Reproductive Health - NEET 2026 Complete Notes

1. Need for Reproductive Health

Definition:

Reproductive health is defined by the WHO as a state of complete physical, mental, and social well-being in all matters relating to the reproductive system, not merely the absence of disease or infirmity.

Why It’s Important:

1. Population Control: India faces overpopulation pressure. Reproductive health promotes awareness and use of contraceptives to regulate birth rates.
2. Maternal and Child Health: Ensures safe pregnancy, delivery, and postnatal care, reducing infant and maternal mortality.
3. STD Prevention: Promotes safe sexual practices to stop spread of diseases like HIV, Syphilis, Gonorrhea.
4. Contraceptive Awareness: Educates people on choices available for birth control, and safe spacing between pregnancies.
5. Infertility Diagnosis and Treatment: Helps couples struggling with conception by providing medical assistance and counseling.
6. Sexual Education: Helps teenagers understand puberty, menstruation, pregnancy, and personal safety.

📌 Government initiative: RCH Programme (Reproductive and Child Health care) launched to improve reproductive well-being across India.

2. Sexually Transmitted Diseases (STDs)

Definition:

STDs are infections transmitted through sexual contact. They can be bacterial, viral, or protozoan.

Common STDs and Causative Agents:

NEET Tip: Match diseases with causative agents and transmission mode.

Prevention of STDs:

• Use latex condoms during intercourse
• Avoid multiple sexual partners
• Get vaccinated (Hepatitis B, HPV)
• Regular medical checkups and early treatment
• Avoid unprotected sex and sharing of needles

3. Birth Control – Need and Methods

Why Birth Control?

• Prevent unintended pregnancies
• Avoid illegal and unsafe abortions
• Maintain spacing between births
• Prevent transmission of STDs
• Contribute to population stabilization

4. Contraceptive Methods

Classification of Contraceptives:

Natural Methods:

• Periodic Abstinence (Rhythm Method): Avoid intercourse during fertile window (days 10–17 of menstrual cycle).
• Withdrawal (Coitus Interruptus): Penis withdrawn before ejaculation.
• Lactational Amenorrhea: During lactation, prolactin suppresses ovulation temporarily.

📌Less effective due to dependency on self-control and body awareness.

Barrier Methods:

• Male/Female Condoms: Prevent semen from entering the female tract.
• Diaphragms, Cervical caps: Inserted into vagina to cover cervix; used with spermicides.

📌Protect against both pregnancy and STDs.

Intrauterine Devices (IUDs):

• Non-medicated: Lippes Loop (mechanical barrier)
• Copper-releasing (CuT, Cu7): Copper ions reduce sperm motility
• Hormone-releasing (Progestasert, LNG-20): Progesterone prevents endometrial buildup, thickens mucus.

📌Inserted by trained doctor; long-term reversible method.

Hormonal Methods:

• Combined Pills: Contain estrogen + progesterone; inhibit LH & FSH, hence no ovulation
• Saheli (India): Non-steroidal pill (centchroman); once-a-week, high safety margin

Surgical Methods (Sterilization):

• Vasectomy: Vas deferens cut and sealed in males; no sperm in semen
• Tubectomy: Fallopian tubes cut/tied in females; prevents ovum transport

📌Permanent, irreversible; advised for couples with completed families.

5. Medical Termination of Pregnancy (MTP)

Definition:

Deliberate termination of pregnancy before full term using medical/surgical methods.

Legal Aspects in India:

• Legal under the MTP Act (1971), amended in 2021
• Can be done up to 24 weeks in specific cases:
• Risk to mother’s health
• Fetal abnormalities
• Pregnancy due to rape/incest
• Failure of contraceptives (in married and unmarried women)

Methods:

• Medical MTP: Drugs like mifepristone + misoprostol
• Surgical MTP: Dilation and curettage (D&C), vacuum aspiration

 📌Risks include incomplete abortion, infections, future complications. Should be conducted only by qualified licensed practitioners.

6. Amniocentesis

What Is It?

A diagnostic technique where amniotic fluid is drawn using a needle (14–16 weeks pregnancy) to analyze fetal cells.

Applications:

• Detect chromosomal abnormalities (Down’s syndrome, Turner’s syndrome)
• Identify metabolic/genetic disorders (Thalassemia, Sickle cell)
• Determine fetal sex (❌ illegal in India under PCPNDT Act)

📌 Misuse for sex-determination → female foeticide → strict ban

🚫 7. Infertility

Definition:

Inability of a couple to conceive even after 1 year of regular, unprotected sex

Causes:

In Males:

• Low sperm count (oligospermia)
• Poor motility
• Hormonal imbalance (↓ testosterone)
• Obstruction in vas deferens
• STDs or varicocele

In Females:

• Ovulation failure (due to PCOS, hormone imbalance)
• Blocked fallopian tubes
• Endometriosis
• Uterine abnormalities
• Thyroid disorders

Diagnosis:

• Hormone assays (FSH, LH, TSH)
• Ultrasound, Hysterosalpingography
• Semen analysis
• Laparoscopy

8. Assisted Reproductive Technologies (ARTs)

ARTs are helpful for infertile couples, especially in:

• Blocked fallopian tubes
• Low sperm count
• Hostile cervical mucus
• Unexplained infertility

Final NEET Revision Points:

• Learn causative agents + symptoms of STDs
• Know mechanism and examples of contraceptives
• Understand MTP law and ART procedures
• Amniocentesis = prenatal diagnosis, not for sex determination!
