NLE Reproductive Health & Family Planning Reviewer 2026

Answer: B. Seminiferous tubules of the testes

Step 1 – Identify the question: It asks where sperm are actually produced. Step 2 – Recall anatomy: The testes contain two functional cell types in the seminiferous tubules — Sertoli cells (which support developing sperm) and the surrounding Leydig cells (which produce testosterone). Sperm production (spermatogenesis) takes place inside the seminiferous tubules. Step 3 – Eliminate wrong options: The epididymis is where sperm mature and gain motility after they are made — not where they are produced. The vas deferens is only a transport tube. The seminal vesicles secrete fructose-rich fluid that nourishes sperm but do not produce sperm. Step 4 – Confirm the answer: Seminiferous tubules of the testes is correct. This is a high-yield NLE fact for NCM 107.

Answer: C. Vas (ductus) deferens

Step 1 – Understand the procedure: A vasectomy is a male sterilisation method that prevents sperm from reaching the ejaculate. Step 2 – Trace the sperm pathway: Testes → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Penis. To block sperm transport, the vas deferens is the accessible, surgically convenient structure that is cut (severed) and ligated (tied). Step 3 – Eliminate wrong options: The epididymis is where sperm mature — cutting it would be more complex and is not the procedure. The urethra is the shared passage for urine and semen; severing it would cause urinary problems, which is not the goal. The ejaculatory duct is located deep inside the prostate, making it inaccessible for a simple surgical approach. Step 4 – Key teaching point: After vasectomy, the man still ejaculates fluid from the seminal vesicles and prostate, but no sperm are present. This is an important patient-teaching point in family planning.

Answer: D. Human chorionic gonadotropin (hCG)

Step 1 – Understand how pregnancy tests work: A pregnancy test detects a hormone that appears in the urine or blood only after a fertilised egg has implanted and begun to develop. Step 2 – Identify that hormone: After implantation (6–10 days after fertilisation), the trophoblast (early placental tissue) secretes hCG. hCG maintains the corpus luteum so progesterone production continues, preventing menstruation and supporting the pregnancy. Step 3 – Eliminate wrong options: Progesterone is elevated in pregnancy but is not the marker detected by standard tests. Oestrogen also rises in pregnancy but is not the test marker. LH surges at mid-cycle to trigger ovulation — some ovulation predictor kits detect LH, but these are different from pregnancy tests. Step 4 – NLE pearl: hCG is called the 'hormone of pregnancy confirmation.' Its rise is the basis of both urine and serum pregnancy tests. Levels peak around 8–10 weeks of gestation.

Answer: B. The first day of menstrual bleeding

Step 1 – Understand cycle counting: In reproductive health, all cycle calculations (predicting ovulation, calculating expected next period, etc.) start from a clear, identifiable event. Step 2 – Define Day 1: By universal convention, Day 1 of the menstrual cycle is the FIRST DAY of menstrual bleeding (the start of menstruation). This is consistent across all clinical references and is used in patient teaching for fertility awareness methods. Step 3 – Eliminate wrong options: Ovulation occurs around Day 14 of a 28-day cycle, not Day 1. The last day of bleeding varies (Day 2–7) and is not used as the reference point. Progesterone peaks during the luteal phase (approximately Days 20–22), which is mid-to-late cycle. Step 4 – Clinical application: Teaching patients to correctly identify Day 1 is fundamental to cycle tracking, fertility awareness, and calculating the fertile window.

Answer: B. Luteinising hormone (LH)

Step 1 – Follow the hormonal sequence leading to ovulation: During the follicular phase, a dominant (Graafian) follicle grows and produces rising amounts of oestrogen. Step 2 – Positive feedback: High oestrogen levels (from the dominant follicle) send a positive feedback signal to the anterior pituitary, triggering a sharp, dramatic surge of LH. Step 3 – LH surge causes ovulation: The LH surge causes the mature follicle to rupture and release the ovum approximately 36–40 hours after the surge begins. This is why ovulation predictor kits measure urine LH — the surge predicts imminent ovulation. Step 4 – Eliminate wrong options: FSH stimulates follicle growth but is not the trigger for rupture. Progesterone is produced AFTER ovulation by the corpus luteum — it cannot cause ovulation. Oestrogen rises before ovulation and stimulates the LH surge (positive feedback), but oestrogen itself does not directly rupture the follicle. Step 5 – NLE pearl: 'LH surge = ovulation trigger' is one of the most commonly tested facts in NCM 107 board questions.

Answer: C. In the ampulla (outer third) of the fallopian tube

Step 1 – Trace the ovum's journey: After ovulation, the fimbriae sweep the released ovum into the fallopian (uterine) tube. Step 2 – Identify the site of fertilisation: Sperm travel up through the cervix, uterus, and into the fallopian tube. Fertilisation normally occurs in the ampulla, which is the widest, outer third of the fallopian tube. This is where sperm and ovum most commonly meet. Step 3 – What happens after fertilisation: The fertilised egg (zygote) begins dividing as it is transported by cilia and peristalsis toward the uterus, arriving approximately 3–4 days later and implanting 6–10 days after fertilisation. Step 4 – Eliminate wrong options: The uterine body is where implantation occurs, not fertilisation. The fimbriae sweep the ovum into the tube but are not the fertilisation site. The cervix is too far from where the sperm and ovum meet. Step 5 – Clinical relevance: If the zygote implants in the fallopian tube instead of the uterus, an ectopic (tubal) pregnancy results — a life-threatening emergency.

Answer: C. Progesterone

Step 1 – Understand BBT charting: Women using the Basal Body Temperature (BBT) method track their resting temperature each morning to identify ovulation. Step 2 – The hormonal cause: After ovulation, the ruptured follicle becomes the corpus luteum. The corpus luteum secretes large amounts of progesterone. Progesterone has a thermogenic (heat-raising) effect on the hypothalamus, causing a sustained rise of approximately 0.3–0.5°C in BBT. Step 3 – Clinical significance: The BBT remains elevated throughout the luteal phase. If the temperature stays elevated beyond the expected period, it suggests pregnancy (because hCG maintains the corpus luteum and its progesterone output). Step 4 – Eliminate wrong options: Oestrogen is the dominant pre-ovulatory hormone and is associated with the thin, stretchy cervical mucus (spinnbarkeit) — it does NOT raise BBT. FSH stimulates follicle growth in the early cycle. hCG appears only after implantation and does not directly raise BBT — it maintains progesterone, which does. Step 5 – Memory tip: Progesterone = Pro-pregnancy hormone → raises temperature to create a warm environment for implantation.

Answer: D. Menorrhagia

Step 1 – Break down the terminology: Understanding prefixes and suffixes helps decode menstrual disorder terms. Step 2 – Define menorrhagia: 'Meno' refers to the menstrual period; 'rrhagia' means excessive flow or haemorrhage. Menorrhagia = heavy or prolonged menstrual bleeding that occurs at regular intervals. Normal blood loss is 30–80 mL; menorrhagia involves >80 mL or periods lasting >7 days. Step 3 – Eliminate wrong options: • Metrorrhagia = bleeding BETWEEN periods ('metro' = uterus, referring to irregular/inter-menstrual bleeding). • Amenorrhoea = ABSENCE of menstruation ('a' = without, 'meno' = menses). • Dysmenorrhoea = PAINFUL menstruation ('dys' = difficult/painful) — not heavy flow. Step 4 – Clinical nursing action: Menorrhagia warrants assessment for anaemia (check CBC), hormonal causes, fibroids, or coagulation disorders. Nursing diagnosis: Risk for deficient fluid volume / Activity intolerance related to heavy blood loss.

Answer: C. Endometrium

Step 1 – Know the three layers of the uterus: The uterine wall has three distinct layers, each with a unique function. Step 2 – Define each layer: • Perimetrium – the outermost serous (peritoneal) layer; acts as a protective covering. • Myometrium – the thick middle muscular layer; contracts powerfully during labour to expel the baby, and clamps blood vessels after delivery to prevent postpartum haemorrhage. • Endometrium – the innermost mucosal lining; undergoes cyclical changes with each menstrual cycle. Step 3 – The endometrium's dual role: Under oestrogen (proliferative phase), the endometrium thickens and regenerates. Under progesterone (secretory phase), it becomes glandular and nutrient-rich — ready for implantation. If no fertilisation occurs, the drop in hormones causes the functional layer of the endometrium to shed = menstruation. Step 4 – NLE pearl: Questions about menstruation and implantation both point to the endometrium. The cervix is the lower opening of the uterus, not a layer.

Answer: C. The father, because the sperm carries either an X or Y chromosome

Step 1 – Recall chromosome basics: Humans have 46 chromosomes (23 pairs). The 23rd pair are the sex chromosomes. Step 2 – Understand sex determination: • All ova (eggs) produced by the mother carry an X chromosome (females are XX, so every egg gets one X). • Sperm produced by the father carry EITHER an X chromosome OR a Y chromosome (males are XY, so half the sperm carry X and half carry Y). Step 3 – At fertilisation: • If an X-carrying sperm fertilises the ovum → XX → female baby. • If a Y-carrying sperm fertilises the ovum → XY → male baby. Step 4 – Conclusion: Because the mother always contributes an X, and the father contributes either X or Y, the SEX-DETERMINING CHROMOSOME comes from the father's sperm. Step 5 – Clinical relevance in patient teaching: This is an important concept to address cultural myths and misconceptions, particularly in communities where mothers are blamed for the sex of the child.

Answer: D. Days 8 to 19 (shortest 26 − 18 = 8; longest 30 − 11 = 19)

Step 1 – Recall the formula: Fertile window = (Shortest cycle − 18) to (Longest cycle − 11). Step 2 – Apply: 26 − 18 = Day 8 (first fertile day); 30 − 11 = Day 19 (last fertile day). Step 3 – The fertile window is Days 8–19. Step 4 – The client should abstain from intercourse or use a backup method during this window. Step 5 – Note: This formula is only applied after tracking at least 6 cycles; irregular cycles make this method unreliable.

Answer: B. ACHES

Step 1 – ACHES stands for: Abdominal pain (severe), Chest pain or shortness of breath, Headache (severe), Eye problems (visual changes), Severe leg pain (calf). Step 2 – These signs suggest serious complications such as thromboembolism (blood clots), pulmonary embolism, or stroke — all possible but rare risks of estrogen-containing pills. Step 3 – PAINS is the mnemonic for IUD danger signs, not COCs. Step 4 – GATHER is the counseling framework (Greet, Ask, Tell, Help, Explain, Return). Step 5 – PLISSIT is a sexuality counseling model. Teaching ACHES empowers the client to seek care promptly if these signs appear.
