The interstitial (Leydig) cells located between the seminiferous tubules secrete:
FSH
Oestrogen
Testosterone
LH
Sperm maturation and storage primarily occur in the:
Seminiferous tubules
Deferent duct
Epididymis
Prostate gland
The tail (flagellum) of a mature sperm provides for:
DNA storage
Energy
Motility
Ovum penetration
The optimal temperature for sperm production is approximately:
Equal to body temperature
∼ 3°C above body temperature
∼ 3°C below body temperature
At 0°C
Which structure suspends the testes and passes through the inguinal canal?
Deferent duct
Scrotal septum
Spermatic cord
Cremaster muscle
The muscular tube that transports sperm from the epididymis during ejaculation is the:
Urethra
Ejaculatory duct
Deferent duct (vas deferens)
Ureter
The structure formed by the union of the vas deferens and the seminal vesicle duct is the:
Prostatic urethra
Seminal vesicle
Epididymis
Ejaculatory duct
The seminal vesicles contribute approximately what percentage of the semen volume?
∼ 10%
∼ 30%
∼ 60%
∼ 90%
The seminal fluid is viscous and alkaline to:
Provide energy
Cause clotting
Protect sperm from vaginal acidity
Aid sperm production
The prostate gland is located below the bladder and surrounds the:
Vas deferens
Seminal vesicle
Rectum
Urethra
The prostate gland contributes approximately what percentage of the semen volume?
∼ 60%
∼ 30%
∼ 10%
∼ 5%
The thin, milky prostatic fluid is responsible for semen's white color and contains an enzyme that:
Metabolizes fructose
Causes clotting to thicken semen in the vagina
Neutralizes semen pH
Increases sperm motility
The shortest and narrowest part of the male urethra, passing through the perineal membrane, is the:
Prostatic urethra
Membranous urethra
Penile (spongy) urethra
External urethral orifice
The involuntary smooth muscle sphincter located at the bladder neck is the:
External urethral sphincter
Internal urethral sphincter
Cremaster muscle
Dartos muscle
The voluntary skeletal muscle sphincter surrounding the membranous urethra is the:
Internal urethral sphincter
Cremaster muscle
External urethral sphincter
Corpus spongiosum
The erectile tissue that surrounds the urethra in the penis is the:
Corpora cavernosa
Corpus spongiosum
Root
Glans penis
The process of ejaculation involves powerful rhythmic contractions of the smooth muscle in the:
Prostate gland
Seminal vesicle
Vas deferens (Deferent duct)
Bladder
The length of a human gestation period is approximately:
∼ 28 days
∼ 28 weeks
∼ 40 weeks
∼ 52 weeks
During pregnancy, the implanted blastocyst secretes hCG primarily to:
Stimulate milk production
Maintain the corpus luteum
Trigger parturition
Stimulate new follicle growth
The transition phase where the reproductive cycle becomes irregular and eventually stops is:
Puberty
Menarche
Ovulation
Menopause
Menopause is primarily caused by the depletion of viable:
FSH
Oocytes (follicles)
LH
Progesterone
Chlamydia is a bacterial STI that, in females, commonly causes cervicitis and can spread upward to cause:
Syphilis
Pelvic inflammatory disease (PID)
Urethritis
Endometrial carcinoma
In males, Gonorrhoea primarily causes suppurative:

Prostatitis
Urethritis
Chancres
The characteristic lesion of the primary stage of Syphilis is a:
Mucosal ulceration
Chancre (painless ulcer)
Rash
Gumma
The sexually transmitted infection caused by a protozoan parasite (not a bacterium or virus) is:
Chlamydia
Gonorrhoea
Trichomonas vaginalis
Genital herpes
Overgrowth of the commensal Candida albicans causing vulvovaginal candidiasis is often triggered by antibiotic use because it kills:
E. coli
Sperm
Lactobacillus (beneficial bacteria)
Viruses
The most common cause of cervical carcinoma ( >90% of cases) is infection by:
Gonorrhoea
Chlamydia
HPV (Human Papillomavirus)
Herpes Simplex Virus
Endometriosis involves the ectopic growth of endometrial tissue outside the uterus, commonly at which site?
Stomach, liver, pancreas
Ovaries, uterine tubes, pelvic peritoneum
Urethra, bladder
Clitoris, labia majora
The most common, benign tumors of the myometrium that grow during reproductive years but regress after menopause are:
Endometrial carcinoma

Leiomyoma (fibroids)
Chocolate cysts
The disorder where endometrial tissue grows into the muscular wall of the uterus (myometrium) is:
Endometriosis
Leiomyoma
Adenomyosis
Endometrial hyperplasia
