Explanation: Spermatogonia are the male germ cells that undergo meiosis to produce sperms.
Q4: Which hormone is secreted by Leydig cells?
(a) Testosterone
(b) Estrogen
(c) Progesterone
(d) Oxytocin
Explanation: Leydig cells produce androgens, mainly testosterone, essential for male reproduction.
Q5: What is the function of Sertoli cells?
(a) Hormone production
(b) Nutrition to germ cells
(c) Sperm storage
(d) Motility of sperms
Explanation: Sertoli cells provide nourishment to developing sperm cells within the seminiferous tubules.
Q6: Which part of the male reproductive system stores and transports sperms?
(a) Seminiferous tubules
(b) Accessory ducts
(c) Penis
(d) Bulbourethral glands
Explanation: Accessory ducts (rete testis, vasa efferentia, epididymis, vas deferens) store and transport sperms.
Q7: What is the name of the enlarged end of the penis?
(a) Shaft
(b) Glans penis
(c) Corpus cavernosa

Explanation: The glans penis is the sensitive, enlarged terminal part of the penis.
Q8: Which of the following is NOT a male accessory gland?
(a) Prostate gland
(b) Bulbourethral gland
(c) Seminal vesicles
(d) Mammary glands
Explanation: Mammary glands are part of the female reproductive system, not the male.
Q9: The secretion of which gland lubricates the penis?
(a) Prostate gland
(b) Bulbourethral gland
(c) Seminal vesicle
(d) Testes
Explanation: The bulbourethral glands secrete a fluid that lubricates the penis.
Q10: The primary female sex organs are:
(a) Ovaries
(b) Uterus
(c) Fallopian tubes
(d) Mammary glands
Explanation: The ovaries produce ova and hormones like estrogen and progesterone.
Q11: What is the approximate length of the fallopian tube?
(a) 5–7 cm
(b) 10–12 cm
(c) 15–20 cm
(d) 20–25 cm
Explanation: Each fallopian tube is about 10–12 cm long, facilitating the movement of ova.
Q12: The uterus is supported by:
(a) Pelvic wall ligaments
(b) Cervical muscles
(c) Endometrium
(d) Ovarian ligaments
Explanation: The uterus is attached to the pelvic wall through supporting ligaments.
Q13: What is the function of fimbriae in the female reproductive system?
(a) Release of ovum
(b) Capture of ovum
(c) Transportation of sperms
(d) Protection of uterus
Explanation: Fimbriae are finger-like projections that help capture the ovum during ovulation.
Q14: The endometrium is the:
(a) Middle layer of the uterus
(b) Innermost layer of the uterus
(c) Outer layer of the uterus
(d) Layer of fallopian tubes
Explanation: The endometrium lines the uterine cavity and undergoes cyclical changes during the menstrual cycle.
Q15: The process of formation of sperm is called:
(a) Spermiogenesis
(b) Spermatogenesis
(c) Oogenesis
(d) Fertilization
Explanation: Spermatogenesis is the process of sperm formation in males.
Q16: At what stage does oogenesis start in females?
(a) Puberty
(b) Fetal development
(c) Menopause
(d) Birth
Explanation: Oogenesis begins during fetal development, producing primary oocytes.
Q17: Which hormone induces ovulation?
(a) LH
(b) FSH
(c) Estrogen
(d) Progesterone
Explanation: The luteinizing hormone (LH) surge triggers ovulation.
Q18: How many chromosomes does a human spermatid contain?
(a) 23
(b) 46
(c) 92
(d) 12
Explanation: A human spermatid is haploid, containing 23 chromosomes.
Q19: The zona pellucida is:
(a) Part of the sperm head
(b) The outer covering of the ovum
(c) The middle layer of the uterus
(d) The hormone released by corpus luteum
Explanation: The zona pellucida is a glycoprotein layer surrounding the ovum.
Q20: What marks the beginning of the menstrual cycle?
(a) Menopause
(b) Menarche
(c) Ovulation
(d) Fertilization
Explanation: Menarche is the first menstrual period, marking the onset of puberty in females.
