Transgender hormone therapy (male-to-female) orchiectomy still experience morning erections. Voluntary erections may or may not be possible, depending on the amount of hormones and/or antiandrogens being taken. Managing long-term hormonal regimens have not been studied and are difficult to estimate because research on the long-term use of hormonal therapy has not been noted. However, it is possible to speculate the outcomes of these therapies on transgender people based on the knowledge of the current effects of gonadal hormones on sexual functioning in cisgender men and women. Firstly, if one is to decrease testosterone in male-to-female gender transition, it is likely that sexual desire and
Melanocyte-stimulating hormone when the animal is in a dark location. This causes pigment to be dispersed in pigment cells in the toad's skin, making it become darker, and harder for predators to spot. The pigment cells are called melanophores and therefore, in amphibians, the hormone is often called melanophore-stimulating hormone. An increase in MSH will cause darker skin in humans too. MSH increases in humans during pregnancy. This, along with increased estrogens, causes increased pigmentation in pregnant women. Cushing's disease due to excess adrenocorticotropic hormone (ACTH) may also result in hyperpigmentation, such as acanthosis nigricans in the axilla. Most people with primary
