Chapter Overview & Weightage
- Marks in Boards: 8–12 marks (highest in Reproduction unit – usually 2–3 questions + diagram)
- Repeated Topics: Male/female reproductive systems, gametogenesis (spermatogenesis/oogenesis), menstrual cycle, fertilization, implantation, placenta, parturition.
- Difficulty: Moderate to high • Heavy on diagrams (male/female reproductive system, sectional view of ovary/testis) + processes & hormones.
- Trend (2021–2025): 1 labelled diagram (5 marks) + 1 long answer (5 marks) on menstrual cycle/spermatogenesis + MCQs on hormones & events.
Most Important & Repeated Questions (2021–2025)
- Repeated 5–6 times: Draw a labelled diagram of sectional view of human male reproductive system. Label 8–10 parts. (5 marks)
- Repeated 5 times: Draw a labelled diagram of sectional view of human female reproductive system. Label 8–10 parts. (5 marks)
- Repeated 4–5 times: Explain spermatogenesis with diagram. Name hormones involved. (5 marks)
- Repeated 4 times: Describe oogenesis with diagram. Compare with spermatogenesis. (5 marks)
- Repeated 4 times: Explain menstrual cycle with diagram. Name hormones & their role in phases. (5 marks)
- Repeated 3 times: What is fertilization? Describe the process of implantation. (3 marks)
- Repeated 3 times: Explain role of placenta in human reproduction. (3 marks)
- Repeated 2–3 times: Describe parturition (birth process) and role of oxytocin. (3 marks)
- Assertion-Reason (2023–2025): Assertion: Spermatogenesis occurs in seminiferous tubules. Reason: Sertoli cells provide nourishment. (Both true, reason explains – repeated 2x)
Important Keywords & Concepts to Memorize
- Testis, seminiferous tubules, Sertoli cells, Leydig cells, epididymis, vas deferens, seminal vesicle, prostate, bulbourethral gland, scrotum, penis, ovary, oviduct (fallopian tube), uterus, cervix, vagina, Graafian follicle, corpus luteum, fimbriae, spermatogenesis, oogenesis, FSH, LH, testosterone, estrogen, progesterone, hCG, menstrual cycle (follicular, ovulatory, luteal phases), fertilization, cleavage, implantation, placenta, umbilical cord, parturition, oxytocin, relaxin.
Exam Strategy for Chapter 3 (2026 Boards)
- Focus: Diagrams (male/female reproductive system, sectional view of ovary/testis) – practice 4 daily
- High-scoring: Spermatogenesis/oogenesis/menstrual cycle (5 marks each) + labelled diagram
- Time: 8–10 minutes per 5-mark question (diagram + explanation)
- Tip: Label 8–10 parts in every diagram – neatness = full marks
- Repeated: Hormonal regulation of menstrual cycle (FSH, LH, estrogen, progesterone) – 3–5 marks
