 (a) CuT
 (b)”Saheli”

Answer 1

Hint:A copper IUD was one of the first types, highly efficient and effective long-term birth control for women who wished to control their fertility. “Saheli” is an oral contraceptive pill.

Complete answer:
The tool or devices used to prevent pregnancy are birth control, also known as contraception and fertility control. Birth control has been in use since old times, but in the 20th century reliable and effective methods of birth control were only feasible. Family planning is referred to as planning, making available and utilizing birth control. Some societies restrict or discourage access to birth control because they view it as unwelcome in terms of morale, faith or politics. The WHO and the U.S. Centers for Disease Control and Prevention offer information on birth control protection for women with specialized medical conditions.
Usually, copper IUDs are made of plastic with some sections coated in exposed copper. Women had little long-term possibility for safe and safe birth control before the invention of the first IUDs. These solutions were primarily barrier approaches and an oral birth control pill, which only operated when properly and regularly used. A copper IUD was one of the first types, highly efficient and effective long-term birth control for women who wished to control their fertility. It did not require continuous, persistent action on the part of women to remain effective. Copper IUDs avoid conception by disordering the design process when a fertilised zygote forms by the male sperm and the female egg. Conception can only occur when an egg from one of her ovaries is released from her body by a process known as ovulation every 28 days.
Saheli is the latest oral contraceptive pills that provide a non-steroidal preparation for the females. It is a pill 'once a week' with very few side effects, high contraceptive benefits. Since it does not have any hormones, Saheli is different from other birth control pills. It contains a drug which blocks the receptors of estrogen, rather than using the hormone estrogen to avoid pregnancy. Increased estrogen doses normally prevent the release of an egg by a woman. However, Saheli alters the uterus lining by blocking estrogens in the uterus which stops the implantation of fertilised eggs.

Note:Sterilization by vasectomy in men and by tubal ligation in women, intrauterine devices (IUDs) and implanted birth control are the most powerful methods of birth control. There are many approaches dependent on hormones, including oral tablets, patches, vaginal rings and injections.
