dihydrotestosterone造句
1 Genetic studies have shown that male pattern baldness (aka androgenetic alopecia, or common baldness) is caused by a sensitivity of hair follicles to a male sex hormone (dihydrotestosterone, or DHT). 2 The aim was to determine whether leels of total or free testosterone , dihydrotestosterone, and sex hormone-binding globulin leels were related to all-cause or cause-specific mortality. 3 Testosterone, a hormone that is present in high levels in males after puberty, is converted to dihydrotestosterone (DHT) by an enzyme called 5-alpha reductase. 4 This happens because of an excess of a chemical called dihydrotestosterone, or DHT, which causes the hair follicles to make thinner and thinner hair until they eventually pack up completely. 5 Further analysis showed that higher free testosterone and lower dihydrotestosterone levels were significantly associated with ischemic heart disease mortality. 6 Scientists have discovered that men with male pattern hair loss have an increased level of dihydrotestosterone (DHT) in their scalps . 7 Objective To observe the clinical therapeutic effect of Yifa compound treating female pattern hair loss and its effect on sera dihydrotestosterone(DHT) and dehydroepiandrosterone(DHEA) levels. 8 After treatment, the wet weight of prostate gland was detected,[www.] and the serum levels of testosterone (T) and dihydrotestosterone (DHT) were examined with radioimmunoassay method. 9 Prostate tumors and BPH are driven by the male hormone dihydrotestosterone, which is produced from testosterone by two forms of an enzyme called 5-alpha reductase. 10 This enzyme catalyzes one step in the conversion of testosterone to dihydrotestosterone, which is a hormone implicated in hair loss.
