Ovitrelle is a medicinal product containing choriogonadotropin alfa, which is very similar to chorionic gonadotrophin found naturally in humans, but it is made in laboratories by special recombinant DNA techniques. It belongs to the family of hormones called gonadotrophins, which are involved in the normal control of reproduction.
Ovitrelle is used in women undergoing assisted reproductive techniques such as in vitro fertilisation (IVF). Other medicines are given first to bring about the growth and development of several follicles, to produce eggs. Ovitrelle is then used to ripen (mature) these follicles.
Ovitrelle is also used in women who do not produce eggs (a condition called anovulation), or who produce too few eggs (oligo-ovulation). It is given to bring about the release of eggs (ovulation), after other medicines have been used to develop the follicles.
