I love the eunuch calm post orchie that I get on just estrogen ( my T levels was down to 14) but am worried about muscle loss so my gynecologist had me doing 1 pump ever other day and it raised my T to over 200! I only get my blood checked every 3 months. I quickly stopped because …I was getting those undesired erections, inceased hair growth and slighly edgy. (The damn make aggression from T!). Got my T down to nothing again and now I am on about a 1/4 pump ever day….so far I feel fine….havent had my blood work checked …1 more month. This is a balancing act and many trade offs. But bottom line, I wish I had seen a urologist 30 years ago and gone down this path much sooner. I love the feeling

I was prescribed testogel, 50mg. / have been lowdosing my t since I was castrated - completely off T was not my cup of Thea, I had to endure being completely hormone free for 4 weeks and it was really hard to function.
Lowdosing T meant virtually no libido, nocturnal erections if they occurred, were weak and short lived.
Spontaneous erections during the day have been completely absent since my castration even when I was on full dose T for a couple of months afterwards,

As I haven’t discussed the adjustment of lowdosing T with my endocrinologist I have had to remain stealth and I always took full dose of testogel prior to bloodtest.

However latest bloodtest despite I took full dose testogel a couple of hours before having my blood drawn, my levels were only 9.7nmol for testosterone and free T 0.22nmol.

I think the shrinkage is not because you are a Eunuch. But more because of the lack of T. I go to the Young Men's Christian Association (YMCA) here in America and all the older men have small penis. They are all small, I have concluded. Before my castration, I told my Urologist that I must have the smallest penis ever. And his reply was, "Mine is even smaller than yours. Don't feel bad." As a teenager in school, I used to be so ashamed because my penis was so small in the shower room. Penis small is the story of my whole life.
