Class 12 Biology - HARYANA
Reproductive Health
The chapter 'Reproductive Health' in Class 12 Biology focuses on the significance of maintaining reproductive well-being, the prevention of sexually transmitted infections (STIs), and strategies for population control. For Haryana (BSEH) board exams, students must understand various birth control methods, Assisted Reproductive Technologies (ART) like IVF and ZIFT, and the Medical Termination of Pregnancy (MTP). This chapter is crucial as it carries direct, scoring questions ranging from short-answer definitions to detailed explanations of contraceptive devices and infertility treatments, making it a high-yield topic for board preparation.

Amniocentesis
A fetal sex determination and genetic disorder test using amniotic fluid, which is legally banned in India to prevent female foeticide.
Contraceptive Methods

Medical Termination of Pregnancy (MTP)
Intentional or voluntary termination of pregnancy before full term, safe during the first trimester (up to 12 weeks) when performed by trained personnel.
Assisted Reproductive Technologies (ART)
Specialized techniques to help infertile couples have children, including IVF-ET, ZIFT, GIFT, ICSI, and Artificial Insemination (AI).

Frequently Asked Questions
What is the difference between tubectomy and vasectomy?
Tubectomy is a permanent birth control method in females where a small part of the fallopian tubes is removed or tied up. Vasectomy is the surgical sterilization method in males where a small part of the vas deferens is cut or tied.
Why is amniocentesis banned in India?
Amniocentesis is legally banned to prevent female foeticide and misuse for sex-determination, though it was originally developed to detect genetic disorders in the fetus.
What does ZIFT stand for and how is it different from GIFT?
ZIFT stands for Zygote Intra-Fallopian Transfer, where the zygote up to an 8-blasted stage is transferred to the fallopian tube. GIFT stands for Gamete Intra-Fallopian Transfer, where ovum is transferred into the fallopian tube of a female who cannot produce one.
