Results from this study4

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone4

In this study, Triptorelin (Trelstar, Decapeptyl) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Triptorelin (Trelstar, Decapeptyl).

    Summary · context
    HFD induced hypogonadotropic hypogonadism is characterized by a reduction of plasma T, FSH, LH levels, testis and seminal vesicles weight, and testicular steroidogenic enzymes.
    Summary · context
    Male rabbits fed a high-fat diet (HFD), with or without testosterone (T) supplementation, were compared with control rabbits (fed a standard chow) and with rabbits made hypogonadal by a single injection of a long-acting GnRH-analog, triptorelin.

    HFD also induced penile alterations, as demonstrated by a reduction of acetylcholine-and electrical field stimulation-induced CC relaxation, hyper-responsiveness to the NO donor, SNP, and unresponsiveness to PDE5 inhibitors.
