Free Reproductive System MCQs with Answers
40 Reproductive System MCQs from Anatomy and Physiology for Nursing, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
The reproductive system covers the male and female reproductive organs, gamete formation, the menstrual and ovarian cycles, fertilization, implantation and pregnancy. It explains the roles of FSH, LH, oestrogen, progesterone and testosterone, while distinguishing spermatogenesis from oogenesis and the reproductive organs from the accessory glands.

- A. The day menstrual bleeding begins
- B. The day ovulation is detected
- C. The day cervical mucus becomes thin
- D. The day progesterone reaches its peak
Explanation: The first day of menstrual bleeding is day one of the menstrual cycle. Ovulation and the progesterone peak occur later, during the middle…
Correct answer: The day menstrual bleeding begins- A. Before it leaves the ovary
- B. During follicle development
- C. Only after fertilization occurs
- D. At the start of menstruation
Explanation: The secondary oocyte remains arrested in meiosis II and completes it only when a sperm penetrates the oocyte.
Correct answer: Only after fertilization occurs- A. Formation of a haploid ovum
- B. Formation of a diploid zygote
- C. Release of a mature follicle
- D. Formation of the corpus luteum
Explanation: Fertilization combines the haploid male and female nuclei to form a diploid zygote.
Correct answer: Formation of a diploid zygote- A. Human chorionic gonadotropin
- B. Follicle-stimulating hormone
- C. Oxytocin
- D. Prolactin
Explanation: Human chorionic gonadotropin, produced by the developing chorionic tissue, maintains the corpus luteum early in pregnancy.
Correct answer: Human chorionic gonadotropin- A. It becomes thick and forms a firm plug
- B. It becomes thin, clear and more stretchable
- C. It becomes dry and blocks sperm movement
- D. It becomes heavily blood-stained and clotted
Explanation: Rising oestrogen makes cervical mucus thinner, clearer and more stretchable, allowing sperm to pass more easily.
Correct answer: It becomes thin, clear and more stretchable- A. It produces sperm for the developing fetus
- B. It exchanges oxygen, nutrients and wastes
- C. It stores mature ova for later fertilization
- D. It directly opens the cervix during labour
Explanation: The placenta provides exchange of oxygen, nutrients and waste products between maternal and fetal blood without normally mixing them…
Correct answer: It exchanges oxygen, nutrients and wastes- A. Mild nausea after waking
- B. Breast tenderness during the day
- C. Severe pain with dizziness and bleeding
- D. Increased urinary frequency at night
Explanation: Severe unilateral pain with dizziness and bleeding may indicate a ruptured ectopic pregnancy and internal haemorrhage.
Correct answer: Severe pain with dizziness and bleeding- A. It contains 46 chromosomes before fertilization
- B. It contains 23 chromosomes before fertilization
- C. It contains 23 pairs after meiosis is complete
- D. It contains no chromosomes until fertilization
Explanation: Sperm and ova are haploid gametes, each normally containing 23 chromosomes.
Correct answer: It contains 23 chromosomes before fertilization- A. Fundus
- B. Myometrium
- C. Cervix
- D. Uterine tube
Explanation: The cervix is the lower narrow part of the uterus and communicates with the vagina through the cervical canal.
Correct answer: Cervix- A. They support and nourish developing sperm cells
- B. They produce testosterone for male development
- C. They store mature sperm cells for ejaculation
- D. They secrete fructose-rich fluid into semen
Explanation: Sertoli cells support developing sperm cells and help regulate spermatogenesis.
Correct answer: They support and nourish developing sperm cells- A. Maintaining the testes slightly below body temperature
- B. Producing hormones that stimulate sperm release
- C. Providing alkaline fluid for sperm movement
- D. Moving sperm from the testes into the urethra
Explanation: The scrotum helps keep the testes cooler than the abdominal cavity, which supports normal spermatogenesis.
Correct answer: Maintaining the testes slightly below body temperature- A. A thin, slightly alkaline fluid
- B. A thick fluid rich in ovarian hormones
- C. A mucus layer that nourishes the ovum
- D. A concentrated fluid containing mature sperm
Explanation: The prostate contributes a thin, slightly alkaline secretion that supports sperm activity and helps neutralize acidity.
Correct answer: A thin, slightly alkaline fluid- A. Human chorionic gonadotropin
- B. Follicle-stimulating hormone
- C. Luteinizing hormone
- D. Human placental lactogen
Explanation: Human chorionic gonadotropin, or hCG, is produced by trophoblastic tissue soon after implantation and is detected in urine and blood…
Correct answer: Human chorionic gonadotropin- A. It reduces secretion of follicle-stimulating hormone
- B. It increases secretion of luteinizing hormone
- C. It stimulates testosterone release from Leydig cells
- D. It causes contraction of the seminiferous tubules
Explanation: Inhibin provides negative feedback mainly by reducing FSH secretion, helping regulate sperm production.
Correct answer: It reduces secretion of follicle-stimulating hormone- A. Avoid digital vaginal examination and notify the provider
- B. Perform a digital examination to assess cervical dilation
- C. Encourage walking to assess whether bleeding decreases
- D. Apply firm fundal pressure to reduce the bleeding
Explanation: Painless bright-red bleeding in late pregnancy may indicate placenta previa, so a digital vaginal examination can provoke severe…
Correct answer: Avoid digital vaginal examination and notify the provider- A. Massage the fundus and assess the response
- B. Place the woman flat and restrict oral fluids
- C. Apply an abdominal binder over the uterus
- D. Encourage the woman to walk to the bathroom
Explanation: A boggy uterus commonly indicates uterine atony, a major cause of postpartum haemorrhage.
Correct answer: Massage the fundus and assess the response- A. Avoid prolonged testicular heat because it can impair sperm production
- B. Use tight clothing to keep the testes close to the body
- C. Take extra testosterone to increase the number of sperm cells
- D. Reduce water intake to prevent dilution of seminal fluid
Explanation: Excessive heat can interfere with spermatogenesis because sperm production requires a temperature slightly below core body temperature.
Correct answer: Avoid prolonged testicular heat because it can impair sperm production- A. It allows exchange of oxygen and nutrients across a barrier
- B. It normally allows maternal and fetal blood to mix freely
- C. It produces all fetal blood cells throughout pregnancy
- D. It carries urine from the fetal bladder to the mother's kidneys
Explanation: The placenta permits exchange of oxygen, nutrients, and wastes between maternal and fetal circulations across placental tissue.
Correct answer: It allows exchange of oxygen and nutrients across a barrier- A. The findings are consistent with menopause
- B. The findings indicate the middle of the fertile cycle
- C. The findings indicate excessive corpus luteum activity
- D. The findings indicate a normal early pregnancy
Explanation: Menopause is associated with ovarian failure, reduced oestrogen production, and loss of negative feedback, which causes FSH to rise.
Correct answer: The findings are consistent with menopause- A. Vas deferens
- B. Seminiferous tubule
- C. Seminal vesicle
- D. Bulbourethral gland
Explanation: The vas deferens is a muscular duct that carries mature sperm from the epididymis toward the ejaculatory duct during ejaculation.
Correct answer: Vas deferens
