I am 28yr married male. I got married 1.5 yrs back. Suddenly, since six months some times I feel, I am not getting proper erection. When I dont get that thought I perform normally. I visited a urologist and got diagnosed to low testosterone.

Free testosterone. 0.178 nmol/L Normal Males : 0.204 - 0.637
SHGB(method ECLIA) 33.67 nmol/L Normal Males : 14.5 -48.4
Free testosterone Index 22.36 % Normal Males : 33.5 -106
Bio-Available testosterone 4.17 nmol/L Normal Males : 4.78 - 14.9
Total testosterone(method ECLIA) 2.17 ng/ml Adult male : 2.8 - 8.0

Doctor Suggested the following medicines :
1) Inj Sustanon 250mg(Im Deep)
2)Tab Penegra 50mg - 5
3) Tab nano Leo -10
4)Tab Ignitor -10

I was injected Sustenon the same day. But I was scared and doubtful of using those tablets. hence I did not use them till now.

But after I was injected sustanon I felt I am having normal sex life.When ever I remember those days or when I overthink about It during sex, I get scared and loose the erection.

Now I am planning to have baby. and I am frequently getting those thoughts and hence not able to participate in sex. Please suggest me, Can I start using those tablets mentioned above. Will they have any affects on fertility and natural sperm functionality process. If not please suggest me an alternative medication.

Please reply to my email, as I have immense faith in your suggestions rather than any other regular doctors.
