Which of the following is not a natural/traditional contraceptive method?
- Coitus interruptus
- Periodic abstinence
- Lactational amenorrhea
- Vaults
- Q5NEET 2023 Manipur
Given below are two statements regarding oogenesis:
Statement I :- The primary follicles get surrounded by more layers of granulosa cells, a theca and shows fluid filled cavity antrum. Now it is called secondary follicle.
Statement II :- Graffian follicle ruptures to release the secondary oocyte from the ovary by the process called ovulation.
In the light of the above statements, choose the correct answer from the options given below:
- Statement I is correct but Statement II is false.
- Statement I is incorrect but Statement II is true
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false.

Key Sub-Topics & What's Tested
Male Reproductive System
Testis structure, seminiferous tubules, spermatogenesis, accessory glands (seminal vesicle, prostate, bulbourethral), epididymis, vas deferens.
Female Reproductive System
Ovary structure, ovarian follicles, Graafian follicle, oviducts, uterus layers (perimetrium, myometrium, endometrium), vulva, mammary glands.
Gametogenesis
Spermatogenesis phases (multiplication, growth, maturation, spermiogenesis), oogenesis (fetal stage onwards), primary vs secondary oocyte, polar bodies.
Menstrual Cycle
28-day cycle phases (menstrual, follicular/proliferative, ovulatory, luteal/secretory), hormonal regulation (FSH, LH, estrogen, progesterone), ovulation on day 14.
Fertilisation & Implantation
Fertilisation in ampulla, acrosome reaction, zona pellucida, cortical reaction, cleavage, blastocyst formation, implantation in endometrium.
Pregnancy & Placenta
Placental formation (chorion + decidua), placental hormones (hCG, hPL, estrogen, progesterone, relaxin), placental barrier, umbilical cord structure.
Embryonic Development
First trimester landmarks, second trimester movements, third trimester organ maturation, amnion and amniotic fluid functions.
Parturition & Lactation
Oxytocin and foetal ejection reflex, uterine contractions, role of prolactin in lactation, colostrum composition, advantages of breastfeeding.
Question Type Distribution
| Question Type | Share (approx) | Example Pattern |
|---|---|---|
| Structure/Diagram Identification | 25% | Identify the labelled structure in the cross-section of testis. |
| NCERT-Line Recall | 30% | Where in the female reproductive tract does fertilisation normally occur? (ampulla) |
| Hormonal Regulation | 20% | Which hormone peaks just before ovulation? (LH) |
| Menstrual Cycle Timing | 10% | What happens in the endometrium during the luteal phase? |
| Embryonic Development Stage | 10% | At what stage does implantation in the uterus occur? (blastocyst) |
| Placenta & Pregnancy Hormones | 5% | Which hormone does early pregnancy tests detect? (hCG) |
How to Solve Human Reproduction PYQs
- 1Master the reproductive system diagrams. Testis cross-section, ovary cross-section, Graafian follicle, menstrual cycle hormonal chart. These are NCERT figures — drawable from memory is the target.
- 2Learn the menstrual cycle day-by-day. Day 1: menstruation starts. Day 5: follicular phase begins. Day 14: ovulation. Day 15–28: luteal/secretory. Know hormone peaks at each phase.
- 3NCERT cross-reference every PYQ. NEET Human Reproduction is NCERT-line-heavy. For each wrong answer, find the exact NCERT line and underline it.
- 4Gametogenesis: track the chromosome numbers. Spermatogenesis: 2n → 2n → n → n (via meiosis). Oogenesis: arrested stages, ends with polar bodies + one ovum. Quantities matter in PYQs.
- 5Placenta PYQs: focus on hormones. hCG (early), hPL (growth), estrogen + progesterone (maintenance), relaxin (birth prep). Match hormone to function.
Common Mistakes That Cost Marks
- Wrong chromosome number in secondary oocyte. Secondary oocyte is haploid (23 chromosomes), arrested in metaphase II until fertilisation. Not diploid.
- Confusing follicular and luteal phase hormones. Follicular phase: FSH dominant, estrogen rises. Luteal phase: LH initially, progesterone dominant.
- Placement of fertilisation. Fertilisation happens in the ampulla of the fallopian tube (not in the uterus). Implantation happens in the uterus. Different locations.
- Wrong timing of ovulation. Standard 28-day cycle: ovulation on day 14. In longer/shorter cycles, it's not always day 14 — ovulation is typically 14 days BEFORE next menstruation, not 14 days after.
- Treating placental hormones as maternal. hCG, hPL, relaxin — all produced by placenta, not by maternal glands. Pre-placental pregnancy hormones (LH, FSH) are maternal.

Frequently asked questions
How many Human Reproduction PYQs should I solve?
Target 80+ Human Reproduction PYQs across NEET 2020 to NEET 2025. Given the ~4% weightage plus visual/diagram intensity, focused practice here gives strong mock score returns.
Is NCERT Class 12 Chapter 3 enough for this chapter?
Yes — NCERT Ch 3 (Human Reproduction) + chapter PYQs is sufficient for 20+/20 in this chapter. NCERT's diagrams and hormonal cycle charts are exactly what NTA asks from.
What's the most-tested Human Reproduction PYQ template?
Menstrual cycle phase identification + hormonal profile matching. Roughly 40% of PYQs test this. Master the day-by-day cycle + hormone peaks and you lock in these marks.
Do I need to memorise every accessory gland?
Yes for male reproductive system: seminal vesicle, prostate gland, bulbourethral glands (Cowper's). Know their location and the percentage contribution to semen volume. Direct NCERT recall.
How detailed should embryonic development knowledge be?
Monthly landmarks only — first trimester (implantation, organogenesis, heartbeat), second (movements, gender), third (lung maturation, growth). Week-by-week detail is coaching-overkill for NEET.
Are placental hormones tested separately or together?
Both — NEET asks for hormone identification (hCG = placenta) and also function questions (which hormone causes relaxation of pelvic ligaments before birth = relaxin). Memorise function pairs, not just names.
