I am 28 years old man and I used to get very Healthy erections by age of 25. But That was a time when I started to wear very tight underarment/supporter in Gym due to wrong advice. now I neither get morning erections nor while masturbating. I am very normal health , No BP/Sugar, no smoking/alcohol, do regular exercise . My blood test reports 17 OH PROGESTERONE 1.39 ng/mL ,ANDROSTENEDIONE (A4) 1.77 ng/ml, DHEA - SULPHATE (DHEAS) 377.2 µg/dl , FREE TESTOSTERONE 5.96 pg/ml , FSH 1.68 , LH 5.5 ,Prolatin 23.09, SHBG 31.35 , Testosterone 280 (range 241-827), T3 93 ,T4 5.2 ,TSH 0.43, Vit B12 159 (Range 211- 911),FREE TESTOSTERONE E.L.I.S.A 27.3 pg/ml (Insufficiency) , HB -16.8 Kindly Guide. (Tadafil 10 mg gave me firm erection but at this age I wish to solve problem from root. Consuming 3-4 garlic cloves before sleep has given me mild (30% ) erection both at morning and while masturbating. Though both quality and quantity of semen after ejalucation is low)
