Hi, I am now 31 years old, and I am a doctor. I would like to know from a specialist if I have Testosterone deficiency. I had a late puberty (older than 15 years old). I still have sparse facial and body hair (I have no beard). I have mild gynecomastia. I am not obese, but rather slim. Weight and height are within normal limits. Libido is low. I suffer from (at least) moderate depression. I have significant forgetfulness and difficulty finding words. Energy is low. Penis and testicles are normal in size. I tested my Testosterone before and the level was 22 ng/ml (normal range in that lab was 10-58 in men). This Testosterone level was almost three years ago (when I was 28) and it was the highest amonth other two (the rest I believe were about 18). I also tested my prolactin which was normal. I would like to know if this level is low for my age, and if I have relative Testosterone deficiency. I also would like to ask about GnRH treatment in this case (i do not prefer taking external testosterone).
