Good afternoon! Low testosterone levels in young men are most often the result of endocrine disorders or genetic syndromes. Before any treatment can be undertaken, a diagnosis must be made. We recommend that you donate blood for the hormones FSH, LH, testosterone, SHBG, prolactin, TSH (tests No. 56, 59, 60, 61, 64, 149 in the INVITRO Laboratory), donate blood for the karyotype (test No. 7811), perform ultrasound of the scrotum and contact an andrologist or urologist
Yes, the voice may become lower, the hairline of the face may increase. But I don't quite understand how a person can become sick with masculinity, as far as I know, masculinity is a behavioral and mental characteristic. If you meant the so-called "masculine features", for example, pronounced brow ridges, a large chin, then these are all congenital facial features, and testosterone cannot change them.
