I had THR on left his Jan. 3, 2017. I was released the 5th to go home feeling great and doing well with Walker. I felt good. With very little pain until first home PT session on the 11th. The girl did evaluation and pushed and pulled some. I napped afterward and woke up hurting. The pain was not as severe as before surgery but definitely more than I had been having. The PT person didn’t show up Friday as scheduled. I went to my doctor and got staples removed the 17th and he said pain probably from pulled muscle. I am changing to out patient therapy. But I would tell anyone looking into THR not to wait. I wish I had it months before I did. I put it off until after the holidays and if I had known how much less I would hurt I would never have waited.
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. 
If you test out as deficient in testosterone, or if you have symptoms of low testosterone, you likely want to do something about it. There are definitely over-the-counter supplements designed for this very purpose. ( Alpha Male® and Tribex® are the most potent.) And while effective, they're best used by healthy younger men who want a boost in T levels for bodybuilding purposes. They probably aren't the best choice for men who are clinically low and who've made the choice to undergo what's usually a lifetime commitment to testosterone replacement therapy, or TRT.
