In vitro fertilization is commonly used for treating infertility. One stage of this process is controlled hyperstimulation of the ovaries, achieved by administering gonadotropins. There are several stimulation protocols utilized that increase the number of ovarian follicles during IVF. The most common protocol employs desensitization - the inhibition of follicle-stimulating hormone and luteinizing hormone secretion by the pituitary gland. This is achieved by administering a gonadotropin-releasing hormone (GnRH) analog that is agonistic for the GnRH receptor. However the use of a this drug during therapy carries a risk of complications. This case report deals with a rare case of a woman who underwent pituitary tumor growth as a result of the treatment of GnRH analog.
