Reproductive Health: Class 12 Biology Chapter 4 Essential Guide

Reproductive Health ka matlab sirf bacho ka janm dena nahi hota, balki iska matlab hai ki ek insaan physically, emotionally, behaviorally, aur socially bilkul fit ho. Bharat duniya ka pehla aisa desh tha jisne 1951 mein "Family Planning" program shuru kiya tha.

1. Reproductive Health: Problems aur Strategies

Sarkar ne RCH (Reproductive and Child Health Care) programs shuru kiye hain taaki:

  • Logon ko Sexually Transmitted Diseases (STDs) ke baare mein bataya ja sake.

  • Schools mein Sex Education ko badhava diya jaye.

  • Maa aur bache ki health (Post-natal care) par dhyan diya jaye.

  • Amniocentesis (fetal sex determination test) par ban lagaya gaya hai taaki female foeticide (kanya bhrun hatya) ko roka ja sake.

2. Population Explosion aur Birth Control

Duniya ki population bahut tezi se badh rahi hai, jisse bachne ke liye Contraceptive Methods (garbh-nirodhak tarike) ka upyog zaroori hai.

Main Contraceptive Methods:

  1. Natural Methods: Periodic abstinence (10-17 din tak milan na karna), Coitus interruptus, aur Lactational amenorrhea.

  2. Barrier Methods: Condoms aur Diaphragms ka use karna jo sperm aur ovum ko milne se rokte hain.

  3. IUDs (Intra Uterine Devices): Yeh doctor dwara uterus mein fit kiye jate hain (e.g., CuT, Cu7, Multiload 375).

  4. Oral Contraceptives: Pills jaise ki Saheli, jo Lucknow (CDRI) mein banayi gayi thi. Yeh non-steroidal aur "once-a-week" pill hai.

  5. Surgical Methods (Sterilization): Yeh permanent tarika hai.

    • Vasectomy: Males mein Vas deferens ko block karna.

    • Tubectomy: Females mein Fallopian tube ko block karna.

3. Medical Termination of Pregnancy (MTP)

MTP ka matlab hai waqt se pehle (voluntary) pregnancy ko khatam karna.

  • Bharat mein ise 1971 mein legalize kiya gaya tha lekin sakht rules ke saath.

  • MTP pehle 12 weeks (first trimester) tak sabse safe maani jati hai.

4. Sexually Transmitted Diseases (STDs)

Jo bimariyan sexual contact se phailti hain unhe STDs ya Veneric Diseases (VD) kehte hain.

  • Examples: Gonorrhea, Syphilis, Genital herpes, Chlamydiasis, Hepatitis-B, aur sabse khatarnak AIDS.

  • Prevention: Unknown partners ke saath contact se bachein aur hamesha protection ka use karein.

5. Infertility aur ART (Assisted Reproductive Technologies)

Jab koi couple natural tarike se bache paida nahi kar paata, toh unhe Infertility kehte hain. Iske liye modern technology (ART) ka sahara liya jata hai:

  • IVF (In-Vitro Fertilization): Jise "Test Tube Baby" bhi kehte hain. Lab mein fertilization ke baad embryo ko transfer kiya jata hai (ZIFT ya IUT).

  • GIFT (Gamete Intra Fallopian Transfer): Ovum ko un females mein transfer karna jo khud egg produce nahi kar sakti.

  • ICSI (Intra Cytoplasmic Sperm Injection): Direct sperm ko egg mein inject karna.

  • AI (Artificial Insemination): Agar male ka sperm count kam ho, toh use lab mein female ke andar dala jata hai.
