary and travels through the uterine tube. If sperm is present in the tube, fertilization can occur as the sperm meets the egg. The fertilized egg then continues its journey towards the uterus for implantation. Therefore, the uterine tubes are responsible for facilitating the meeting of sperm and egg, making them the site of fertilization.

    Rate this question:

  • 6. 

    This structure is the site of sperm production

    • Vas deferens

    • Seminiferous tubules

    • Albuginea

    • Epididymis

    • Raphe

    Correct Answer
    A. Seminiferous tubules
    Explanation
    The seminiferous tubules are the site of sperm production in the male reproductive system. These tubules are located within the testes and are responsible for producing and maturing sperm cells. Sperm production occurs through a process called spermatogenesis, which involves the division and differentiation of germ cells within the seminiferous tubules. Once produced, the sperm cells are then transported to the epididymis for further maturation and storage before ejaculation. Therefore, the seminiferous tubules play a crucial role in the production of sperm and are essential for male fertility.

    Rate this question:

  • 7. 

    This is composed of three cylindrical masses of erectile tissue each surrounded by a fibrous tissue.

    • Testes

    • Prostate

    • Bladder

    • Penis

    • Urethra

    Correct Answer
    A. Penis
    Explanation
    The correct answer is Penis. The penis is composed of three cylindrical masses of erectile tissue, namely the two corpora cavernosa and the corpus spongiosum, which are surrounded by a fibrous tissue. These erectile tissues fill with blood during sexual arousal, causing the penis to become erect. The penis also contains the urethra, which is the tube through which urine and semen pass. The testes produce sperm, the prostate gland secretes fluid that nourishes and protects sperm, and the bladder stores urine, but they are not composed of three cylindrical masses of erectile tissue surrounded by fibrous tissue like the penis.

    Rate this question:

    The fuction of the epididymis is

    • Sperm maturation

    • Produce sperm

    • Speratid storage

    • Provide nutrition to sperm

    • Absorption of calcium

    Correct Answer
    A. Sperm maturation
    Explanation
    The epididymis is responsible for the maturation of sperm. It provides the environment necessary for sperm to develop and acquire motility. Sperm produced in the testes are immature and incapable of fertilizing an egg. As they pass through the epididymis, they undergo a process called sperm maturation, where they gain the ability to swim and fertilize an egg. Therefore, the correct answer is "Sperm maturation."

    • Tertiary oocytes, insulin and estrogen

    • Secondary oocytes, estrogen and progesterone

    • Primary oocytes, estrogen and testosterone

    Correct Answer
    A. Secondary oocytes, estrogen and progesterone
    Explanation
    The correct answer is secondary oocytes, estrogen, and progesterone. The ovaries are responsible for producing and releasing eggs, which are called oocytes. These oocytes develop into secondary oocytes, which can be fertilized by sperm. The ovaries also produce the hormones estrogen and progesterone, which play important roles in regulating the menstrual cycle and preparing the uterus for pregnancy.

    Rate this question:

  • 11. 

    This is secreted by the corpus luteum after ovulation.

    • Progesterone

    • Relaxin

    • LH

    • FSH

    • HGH

    Correct Answer
    A. Progesterone
    Explanation
    Progesterone is a hormone secreted by the corpus luteum, which is formed after ovulation. It plays a crucial role in preparing the uterus for pregnancy and maintaining pregnancy if it occurs. Progesterone helps to thicken the uterine lining, making it suitable for implantation of a fertilized egg. It also helps to inhibit contractions of the uterus, preventing premature labor. Therefore, the secretion of progesterone by the corpus luteum after ovulation is essential for supporting and sustaining a potential pregnancy.

    Rate this question:

  • 12. 

    This structure protects and regulates the temperature of the testes

    • Dartos muscle

    • Cremaster muscle

    • Tunica albuginea

    • Scrotum

    • Tunica vaginalis

    Correct Answer
    A. Scrotum
    Explanation
    The scrotum is a pouch of skin that houses the testes. It is located outside the body in the male reproductive system. The scrotum plays a crucial role in protecting and regulating the temperature of the testes. The testes need to be kept at a slightly lower temperature than the rest of the body for optimal sperm production. The scrotum contracts and relaxes in response to temperature changes, bringing the testes closer to or further away from the body to maintain the right temperature. This mechanism is essential for the proper functioning of the testes and the production of healthy sperm.
