Vasectomy involves cutting down vas deferens in males.
Generally, chances of conception are nil until the mother breast-feeds the infant for a period of a maximum of up to six months.
Intrauterine devices like copper-T are very effective contraceptives.
Emergency contraceptive pills may be taken up to one week after coitus to prevent conception.
Correct Statements:
2) Generally, chances of conception are nil until the mother breast-feeds the infant for a period of a maximum of up to six months.
3) Intrauterine devices like copper-T are very effective contraceptives.
Explanation:
1) Vasectomy involves cutting down vas deferens in males: This statement is incorrect. Vasectomy is a surgical procedure performed on males to prevent the release of sperm during ejaculation. It involves cutting or blocking the vas deferens, the tubes that carry sperm from the testicles to the urethra. It is a permanent method of contraception and does not involve females.
2) Generally, chances of conception are nil until the mother breast-feeds the infant for a period of a maximum of up to six months: This statement is correct. Breastfeeding can act as a natural contraceptive method for a certain period of time. It is known as lactational amenorrhea method (LAM). When a woman breastfeeds her baby exclusively (no other food or drink) and frequently, it suppresses ovulation and prevents the release of eggs from the ovaries. This can provide effective contraception for up to six months after childbirth.
3) Intrauterine devices like copper-T are very effective contraceptives: This statement is correct. Intrauterine devices (IUDs) are highly effective long-acting reversible contraceptives. Copper-T is a type of IUD that is inserted into the uterus to prevent pregnancy. It works by releasing copper ions that interfere with sperm function and prevent fertilization. Copper-T can provide contraception for up to 10 years and has a high success rate in preventing pregnancy.
4) Emergency contraceptive pills may be taken up to one week after coitus to prevent conception: This statement is incorrect. Emergency contraceptive pills, also known as "morning-after pills," are intended for use within a few days after unprotected intercourse or contraceptive failure. The effectiveness of these pills decreases over time, and they are most effective when taken as soon as possible after unprotected sex. Generally, emergency contraceptive pills should be taken within 72 hours (3 days) after coitus for maximum effectiveness. There are also some types of emergency contraceptive pills that can be taken up to 120 hours (5 days) after coitus, but their effectiveness decreases with time.
Therefore, the correct statements are 2) Generally, chances of conception are nil until the mother breast-feeds the infant for a period of a maximum of up to six months and 3) Intrauterine devices like copper-T are very effective contraceptives.

In males during vasectomy, a small part of the vas deferens is removed or tied up through a small incision on the scrotum, whereas, in females during tubectomy, a small part of the fallopian tube is removed or tied up through a small incision in the abdomen or through the vagina.
The lactational amenorrhoea (absence of menstruation) method is based on the fact that ovulation and, therefore, the menstrual cycle does not occur during the period of intense lactation following parturition. Therefore, as long as the mother breastfeeds the child fully, the chances of conception are almost nil. However, this method has been reported to be effective only up to a maximum period of six months following parturition.
IUDs increase phagocytosis of sperms within the uterus, and the Cu ions released suppress sperm motility and the fertilizing capacity of sperms, and thus are effective contraceptives.
Administration of progestogens or progestogen-estrogens combinations or IUDs within 72 hours of coitus has been found to be very effective as emergency contraceptives as they could be used to avoid possible pregnancy due to rape or casual unprotected intercourse.
