Catatan
Male fertility parameters are declining globally. The Y chromosome is shortening
over generations and may eventually disappear in course of evolution. Colleagues
have shown a higher proportion of X chromosome-bearing sperm in the semen and
have suggested that there is a preferential elimination of Y chromosome-bearing
sperm during their passage through the male genital tract. However, male embryos
are better protected in womb. At birth, for 100 females 106 males are born. Males in
each age group are more prone to morbidity and mortality, and at the end, elderly
females outnumber men in most parts of the world. Males retain their fertility till the
ripe old age, whereas females lose theirs in the middle phase of life. Males are bio-
logically driven to be aggressive and polygamous probably to amplify gene diver-
sity. Male sexuality and reproduction have always remained an enigma.
