Assisted reproductive technology, IVF involves transfer of
(a) ovum into the Fallopian tube
(b) zygote into the Fallopian tube
(c) zygote into the uterus
(d) embryo with 16 balastomeres into the Fallopian tube
(b) In vitro fertlisation is a process in which an egg is fertilised by sperm outside the woman's womb. IVF is a major treatment for infertility. The process involves hormonally controlled ovulatory process, removing ova from the woman's ovaries and letting sperm fertilise them in fluid medium. The zygote or the embryo up to the 8-celled stage is then transferred into the patient's Fallopian tube with the intent to establish successful pregnancy. When the zygote is more than 8 blastomere stage, it is placed directly into the uterus.
