Job/career and reproductive success for males.

Previously just posted in alt.sci.sociology, uk.education.misc,

I am wondering about career choice/education and reproductive success
for males. This is really whether the man has any children, and the
number of children and partners. Education is really the degree
chosen.

I am interested in whether, for example software engineers have fewer
children than medical doctors, since they are less likely to meet a
partner at work.

Are physicists true to stereotype, and useless with women? (wrt
outcome).

What is the career with the best success, and is the variability, if
any, the career, or the underlying personality?

Since this is a sci.* newsgroup references to published studies are
appreciated (hopefully UK based, and I think there may be ethnic
variability.)
