- A. Seminal vesicles
- B. Scrotum
- C. Testes
- D. Epididymis
- E. Vasa deferentia
Explanation: The epididymis is a coiled tube located at the back of each testis. Its primary function is to store and mature sperm produced in the…
Correct answer: Epididymis- A. Azoospermia
- B. Obstruction
- C. Oligospermia
- D. Zoospermia
- E. Ejaculation disorder
Explanation: Azoospermia is a medical condition characterized by the absence of sperm in a man's semen.
Correct answer: Azoospermia- A. FSH
- B. ACTH
- C. DHT
- D. LH
- E. TSH
Explanation: Luteinizing Hormone (LH) is a key hormone in the reproductive system. In females, it triggers ovulation and helps form the corpus luteum…
Correct answer: LH- A. Selection
- B. Acclimatization
- C. Hybridization
- D. Evolution
- E. Back crossing
Explanation: Hybridization is the process of crossing two different species or varieties to produce a hybrid organism that typically exhibits traits…
Correct answer: Hybridization- A. Skin cancer
- B. Lung cancer
- C. Blood cancer
- D. Lymph cancer
- E. Testicular cancer
Explanation: Testicular cancer primarily affects younger men, with the highest incidence occurring in those between the ages of 15 and 35.
Correct answer: Testicular cancer- A. Ovaries
- B. Oviduct
- C. Cervix
- D. Seminiferous tubules
Explanation: Seminiferous tubules are coiled structures located within the testes and are the site of sperm production (spermatogenesis) in males.
Correct answer: Seminiferous tubules- A. Oocyte
- B. Sperms
- C. Polar body
- D. Spermatogonia
Explanation: Sertoli cells secrete testicular fluid into the seminiferous tubules, providing a liquid medium that supports sperm development.
Correct answer: Sperms- A. Testosterone
- B. Follicle stimulating hormone
- C. Luteinizing hormone
- D. Progesterone
Explanation: Progesterone is a steroid hormone produced primarily by the corpus luteum in the ovaries after ovulation and, during pregnancy, by the…
Correct answer: Progesterone- A. Follicles reach maximum size
- B. Follicle degenerates
- C. Graafian follicle ovulates
- D. The follicle starts to mature
Explanation: The follicle that is not selected for ovulation begins to break down. The oocyte and surrounding granulosa cells undergo apoptosis…
Correct answer: Follicle degenerates- A. Transport sperms
- B. Connect with urethra
- C. Produce semen
- D. Hold the process of spermatogenesis
Explanation: During ejaculation, sperms are transported from the epididymis through the vas deferens and into the urethra for expulsion.
Correct answer: Transport sperms- A. Secondary spermatocyte
- B. Spermatids
- C. Primary spermatocytes
- D. Sperms
Explanation: Primary spermatocytes are diploid cells in the testes formed from spermatogonia.
Correct answer: Primary spermatocytes- A. Epididymis
- B. Interstitial cells
- C. Seminiferous tubules
- D. Sertoli cells
Explanation: Seminiferous tubules are tightly coiled structures located within the testes, and they are the site of spermatogenesis, the process of…
Correct answer: Seminiferous tubules- A. Oogonia
- B. Ovum
- C. Primary oocytes
- D. Secondary oocytes
Explanation: Primary oocytes are the initial cells in oogenesis that pause in prophase I until puberty.
Correct answer: Primary oocytes- A. After 6 days of start of menstruation
- B. After 10 days of start of menstruation
- C. After 14 days of start of menstruation
- D. After 27 days of start of menstruation
Explanation: Ovulation in a typical 28-day menstrual cycle occurs around day 14. It marks the release of a mature egg from the ovary, triggered by a…
Correct answer: After 14 days of start of menstruation- A. Gonorrhea
- B. Influenza
- C. Tuberculosis
- D. Cholera
Explanation: Gonorrhoea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. It can be spread through:1.
Correct answer: Gonorrhea- A. Androgen
- B. Prostaglandins
- C. Oxytocin
- D. Testosterone
Explanation: These lipid compounds, present in semen, help stimulate contractions in the female reproductive tract, particularly in the uterus and…
Correct answer: Prostaglandins- A. Cowper's gland
- B. Prostate gland
- C. Seminal vesicle
- D. Vas deferens
Explanation: The Cowper's glands, also known as bulbourethral glands, produce a clear, alkaline mucus-like fluid that helps neutralize the acidity of…
Correct answer: Cowper's gland- A. Graafian follicle
- B. Ovum
- C. Oogonium
- D. Oocyte
Explanation: The Graafian follicle plays a crucial role in ovulation, and its transformation into the corpus luteum is vital for hormonal regulation…
Correct answer: Graafian follicle- A. Endometrium
- B. Myometrium
- C. Mesometrium
- D. Perimetrium
Explanation: The perimetrium is the outermost layer of the uterus, also known as the serosa.
Correct answer: Perimetrium- A. Males
