Free Reproductive Anatomy and Conception MCQs with Answers

• A. The fundus
• B. The body
• C. The cervix
• D. The uterine tube

Explanation: The cervix is the lower, narrow part of the uterus that projects into the vagina.

• A. 23 chromosomes
• B. .length 46 chromosomes
• C. 44 chromosomes
• D. 92 chromosomes

Explanation: A normal sperm or ovum is haploid and contains 23 chromosomes. Fertilisation restores the diploid number of 46 chromosomes in the zygote…

• A. The fall in ovarian hormones causes endometrial shedding
• B. The rise in human chorionic gonadotropin causes uterine bleeding
• C. The sudden release of follicle-stimulating hormone destroys the endometrium
• D. The increase in oxytocin causes the functional layer to detach

Explanation: When the corpus luteum regresses, progesterone and estrogen levels fall, causing the functional endometrial layer to shed.

• A. Granulosa cells
• B. Theca interna cells
• C. Corpus albicans cells
• D. Germinal epithelial cells

Explanation: Theca interna cells respond to luteinizing hormone and produce androgen precursors.

• A. Prophase I of meiosis
• B. Metaphase I of meiosis
• C. Prophase II of meiosis
• D. Metaphase II of meiosis

Explanation: Primary oocytes begin meiosis before birth and remain arrested in prophase I until selected for maturation.

• A. The acrosome reaction
• B. The menstrual reaction
• C. The luteal reaction
• D. The endometrial reaction

Explanation: The acrosome reaction releases enzymes from the sperm head that help it penetrate the zona pellucida.

• A. Human chorionic gonadotropin
• B. Follicle-stimulating hormone
• C. Prolactin
• D. Oxytocin

Explanation: The early trophoblast produces human chorionic gonadotropin, which supports the corpus luteum and its progesterone secretion.

• A. The iliac crest
• B. The ischial spines
• C. The pubic symphysis
• D. The sacral promontory

Explanation: The ischial spines project inward and form an important landmark for assessing the midpelvis and fetal station.

• A. The trophoblast and maternal endometrium
• B. The corpus luteum and cervical mucus
• C. The zona pellucida and ovarian stroma
• D. The myometrium and uterine peritoneum

Explanation: The fetal part of the placenta develops mainly from the trophoblast, while the maternal part develops from the modified endometrium.

• A. Arrange urgent assessment for possible ruptured ectopic pregnancy
• B. Advise bed rest and repeat a pregnancy test next week
• C. Offer oral fluids and document the pain for routine review
• D. Teach her that mild discomfort is normal in early pregnancy

Explanation: The symptoms suggest internal bleeding from a possible ruptured ectopic pregnancy, so urgent assessment is required.

• A. Endometrium
• B. Myometrium
• C. Perimetrium
• D. Parametrium

Explanation: The myometrium is the thick smooth-muscle layer of the uterus and produces contractions during labour.

• A. Seminal vesicle
• B. Prostate gland
• C. Bulbourethral gland
• D. Epididymis

Explanation: The prostate surrounds the proximal urethra and contributes a thin, slightly alkaline fluid to semen.

• A. Leydig cells
• B. Sertoli cells
• C. Prostatic cells
• D. Bulbourethral cells

Explanation: Sertoli cells support, nourish and regulate developing sperm within the seminiferous tubules.

• A. A sustained slight rise in temperature
• B. A sustained fall in temperature
• C. A sudden rise before menstruation only
• D. No temperature change throughout the cycle

Explanation: Progesterone released after ovulation raises basal body temperature slightly, and the rise remains during the luteal phase.

• A. Mitosis
• B. Meiosis
• C. Binary fission
• D. Budding

Explanation: Meiosis reduces the chromosome number by half and produces genetically varied gametes.

• A. The chromosome carried by the ovum
• B. The chromosome carried by the sperm
• C. The number of polar bodies formed
• D. The thickness of the zona pellucida

Explanation: The ovum normally contributes an X chromosome, whereas the sperm contributes either an X or a Y chromosome.

• A. Sperm may remain viable in the female tract for several days
• B. The ovum remains viable for about one menstrual cycle
• C. Implantation occurs immediately after intercourse
• D. Menstruation permanently stores sperm in the uterus

Explanation: Sperm can remain viable in favourable cervical mucus for several days, so they may be present when ovulation occurs.

• A. Trophoblast
• B. Inner cell mass
• C. Zona pellucida
• D. Chorionic cavity

Explanation: The inner cell mass, also called the embryoblast, develops into the embryo proper.

• A. Decidua
• B. Amnion
• C. Chorion
• D. Allantois

Explanation: The endometrium undergoes pregnancy-related changes and is called the decidua after implantation.

• A. Labia majora
• B. Cervix
• C. Uterine tube
• D. Endometrium

Explanation: The labia majora are folds of skin forming part of the vulva and help protect the external genital openings.
