Free Reproductive Anatomy and Conception MCQs with Answers
50 Reproductive Anatomy and Conception MCQs from Midwifery and Obstetric Nursing, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Female and male reproductive organs, pelvic anatomy, gametogenesis, the menstrual cycle and the hormonal control of ovulation lead into fertilisation, implantation and early embryonic development. Questions distinguish ovulation from menstruation, fertilisation from implantation, and the normal anatomical changes that allow conception and pregnancy to occur.

41. Which structure divides the bony pelvis into the greater pelvis above and the lesser pelvis below?
- A. Pelvic brim
- B. Obturator foramen
- C. Ischial spine
- D. Sacral promontory
Explanation: The pelvic brim, also called the pelvic inlet, separates the greater pelvis from the lesser pelvis.
Correct answer: Pelvic brim42. Which male reproductive gland releases a clear mucus before ejaculation that lubricates the urethra?
- A. Prostate gland
- B. Seminal vesicle
- C. Bulbourethral gland
- D. Epididymal gland
Explanation: The bulbourethral glands produce a mucus-like secretion that lubricates the urethra and helps neutralise residual acidity.
Correct answer: Bulbourethral gland- A. Progesterone
- B. Oestrogen
- C. Human chorionic gonadotropin
- D. Oxytocin
Explanation: Oestrogen from developing ovarian follicles promotes the proliferative growth of the endometrium during the pre-ovulatory phase.
Correct answer: Oestrogen- A. Acrosome reaction
- B. Cortical reaction
- C. Capacitation reaction
- D. Decidual reaction
Explanation: The cortical reaction changes the zona pellucida after sperm-oocyte fusion and blocks polyspermy.
Correct answer: Cortical reaction- A. Two secondary spermatocytes
- B. Four spermatids
- C. One primary spermatocyte
- D. Two mature spermatozoa
Explanation: Meiosis I divides one primary spermatocyte into two haploid secondary spermatocytes.
Correct answer: Two secondary spermatocytes46. A woman asks why the fertilised ovum has a diploid chromosome number. Which explanation is correct?
- A. The ovum duplicates its chromosomes before ovulation
- B. The sperm and oocyte nuclei fuse during fertilisation
- C. The uterus adds chromosomes during implantation
- D. The corpus luteum supplies chromosomes to the zygote
Explanation: Fertilisation combines the haploid chromosomes of the sperm and secondary oocyte, restoring the diploid chromosome number in the zygote.
Correct answer: The sperm and oocyte nuclei fuse during fertilisation- A. Corpus luteum
- B. Primary follicle
- C. Ovarian medulla
- D. Germinal epithelium
Explanation: The ruptured mature follicle becomes the corpus luteum, which secretes mainly progesterone after ovulation.
Correct answer: Corpus luteum- A. The functional layer is shed
- B. The basal layer is completely destroyed
- C. The myometrium changes into decidua
- D. The cervix becomes the placenta
Explanation: Menstrual bleeding results from shedding of the functional layer of the endometrium when ovarian hormone levels fall.
Correct answer: The functional layer is shed- A. Cleavage
- B. Gastrulation
- C. Ovulation
- D. Implantation
Explanation: Gastrulation reorganises the early embryo to form ectoderm, mesoderm and endoderm.
Correct answer: Gastrulation- A. Granulosa cell
- B. Leydig cell
- C. Sertoli cell
- D. Trophoblast cell
Explanation: Granulosa cells surround the oocyte within the ovarian follicle and provide support while responding to follicle-stimulating hormone.
Correct answer: Granulosa cell
