Here’s a short video of Lord Winston who, along with Dr Patrick Steptoe, pioneered in vitro fertilisation, telling some home truths about sex and gender.

As he said he can be expected to receive hate mail from the more deluded and aggressive members of the Cult of Trans but what he is saying is the absolute, unvarnished 100% truth. Humans cannot change sex. It might be possible for those with catastrophic mental illnesses such as Gender Dysphoria to create with drugs and surgery a simulacrum of the body that they desire, thereby reducing their mental distress, but changing sex is impossible to achieve completely as we are what we are on a molecular level. Whether your chromosomes are XX or XY is hard wired and impossible to change.
