However, not all sperm are positively impacted; some appear to remain uninfluenced and some actually move away from the egg. All sex chromosomes started out as an original autosome of an original amniote that relied upon temperature to determine the sex of offspring. The time at which insemination occurs during the oestrus cycle has been found to affect the sex ratio of the offspring of humans, cattle, hamsters, and other mammals. This perspective still shares the classical way of thinking; that in order to produce two sexes, nature has developed a default female pathway and an active pathway by which male genes would initiate the process of determining a male sex, as something that is developed in addition to and based on the default female form. The first clues to the existence of a factor that determines the development of testis in mammals came from experiments carried out by , who castrated embryonic rabbits in utero and noticed that they all developed as female.

The idea is instead of having a simplistic mechanism by which you have pro-male genes going all the way to make a male, in fact there is a solid balance between pro-male genes and anti-male genes and if there is a little too much of anti-male genes, there may be a female born and if there is a little too much of pro-male genes then there will be a male born. .
