The presence/absence of sperm in ejaculate - in and of itself - has no bearing on sexual performance. That said, most men on TRT notice a reduction in ejaculate volume.
Orgasms are as good, libido is way higher, volume is a bit lower but I now i do it every day so lower volume may be ralated to higher sex frequency for me. I do use HCG though so this probably helps.
We definitely are all different. I make a lot less semen now. But my libido and sexual orgasm are probably too strong. I am very fortunate to have a woman that wants them traits in a man.
