“My family doctor basically told me that I had to live with my Low T problem which was not something I wanted to hear. He told me this for 2 years and in fact it made me so mad that I am no longer his patient. I decided to get checked at TCT. After a thorough evaluation, including checking my blood, they told me that Low T was not something that I had to live with and in fact, they have helped with my other medical problems. They are treating my blood pressure, cholesterol and erection problems as well. I’m in my late forties and finally feel like I have been “tuned-up”. I feel better than I have in years which allows me to focus less on me and more on the things I find important. Thank you to everyone who helped get me where I am, including my ex-doctor. Keep up the good work TCT!” — Todd J.
Other significant adverse effects of testosterone supplementation include acceleration of pre-existing prostate cancer growth in individuals who have undergone androgen deprivation; increased hematocrit , which can require venipuncture in order to treat; and, exacerbation of sleep apnea .  Adverse effects may also include minor side-effects such as acne and oily skin, as well as, significant hair loss and/or thinning of the hair, which may be prevented with 5-alpha reductase inhibitors ordinarily used for the treatment of benign prostatic hyperplasia , such as finasteride .  Exogenous testosterone may also cause suppression of spermatogenesis , leading to, in some cases, infertility.  It is recommended that physicians screen for prostate cancer with a digital rectal exam and prostate-specific antigen (PSA) level before starting therapy, and monitor PSA and hematocrit levels closely during therapy.
