Antagonist

GnRH antagonists are a type of medication we use to suppress the pituitary gland without causing any initial stimulation. They are usually given in our clinic on day 5. Antagonists can simplify the stimulation regime and lessen the time required to complete the cycle.

Embryo

A developed fertilised egg between days 2 - 6

FSH

Follicle Stimulating Hormone is one of a set of gonadotrophs synthesised by the anterior pituitary gland in the brain. It regulates reproductive processes in the body and acts synergistically with LH (luteinising hormone). http://en.wikipedia.org/wiki/Follicle-stimulating_hormone

Oocyte

Also called egg or ovum. This is the female germ cell involved in reproduction. It is produced in the ovary during each monthly cycle of the female.

Orgalutran

Orgalutran is used to pervent premature LH surges in women undergoing controlled ovarian hyperstimulation (as in IVF). It is a type of GnRH antagonist. This LH surge will lead to ovulation. Orgalutran is normally administered on day 7 of your stimulation cycle.
