- A. Inhibition of ICHS
- B. Sperm production
- C. Inhibition of FSH
- D. Limit spermatogenesis
Explanation: Testosterone's primary functions include promoting sperm production and regulating hormones such as FSH.
Correct answer: Limit spermatogenesis- A. Progesterone production
- B. Estrogen production
- C. Ovulation
- D. HCG production
Explanation: Ovaries do not directly produce HCG (Human Chorionic Gonadotropin). HCG is produced by the placenta during pregnancy.
Correct answer: HCG production- A. Progesterone
- B. FSH
- C. LH
- D. Testosterone
Explanation: The Corpus Luteum is responsible for producing and secreting progesterone, which helps prepare the uterine lining for potential…
Correct answer: Progesterone- A. Acts on kidney tubules
- B. Stimulates ICSH
- C. Perform cellular functions
- D. Dilate milk ducts of mammary glands
Explanation: Dilate milk ducts of mammary glands: Correct, as oxytocin is responsible for stimulating milk ejection by contracting the muscles around…
Correct answer: Dilate milk ducts of mammary glands- A. Start of menstruation
- B. Start of ovulation
- C. Stop of ova production
- D. Degeneration of ovaries
Explanation: Menopause is the stage in a woman's life when her ovaries stop producing eggs (ova) and she ceases to have menstrual periods, typically…
Correct answer: Stop of ova production- A. Ovary
- B. Uterus
- C. Stimulated follicles
- D. Hypothalamus
Explanation: The production of Follicle-stimulating hormone (FSH) and Luteinizing Hormone (LH) from the pituitary gland in females is controlled by…
Correct answer: Hypothalamus- A. Uterus
- B. Kidney
- C. Fallopian tube
- D. Stomach
Explanation: In human females, the small, pear-shaped, muscular, distensible, sac-like organ where gestation takes place is UterusThe uterus is where…
Correct answer: Uterus- A. Endometrium
- B. Myometrium
- C. Perimetrium
- D. Ovaries
Explanation: The labor pains to expel the fetus are due to the action of oxytocin on Myometrium Oxytocin is a hormone that is released by the pituitary…
Correct answer: Myometrium- A. Oviduct
- B. Ovaries
- C. Uterus
- D. Cervix
Explanation: Option A is correct.Fallopian tube is also known as oviduct.Fallopian tubes are muscular tubes that connect the ovaries to the uterus.
Correct answer: Oviduct- A. Bacterial
- B. Fungal
- C. Protozoic
- D. Viral
Explanation: Option A is correct.Syphilis is a bacterial disease. It is caused by the bacterium Treponema pallidum.
Correct answer: Bacterial- A. Skin rash on neck

- C. Painful urination
- D. Chancre
Explanation: Option C is correct.The most common symptom of gonorrhea in males is painful urination.
Correct answer: Painful urination- A. Leydig
- B. Inhibin
- C. Sertoli
- D. TSH
Explanation: Option C is correct.FSH (Follicle stimulating hormones) stimulates spermatogenesis by stimulating Sertoli cells to complete the…
Correct answer: Sertoli- A. Vas deferens
- B. Epididymis
- C. Scrotum
- D. Vasa efferentia
Explanation: Option C is correct.The testes are male gonads which are situated outside the abdomen within a skin pouch called scrotum.
Correct answer: Scrotum- A. Viviparous
- B. Oviparous
- C. Ovoviviparous
- D. None of the above
Explanation: This is the correct answer. Humans are viviparous animals, which means they give birth to live young.
Correct answer: Viviparous- A. Protect sperms
- B. Provides liquid medium to sperms
- C. Provides nourishment to sperms
- D. Secrete testosterone
Explanation: Sertoli cells do not secrete testosterone. Instead, they play a crucial role in supporting and nurturing developing sperm cells
Correct answer: Secrete testosterone- A. Follicle stimulating harmone
- B. Gonadotrophins
- C. Ovarian hormones
- D. None of these
Explanation: At the beginning of the menstrual phase, the levels of ovarian hormones, specifically estrogen and progesterone, are at their lowest.
Correct answer: Ovarian hormones- A. Wastages
- B. Gases
- C. Blood
- D. Nutrients
Explanation: Correct, because maternal and fetal blood do not mix; only nutrients and gases diffuse through the placenta.
Correct answer: Blood- A. Graafian follicle
- B. Corpus allatum
- C. Primary follicle
- D. Corpus luteum
Explanation: Correct. After ovulation, the ruptured follicle forms the corpus luteum, which secretes progesterone to maintain the uterine lining for…
Correct answer: Corpus luteum- A. Vas deferens
- B. Ejaculatory duct
- C. Urinogenital duct
