A lot of this medical talk is like reading greek to me, but I do understand some of it.
"But... doesn't testosterone grow bones?"
Testosterone is synthesized into estrogen which does effect your bones, from a certain perspective you could say that testosterone does grow bones:

Nowadays, it is well-recognized that estrogen is important in bone homeostasis playing a pivotal role in longitudinal bone growth in both male and female skeletons. In females, during the early stages of puberty, low levels of estrogen allow for the rapid growth of the bone, and towards the end of puberty high levels of estrogen result in the closure of the growth plate [11]. In males, it was previously thought that androgen was responsible for skeletal growth. This hypothesis changed after the reports and careful analysis of two anomalies in the male skeleton involving estrogen synthesis and signaling pathway. The first one was the clinical report of a male patient exhibiting bone growth even into adulthood. This patient carried a mutation in codon 157 in both alleles of the estrogen receptor alpha (ERα) changing a cytosine for thymine resulting in a premature stop codon. This mutation resulted in tall stature due to the lack of growth plate fusion. Despite the abnormal length of the bone and high levels of testosterone, he had low bone density (3.1 SD below the mean for age-matched normal women), resulting in osteoporosis [12]. The second finding was the identification of two male patients with similar clinical characteristics as previously described patients, but in their cases, an aromatase p450 deficiency was responsible for the same clinical outcome [13,14].

A total of 52 randomized controlled trials (RCTs) were included. When compared with placebo, testosterone supplementation did not increase total BMD (short-term: 1081 participants, MD − 0.01 g/cm2, 95% CI − 0.02 g/cm2 to 0.01 g/cm2; long-term: 156 participants, MD 0.04 g/cm2, 95% CI − 0.07 g/cm2 to 0.14 g/cm2), lumbar spine, hip, or femur neck BMD. Furthermore, testosterone supplementation did not decrease the risk of falling or fracture. Lastly, it was found that testosterone supplementation did not increase the risk of cardiovascular events (1374 participants, RR 1.28, 95% CI 0.62 to 2.64), all-cause mortality (729 participants, RR 0.55, 95% CI 0.29 to 1.04), or prostatic events. However, testosterone supplementation may improve sexual function and quality of life (1328 participants, MD -1.32, 95% CI − 2.11 to − 0.52).
