CBSE Class 12 Biology Chapter 3 Revision Notes
Chapter 3: Reproductive Health
Introduction:
- Reproductive health refers to the overall well-being and proper functioning of the reproductive system in individuals and communities.
- It encompasses various aspects, including sexual health, family planning, prevention and management of reproductive disorders, and ensuring safe and responsible sexual behaviour.
Sexually Transmitted Infections (STIs):
- STIs are infections transmitted through sexual contact and can cause significant health issues.
- Common STIs include HIV/AIDS, syphilis, gonorrhea, chlamydia, genital herpes, and human papillomavirus (HPV) infection.
- Preventive measures, such as abstinence, practicing safe sex, and regular testing, are essential to reduce the spread of STIs.
Contraception and Family Planning:
- Contraception methods help individuals and couples plan and control their family size.
- Barrier methods (e.g., condoms), hormonal methods (e.g., birth control pills), intrauterine devices (IUDs), and surgical methods (e.g., tubal ligation, vasectomy) are commonly used contraceptive options.
- Family planning programs promote awareness, accessibility, and affordability of contraceptive methods to ensure reproductive choices.
- Vasectomy- Small part of vasa deference cut and tied up
- Tubectomy- Small part of the fallopian tube is cut and tied up
Medical Termination of Pregnancy (MTP):
- MTP, also known as abortion, is the deliberate termination of pregnancy before the fetus is viable.
- It should be performed by qualified healthcare professionals in safe and legal conditions to prevent health risks and complications.
- MTP should be carried out within the legal gestational limits set by the respective country’s laws.
- Safe during the first trimester
Assisted Reproductive Technologies (ARTs):
- ARTs are techniques used to assist individuals and couples in achieving pregnancy when natural methods are not successful.
- In vitro fertilisation (IVF), intracytoplasmic sperm injection (ICSI), gamete intrafallopian transfer (GIFT), and surrogate motherhood are examples of ART procedures.
- Ethical considerations and regulations are important in ensuring the responsible and ethical use of ARTs.
Reproductive Disorders and Prevention:
- Various reproductive disorders can affect both males and females, such as infertility, sexually transmitted infections, menstrual disorders, and reproductive cancers.
- Awareness, early diagnosis, and preventive measures like vaccination (e.g., HPV vaccine) and regular health check-ups are essential to manage and prevent reproductive disorders.
