This attachment of the blastocyst to the endometrium is called implantation. 14. Answer : (a) Vasectomy Explanation: In a vasectomy, the vas deferens tubes are tied, cut, clipped, or sealed to prevent the release of sperm into the semen. This prevents a woman's egg from being fertilized with the man's sperm. 15.

In such situations, the ovum from the donor woman is transplanted into the fallopian tube of the women 22. Answer : (c) suppress sperm motility Explanation: IUDs increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilizing capacity of sperms. The hormone-releasing IUDs, in addition, make the uterus unsuitably for implantation and the cervix hostile to the sperms. 23. Answer : (b) Consap Explanation: Central drug research institute, Lucknow, India has developed spermicidal cream called Consap. It has the capability of killing the sperm released during insemination. 24. Answer : (a) Assisted Reproductive Technologies Explanation: Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility. This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), cryopreservation of gametes or embryos, and/or the use of fertility medication. 25. Answer : (c) Fallopian tube or uterus Explanation: In E.T techniques, embryos are always transferred into the uterus.
