Everyone with baseline low T has a slight increase in PSA when starting TRT. It's part of the saturation point.I am not sure if I had sex before it. I think I did. Do people usually have an increase in psa value as they use trt or psa stabilize after some time ?
Time-course of effects on the prostateIn hypogonadal men treated with testosterone, levels of PSA rise usually up to levels of eugonadal men (84). Upon judging the time-course of effects of testosterone on the prostate, it is of note that aging itself is a factor in the rise of both prostate volume and PSA (84), and there is no endpoint in the effects of testosterone on the prostate. A rise in PSA levels was noticed after 6 months, whereafter over the following 24 months there was no significant further increase (85). Other studies have found a rise of PSA levels after 3 months (40), some only after 12 months (43). An increase in prostate volume was noted after 3 months (86) and after 12 months (44). One study over 24 months found no significant increase in both PSA and prostate volume. In a study of 123 subjects over 42 months of testosterone gel application, there was significant increase in serum PSA over the first 6 months and then no further significant increases with continued testosterone treatment was found (87). In a study of 81 hypogonadal men (mean age 56.8 years) followed for a mean (range) of 33.8 (6–144) months PSA levels did not increase significantly at 1-year intervals for 5 years (88). The data are summarized in Fig. 5.
