PCT Question. Why nolva/chlomid?

[WannaBeBig72]

I finished my first cycle a couple of months ago. My PCT consisted of only HCG (10,000 ius - 10 injections EOD). I started 5 days after last injection. I was able to keep all of my strength gains (lost some water wait probably). I went to my doctor before cycle and right before PCT and he told me I didn't need any nolva/chlomid, that the HCG is all that I need. My doctor is kind of a juicehead himself.

Anyway...Why do alot of people take chlomid or nolva for PCT? I mean they're both anti-estrogens? I don't see how either would help your nuts come back...
