Chapter on "Birth Control--Technical Aspects." He divides them by male or female used.
Male: Says that coitus interruptus is probably still the most widely used today, "because it requires no apparatus or preparation, costs nothing, and is always available." Says it works for those who are disciplined in approach, but some question its effect on health and mental health.  "Some go to the extent of dismissing this method as being the easiest way to make husbands and wives nervous wrecks."
Karezza, or coitus reservatus is based on prevention of orgasm during sex, popularized by Alice Stockham and the Oneida community. Says that there is division over whether this too is unhealthy, but all agree that it requires "men of sound and well balanced nervous systems."
 Sheath, extensively deployed for venereal disease prevention, Chandrasehkar calls it a "satisfactory, reliable and harmless method. But the sheaths may be of an inferior quality or defective. Sometimes the method may cause physical discomfort or interfere with normal sexual response."
General objection to all these methods is that "they make the woman dependent on the man for protection in a matter that affects her own health most vitally. Should the husband be indifferent or careless or in an irresponsible position, the wife subjects herself to grave risks. This is one of the reasons wh methods  for the prevention of conception which can be used by the wife are generally considered to be the methods of choice today.
Chemical methods: Notes that there are contraceptive jellies, which while "effective in preventing conception, it is not absolutely reliable. In fact there is no chemical contraceptive which is completely reliable and effective."
Best method prescribed in England and US is the diaphragm and jelly, individually fitted to the woman, requires gynecological visit for proper fit; easy to teach, and "highly reliable and satisfactory method." Does not interfere with marital life; doesn't impair future fertility.  "But the difficulties of this method in Indian conditions can be readily seen. As the method involves an individual medical examination and instruction, requiring a competent doctor within the reach of  rural and urban mothers, the cost in setting up the necessary clinics and providing them with doctors and equipment would be prodigious. Even after this initial expenditure, there is no guarantee that needy mothers could afford the cost of the necessary equipment, even if the clinic consultation were free. Shocking as it may seem, in many rural areas the cost of having a baby would be cheaper than the price of birth control equipment. Unless and until the Government is prepared not only to give free clinical advice but also to supply equipment free of cost this particular method cannot be acceptable to the average rural mother in India."
 Sterilization is the cheapest and safest method of birth control today. Both men and women can be sterilized; male surgery (vasectomy) is simpler, but the women's (salpingectomy) is relatively major operation. Doesn't impact sex instinct or pleasure. Superstition in the country that there is a "un-sexing effect on the male. This of course is not true." Any father of 2 or 3 (or any man) can undergo the operation; should he lose his children, of course, he could not have more. But the fact that he has decided to have only 2 or 3  enhances their survival chances. If his wife dies and he remarries, he cannot have children with the new wife. But again, this will be less likely to happen if women are not constantly bearing children. It should be chosen voluntarily by men who want a technique of permanent conception control, as it is usually impossible to undo. In "cases of epilepsy, insanity, leprosy or mental defectiveness, the state might explore the possibility of compulsory sterilization as an eugenic measure. This would prevent the transmission of undesireable genes and the quality of the population could thus eventually be raised."
Biological Contraceptives Research being done on a biological contraceptive,  which would work on "the prevention of either ovulation, spermatogenesis, fertilization or the implantation of the fertilized egg. Also work done on "inducing temporary sterility in the female through hormonal control." Animal studies are underway. Also work done on Native American plant (lithosperm) that seems to control fertility. Pill is under study in the U.S., "It has to be taken for twenty days of the menstrual cycle. Secondly, the pill is very expensive. It is not realistic to expect mothers in India and other underdeveloped countries to be able to afford these pills even if they were available, or to have the necessary discipline to take them regularly." They need a cheap pill "which need be taken only once or twice for the desired conception control."
