How does ICSI differ from traditional insemination methods?

ICSI involves directly injecting a sperm into an ovum, making it suitable for cases with low sperm counts or male infertility issues. Signup and view all the answers

What is the significance of assisted reproductive technologies for infertile couples?

ART provides hope for infertile couples by enabling pregnancies that might not be possible through natural methods and allows for freezing embryos for future use. Signup and view all the answers

List two methods of artificial insemination and explain how they differ.

Intrauterine insemination (IUI) and intracervical insemination (ICI) differ in that IUI deposits sperm directly into the uterus, while ICI deposits it in the cervix. Signup and view all the answers

Study Notes

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.
