Artificial insemination involves
A. Superovulation
B. Semen collection
C. Egg collection
D. Embryo collection

Hint: Sometimes a man’s sperm is not mobile enough to travel to the fallopian tube where an egg is fertilized. In such cases, Artificial insemination is recommended. Artificial insemination is a fertility treatment method in which sperm is delivered directly to the cervix or uterus for increasing chances of getting pregnant. These sperms are sometimes washed or “prepared” to increase the likelihood that the woman gets pregnant.

Complete answer:
Option A - Superovulation: Superovulation is the process of inducing a woman to release more than one egg in a month by controlled ovarian hyperstimulation. It can be achieved by administering follicular stimulating hormone (FSH) to donors twice daily for \[3\] - \[4\] days. The process of artificial insemination does not include superovulation.
Hence option A is not correct.
Option B - Semen collection: The process of obtaining semen from a donor with the help of various methods, for the purposes of artificial insemination, or medical study is termed as semen collection. For sperms to be directly introduced into the cervix or uterus, semen should be collected.
So, the correct answer is option B.
Option C - Egg collection: Egg collection or oocyte retrieval, is a technique which is used in in-vitro fertilization (IVF) in order to remove oocytes or eggs from the ovary of a woman, which enables the process of fertilization outside the body. This procedure is not done for artificial insemination.
Hence option C is not correct.
Option D - Embryo collection: An embryo is the early stage of development of a multicellular organism, where formation of body structures, such as tissues and organs take place. There is no such procedure as embryo collection in humans but embryo transfer is widely used. Assisted reproduction technique in which a developed embryo is placed into the uterus of a female with the intent to establish a pregnancy is known as embryo transfer.
Hence option D is also not correct.

Hence, Option B. Semen collection is the correct answer.

Note:
Women who desire to give birth to their own child who might be single. Women who are in a lesbian relationship or those women who are in a heterosexual relationship. But if the male partner is infertile or has some physical impairment which prevents them from full intercourse taking place, they are the beneficiaries of an artificial insemination procedure.
