Refractory period (sex) for treating sexual dysfunction. Sildenafil, used in the treatment of erectile dysfunction, was found in one scientific study to have caused "a decreased postejaculatory erectile refractory time (3.2 ± 0.7 vs. 6.4 ± 0.7 minutes)" in men diagnosed with premature ejaculation. It is additionally proposed that the gonadotropin inhibitory hormone (GnIH), which is considered to inhibit the hypothalamic-pituitary-gonadal axis and sexual functions causes refractoriness of the post-ejaculatory refractory period. This hypothesis also supports the increase of oxytocin and prolactin after orgasm in accordance with the previous studies. One alternative theory explains the male refractory period in terms of a peripheral
Adrenocorticotropic hormone (medication) per vial. As an off-patent pharmaceutical, a similar drug, differing in formulation, available in Europe, made by a different manufacturer, sells for $8 per vial. Acthar gel has been proposed as a therapy to treat refractory autoimmune diseases and refractory nephrotic syndrome due to a variety of glomerular diseases. Both versions of the hormone are also used to perform the ACTH stimulation test to diagnose hypoadrenocorticism in dogs and sometimes cats. Adrenocorticotropic hormone (medication) Adrenocorticotropic hormone is used as a medication and as diagnostic agent in the ACTH stimulation test. The form that is purified from pig pituitary glands is
