by impotent i mean sterile, sorry if there was any confusion.
honestly, i wouldn't mind shrinkage lol.
Experiments with male rats seems to imply that the PM phytoestrogen does not cause sterility.
I'm taking 42mg/kg body weight per day, which most people consider a high dosage.
This paper says the following:
"The PM-10 and PM-100 treatments had no effect on testicular weight, sperm number, and serum LH, FSH, and testosterone levels. Only the PM-100 treatment reduced weights of epididymes and seminal vesicle and the sperm motility and viability." Where PM-10 and PM-100 means 10 or 100mg/kg body weight respectively.
The normal dosage for TG males is (according to Ainterol) 4 x 500mg per day. For someone of around 150 lbs, that equates to around 25mg/kg dosage.
The paper goes on to say:
" The present data clearly demonstrate that a long-term treatment of PM at doses 10 and 100 mg/kg BW/d, via oral route, does not alter a male fertility and a hypothalamus pituitary-testis axis. Although PM-100 can cause some moderate impairment, no persistent effects were observed. Most of PM-treated mice increased the mating efficiency after stop treatment."
Of course, we aren't rats (well, most of us).
All that being said, if having kids is important to you, it's probably worth getting your sperm frozen, just in case (and make sure the potential mother knows what's going on!
)
Good luck
