The Uses of Hormones to Treat Infertility Flashcards

All 5 cards in this deck

Which two hormones are given in a 'fertility drug', and why?: FSH and LH, to stimulate eggs to mature so the woman may become pregnant in the normal way.
In IVF, at what stage of development are embryos inserted into the mother's uterus, and how many?: When they are tiny balls of cells; one or two embryos are inserted.
Give three disadvantages of IVF treatment.: It is very emotionally and physically stressful, success rates are not high, and it can lead to multiple births which are a risk to both the babies and the mother.
True or false? In IVF the eggs are fertilised inside the mother's oviduct.: False. The eggs are collected from the mother and fertilised by the father's sperm in the laboratory.
True or false? A woman treated with a fertility drug containing FSH and LH may become pregnant in the normal way.: True. The hormones cause eggs to mature and be released, so fertilisation can happen inside her body.
