Factors Affecting Population Growth and Trends

  • Birth rate increasing leads to population growth
  • Death rate is the opposite factor, also known as mortality
  • Mortality is the number of deaths per 1000 individuals in a year
  • Maternal mortality rate is the number of mothers who die during pregnancy per 1000
  • Infant mortality rate is the number of infants who die per 1000
  • Migration affects population growth, with immigration increasing and emigration decreasing population
  • Natural increase rate is calculated by subtracting deaths and emigration from births and immigration
  • India's growth rate from the 2011 census was less than 2%
  • Demographic transition stages include high birth and death rates in stage one, decreasing death rates and increasing birth rates in stage two, declining birth rates in stage three, and stable birth and death rates in stage four
  • Population pyramids show population trends, with triangular indicating growth, bell-shaped indicating stability, and urn-shaped indicating decline.

"RCH Program: Contraception for Population Control"

  • RCH stands for Reproductive and Child Health Care Program, aimed at stabilizing the population by addressing reproductive health.
  • The program focuses on prenatal sex determination, detection of genetic disorders like Down Syndrome, and cleft palate through ultrasound.
  • Population control measures include raising the marriageable age to 21 for males and 18 for females, incentivizing small families, and banning child marriage.
  • Motivating smaller families through contraceptive methods is crucial in preventing unwanted pregnancies and controlling population growth.
  • Natural contraceptive methods like periodic abstinence, coitus interruptus, and lactational amenorrhea are discussed for birth control.
  • Barrier methods like condoms, both male and female, are effective in preventing pregnancy and sexually transmitted diseases.
  • Diaphragms and cervical caps are additional barrier methods that block sperm from reaching the cervix, aiding in contraception.
  • Contraceptive methods should be effective, affordable, easily accessible, and have minimal side effects to encourage consistent use.
  • Government initiatives promote the use of condoms, including the popular brand Nirodh, to ensure widespread availability.
  • Educating individuals on various contraceptive methods and their features is essential in promoting responsible family planning and population control.

"Contraceptive Methods: Chemicals, Barriers, and IUDs"

  • The cervix is located near the cervix and has a small structure.
  • Chemical methods are used along with barrier methods before sexual intercourse.
  • Chemicals like zinc sulphate, boric acid, and citric acid are applied in jelly or cream form.
  • Barrier methods have a failure rate, which can be reduced by using intra-uterine devices (IUDs).
  • IUDs can be inert, copper-containing, or hormonal, inserted into the uterus by a doctor or nurse.
  • Copper IUDs cause phagocytosis of sperm due to copper ions released.
  • Hormonal IUDs work by altering the endometrium lining and thickening cervical mucus.
  • Hormonal pills contain synthetic hormones like progesterone and estrogen, taken daily or cyclically.
  • Non-steroid pills like Saheli are taken weekly to prevent ovulation and endometrium changes.
  • Injectables and implants, like Cyclofem and LNG 20, provide long-term hormonal contraception.

Sterilization Methods and STDs: A Summary

  • Hormonal steroid used for skin cells, which are lipid-based, injected in silicone cylinders for terminal sterilization method.
  • Surgical method known as tubectomy for females, vasectomy for males, involves cutting and sealing ducts to prevent sperm or ovum transport.
  • Procedure involves cutting vas deferens or fallopian tubes, blocking transport of sperm or ovum, ensuring sterility.
  • Sterilization method for males and females prevents sperm or ovum transport, reversible upon cessation.
  • STDs transmitted through unprotected sexual intercourse, blood transfusion, or from mother to fetus.
  • Bacterial STDs like gonorrhea caused by Neisseria gonorrhoeae, leading to inflammation in ducts.
  • Syphilis caused by Treponema pallidum, affecting genitals and potentially damaging nervous system.
  • Viral STDs like genital herpes, genital warts, hepatitis B, and AIDS, with genital warts being curable.
  • Protozoal infection like trichomoniasis more common in females, causing alkaline conditions leading to white discharge.
  • Infertility defined as inability to conceive after two years of unprotected sexual intercourse, can be due to impotence in males or other factors in females.

Understanding Infertility and Assisted Reproductive Techniques

  • Proper sperm motility is crucial, with 200 to 300 million sperm needed, 60% of which should have a proper shape and 40% motility.
  • Azoospermia indicates non-timely sperm motility issues, while Oligospermia refers to a low sperm count.
  • Ovulation irregularities in females, like oligo ovulation, can lead to fertility problems.
  • Blocked fallopian tubes and hypothyroidism are common female infertility issues.
  • Infertility can stem from various factors, including age, drug use, autoimmune diseases, and psychological conditions.
  • IVF, or In Vitro Fertilization, involves fertilizing eggs and sperm outside the body, with GIFT and IUT as follow-up techniques.
  • Artificial insemination is used for low sperm count or ejaculation issues, either in the vagina or uterus, known as intrauterine insemination (IUT).
  • GIFT involves transferring eggs to the fallopian tube for fertilization, while ICSI injects sperm directly into the ovum for fertilization.
  • ICSI is used when sperm morphology is poor, ensuring successful fertilization.
  • After fertilization, the embryo is transferred back to the uterus for implantation, potentially leading to pregnancy.

Assisted Reproductive Technologies and Pregnancy Termination

  • IVF involves fertilization outside the body under conditions similar to those inside the body, followed by embryo transfer, a popular method known as the Test Tube Baby Program.
  • Ova from the wife and donor, or sperm from the husband and donors, are collected and induced to form zygotes under laboratory conditions similar to those in the fallopian tube.
  • Embryos formed in vitro can be transferred into the fallopian tube or uterus through intrauterine transfer to complete their development.
  • In vitro fertilization can be used for embryo transfer to assist females who cannot conceive, allowing embryos to be created from one woman's uterus and transferred to another.
  • Intra Cytoplasmic Sperm Injection involves directly injecting sperm into the ovum to address infertility cases due to male partners' inability to produce semen or low sperm count.
  • Artificial insemination, such as Intrauterine Insemination (IUI), involves introducing semen collected from the husband or a healthy donor into the vagina and uterus, with IUI specifically done in the uterus.
  • Medical Termination of Pregnancy (MTP) is the intentional and voluntary termination of pregnancy before full term, legalized in India in 1971 and regulated by the MTP Act of 1975.
  • MTP is essential to address unwanted pregnancies due to casual unprotected sexual intercourse, failure of contraception, or when continuation of pregnancy could be harmful or fatal to the mother.
  • MTP is relatively safe during the first trimester, up to 12 weeks of pregnancy, with restrictions in place to prevent misuse and ensure safety.
  • Different methods, including drug administration, surgical procedures, and saline infusion, are used for MTP, with strict regulations and guidelines in place to ensure safety and legality.

Reproductive Anatomy and Birth Control Methods

  • Implantation occurs in the fallopian tube, not the cervix, as the ovum is caught there.
  • Vasectomy involves cutting the vas deferens, leading to sterility by preventing sperm from entering the seminal fluid.
  • Barrier methods like intrauterine devices increase phagocytosis of sperm, suppress sperm motility, and prevent fertilization.
  • Ectopic pregnancies involve implantation of the embryo in the fallopian tube, leading to termination of pregnancy due to implantation defects.
