Document Summary
Sexual reproduction always includes meiosis and fertilization, requiring the generation of sperm and egg. Sperm and egg production under hormonal control (along with temperature and circadian rhythm). In animals with brains, the best way to assure reproduction when animals are most likely to produce offspring is to link sexual behavior with pleasure. It is largely experientially determined and culturally sanctioned. Hormones are often necessary but almost never sufficient but of course, not always! There are as many sexual preferences as there are people. One major result of sex research is that we have sex because it feels good, not because we want to make babies. Sex: associated with a division of gamete types. Sexual behaviour: behaviour that has evolved to bring the two gamete types together. Male sexual behaviour: all behaviours necessary & sufficient to deliver male gametes (sperm) to female gamete (ovum)
