Does combination gonadotropin-releasing hormone agonist and oral contraceptive therapy improve treatment of hirsute women with ovarian hyperandrogenism?
"Add-back" OC therapy used in combination with a GnRH-a increases SHBG and more effectively lowers free T levels in women with ovarian hyperandrogenism. Enhanced suppression of "bioavailable" androgens with combined GnRH-a and OC therapy failed to improve significantly the therapeutic effect of GnRH-a treatment alone on hirsutism.
This study reveals that the UCHL1 S18Y variant is a risk factor for sporadic PD. We could not find evidence for interactions affecting sporadic PD between UCHL1 S18Y and SNCA SNP rs356220, smoking, or caffeine intake.
