Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.

- A. HIV / AIDS
- B. Pseudomonas pyogenes
- C. Treponema palladium
- D. Neisseria
Explanation: Syphilis is a sexually transmitted disease caused by the bacterium Treponema pallidum. Hence, option C is correct.
Correct answer: Treponema palladium- A. Metaphase
- B. Prophase
- C. Anaphase
- D. Telophase
Explanation: In the secondary meiotic division (also known as meiosis II), the secondary oocyte proceeds as far as the metaphase stage.
Correct answer: Metaphase- A. Primary spermatoeyte
- B. Secondary spermatocyte
- C. Spermatogonia
- D. Spermatid
Explanation: Spermatids undergo a process called spermiogenesis to differentiate into mature sperm cells (spermatozoa), involving structural changes to…
Correct answer: Spermatid- A. Cervix
- B. Fallopian tube
- C. External genitellia
- D. Vulva
Explanation: The uterus opens into the vagina through the cervix. The cervix is a cylindrical neck of tissue that connects the uterus to the vagina.
Correct answer: Cervix- A. AIDS
- B. Genital herpes
- C. Syphilis
- D. Gonorrhea
Explanation: Treponema pallidum is a bacterium that causes syphilis, a sexually transmitted infection (STI).
Correct answer: Syphilis- A. Seminiferous
- B. Vas deferens
- C. Ejaculatory duct
- D. Urethra
Explanation: The main duct of the male reproductive tract is the vas deferens, also known as the ductus deferens.
Correct answer: Vas deferens- A. Urinogenital duct
- B. Sperm duct
- C. Ejaculatory duct
- D. Vas deferens
Explanation: The urinogenital duct is a term that refers to the passage of urine (from the urinary system) and sperm (from the reproductive system)…
Correct answer: Urinogenital duct- A. Secondary oocyte
- B. Primary oocytes
- C. Infinite oogonia
- D. Few oogonia
Explanation: Oogonia divide mitotically to form primary oocytes. Oogonia are diploid cells that are found in the ovaries of female mammals.
Correct answer: Primary oocytes- A. Oogonia
- B. Primary oocytes
- C. Secondary oocytes
- D. Ova
Explanation: At the time of birth, a female has about 1-2 million primary oocytes in her ovaries.
Correct answer: Primary oocytes- A. Life cycle
- B. Menstrual cycle
- C. Nitrogen cycle
- D. Uterine cycle
Explanation: The menstrual cycle is part of both the ovarian and uterine cycles, but it is not the same thing as either of them.
Correct answer: Menstrual cycle- A. Sperm duct
- B. Epididymal tubules
- C. Ejaculatory duct
- D. Urethra
Explanation: The proximal part of the vas deferens, also known as the epididymis, forms highly convoluted structures called epididymal tubules.
Correct answer: Epididymal tubules- A. 4 and 16
- B. 4 and 8
- C. 8 and 16
- D. 32 and 16
Explanation: In spermatogenesis, each meiosis cycle produces 4 spermatids. To form 32 spermatids, 8 meiosis cycles are required.
Correct answer: 8 and 16- A. Organic diseases
- B. Genetic diseases
- C. Sexually transmitted diseases
- D. Congenital diseases
Explanation: Sexually transmitted diseases (STDs), also referred to as sexually transmitted infections (STIs), are infections that can be spread…
Correct answer: Sexually transmitted diseases- A. Zona pellucida
- B. Corona radiata
- C. Chorioallantois
- D. Amnion
Explanation: The outermost layer of a newly ovulated ovum is called the corona radiata.
Correct answer: Corona radiata- A. Maturation of follicle
- B. Formation of early corpus Iuteum
- C. Regression of corpus luteum
- D. Development of follicle
Explanation: Ovulation occurs before the luteal phase of the ovarian cycle.The ovarian cycle is a monthly cycle that prepares the body for pregnancy.
Correct answer: Formation of early corpus Iuteum- A. Cowper's gland
- B. Sertoli cells
- C. Seminal vesicle
- D. Leydig Cells
Explanation: The secretion of the Sertoli cells in the seminiferous tubules of the testes converts spermatids into sperm.The Sertoli cells are a type…
Correct answer: Sertoli cells- A. Seminiferous tubules
- B. Prostate gland
- C. Interstitial cells
- D. Vas deferens
Explanation: Seminiferous tubules are tiny, coiled tubes found in the testes.They are the site of sperm production.Each testis contains about 800…
Correct answer: Seminiferous tubules- A. Seminiferous tubules
- B. Epididymis
- C. Vas deferens
- D. Seminal vesicles
Explanation: Mature sperms are stored in the epididymis. The epididymis is a long, coiled tube that is attached to the back of each testis.
Correct answer: Epididymis- A. Follicle
- B. Interstitial cells
- C. Endometrium
- D. Oviduct
Explanation: When a mature egg leaves the ovary, it enters the fallopian tube. The fallopian tubes are two long, thin tubes that extend from the…
Correct answer: Oviduct- A. Bladder
- B. Uterus
- C. Vagina
- D. Oviduct
Explanation: The endometrium is the lining of the uterus. It is a layer of tissue that is rich in blood vessels and glands.
