B. Stops fertilization
C. Stops zygote formation
D. Stops obliteration of blastocoel

Answer 1

Hint: Copper T is a method to prevent unwanted pregnancy ie generally sexual activity without the use of any effective contraception through choice is the main cause of unwanted pregnancy.

Complete answer:
-Copper T is defined as an intrauterine device (IUD) which is commonly referred to as the copper coil containing copper. The device is applicable in several birth control measures and emergency contraception procedures within the first five days of undergoing sexual intercourse.
-This device is implanted into the uterus upto 12 years. Womens of all ages can make the best use of this device irrespective of whether they have or do not have children. Once removed, fertility quickly returns back to its normal stage. A Copper- T or intrauterine device contains copper in it. The purpose of copper ions is to destroy the male reproductive cells. In the production of spermicidal effect copper ions act on the cervical mucus at the opening of the uterus.
-The copper T contains the copper ions which results in the inflammatory reaction in the uterus in which the sperm cannot enter the egg to fertilize it and develop into an embryo.
-Copper IUDs are CuT, Cu7, Multiload 375 which raises the phagocytosis of sperms in the uterus and the Cu ions formed decrease the sperm motility as well as fertilizing ability of sperm. It makes the uterus unsuitable for implantation and the cervix hostile to the sperms. It is the main contraceptive for females who do not want to be pregnant or want to have a gap in children.
-The intrauterine device releases copper ions with the female reproductive tract that inhibit the movement or mobility of sperm. As the mobility of the sperm is suppressed, fertilization does not happen. Sperm movement interferes with the copper ions, hence the IUD releasing copper acts as an effective contraceptive measure.

Hence, the correct answer is option (B).

Additional information:
There are different birth control methods:
-Natural birth control: which includes rhythm, continuous abstinence etc
-Barrier method: It includes condoms
-Surgical method: It includes vasectomy and tubectomy
-Hormonal method: It includes birth control pills, vaginal rings etc.
-Intrauterine devices: which includes copper IUD and hormonal IUD.

Note: Expulsion, perforation, infection, cramping, heavier period, irregular bleeding and spotting, string problems and pregnancy are the most common side effects of Copper T implantation.
