Puregon 300iu / 0.36ml, Puregon 600iu / 0.72ml and  Puregon 900iu / 1.08ml are solutions for injection that contain a hormone know as follicle-stimulating hormone (FSH) in a strength of 833 IU/ml.
FSH belongs to the group of gonadotrophins, which play an important role in human fertility and reproduction.

Puregon is used to treat infertility in either of the following situations:
• In women who are not ovulating, Puregon can be used to cause ovulation in women who have not responded to treatment with clomiphene citrate.
• In women undergoing assisted reproduction techniques, including in vitro fertilisation (IVF) and other methods, Puregon can be used to bring about the development of multiple follicles.
• In men who are infertile due to a hormonal deficiency, Puregon can be used for the production of sperm.
