Hi WalkingArt,
I looked on the IVFAustralia site and found this..
FSH (Puregon) is a synthetic hormone which is exactly like a natural hormone but, being synthetic, it cannot carry any infectious agents. It is used to promote the growth of ovarian follicles and is administered as a subcutaneous (just under the skin) injection.
Reported Side Effects:
Headaches, tiredness and lethargy
Irritability and tearfulness
Breast tenderness
Nausea
Enlarged tender ovaries
Abdominal distension and discomfort
Fluid retention
OHSS
