How does castration affect the male body?

Testosterone is produced by cells in testicles in response to leutenizing hormone. LH is produced by the anterior pituitary gland. It's feedback loop works as such that low levels of testosterone results in an increase of LH, which in turn causes cells to secrete more testosterone. The testosterone then signals to the pituitary to decrease LH production; this ensures that testosterone isn't over produced. When one experiences castration, their feedback loop gets messed up. Without testosterone, LH production goes into overdrive, but there is no increase in testosterone.
Some side effects of little/no testosterone:
decreased libido
Increased gynecomastia (breast tissue production)
decreased spermatogenesis
A few other consequences include:
infertility
possible body hair decrease
possible body strength and muscle mass decrease
Furthermore, testosterone is converted into DHT; a hormone responsible for external male sex organ differentiation, and for male pattern baldness. If testosterone production, and therefore DHT production is decreased, then males can prevent their male pattern baldness.
Another problem that arrises, is caused by the hormone replacement therapy. The steroids inhibits production of LH, which therefore decreases testosterone production. This is what causes male's [who take steroids] testicles to shrink. It can also cause breast enlargement.
However, if one chooses not to have hormone replacement therapy, they will most likely experience some of the following side effects:
hot flashes
gradual bone-density loss, which causes osteopenia or osteoporosis
potential weight gain or redistribution of body fat to
