STD-XII-A Biology: Reproductive Health and Population

Introduction

• Investigatory file submitted by Kaushiki Bhattacharya for STD-XII-A Biology at CWS Crimson World School, Agra.
• File covers reproductive health, population explosion, birth control, contraceptives, medical termination of pregnancy (MTP), sexually transmitted diseases (STDs), and infertility.
• The file was submitted to Pooja Ma'am.

Reproductive Health

• Defined as the state of physical, emotional, behavioural, and social well-being in all aspects of reproduction (physical, emotional, behavioural, and social).
• India was one of the first countries to implement family planning programs in 1951.
• Reproductive and child health care (RCH) programs are in operation.

Population Explosion and Birth Control

• Population explosion is the increase in size and growth of the human population.
• India's population was 350 million at independence and is now 1.39 billion (as of May 2020), making it the second most populated country. (17.7% of the world's population).
• Reasons for high population growth include declining death rates, longer lifespans, declining maternal and infant mortality rates, religious beliefs against birth control, and lack of reproductive health knowledge.

Contraceptive Methods

• Aim to prevent pregnancy through various methods like:
• Natural methods (like periodic abstinence, withdrawal)
• Barrier methods (like condoms, diaphragms)
• Intrauterine devices (IUDs)
• Oral contraceptives
• Injections/implants
• Surgical methods (like vasectomy and tubectomy)

Medical Termination of Pregnancy (MTP)

• Intentional or voluntary termination of pregnancy.
• Legalised in India in 1971, with strict restrictions on indiscriminate or illegal female foeticide.
• Safe within the first trimester (12 weeks); riskier in later stages.
• Restrictions, and legal guidelines, are in place to ensure safety.

Sexually Transmitted Diseases (STDs)

• Diseases transmitted through sexual intercourse (e.g., Gonorrhea, Syphilis, Genital Herpes, Chlamydiosis, genital warts, hepatitis B, HIV).
• Many STD's can be cured.
• Transmission factors include unprotected sex, multiple partners, needle reuse, blood transfusions.
• Symptoms may include itching, fluid discharge, pain, swelling in the genital region.
• Prevention includes avoiding sex with unknown partners, consistent condom use, and early diagnosis and treatment.

Infertility

• Inability of a couple to conceive despite unprotected sex.
• Factors include ovulation disorders, sperm count, uterine fibroids, infections, and more.
• Assisted reproductive technologies (ART) like IVF, ICSI, ZIFT, GIFT can be used to address infertility.
• These techniques are not always accessible and can be costly.

Methods to Control Infertility

• IVF (In Vitro Fertilization): Fertilization takes place outside the body and the embryo is transferred to the uterus.
• ZIFT (Zygote Intrafallopian Transfer): Fertilized egg is transferred to fallopian tube.
• GIFT (Gamete Intrafallopian Transfer): Unfertilized eggs and sperm transferred into fallopian tube.
• ICSI (Intra Cytoplasmic Sperm Injection): Injection of a sperm directly into the egg.
• AI (Artificial Insemination): Semen from partner/donor is introduced into the uterus.

Conclusion

• Importance of sexual and reproductive health awareness.
• Importance of open communication among family and friends.
• Necessity to combat STDs, and improve awareness of reproductive health.
• Acknowledgment of the role of the investigation in informing and educating young people about various techniques and procedures.
