Sharron Davies MBE revealed she has been threatened over her views on transgender women competing in women's sport.
Swimmer Lia Thomas sparked huge debate around the subject when she became the first transgender woman to win an NCAA swimming title.
Debate raged around whether Lia should be able to compete in the women's division after transitioning from a male.
Labour MP Charlotte Nichols congratulated Lia on her achievement, branding any criticism as "lazy transphobia".
But Olympic silver medallist Ms Davies argued that it was unfair for women for Lia to be competing against them.

Since airing her views, Ms Davies revealed on Twitter she had received "several threats".
She wrote: "I’ve received several threats to myself and my work because I present evidence based facts on the unfairness of male inclusion in women’s sport.
"Which is biological sex based decriminalisation. I will not stop bringing these actual facts into the light or be bullied into silence.
"I’m used to it now. But I feel we are turning the corner and open debate to find science based solutions are not far away that will protect the integrity and rights of females in sport as well as offering up ways to be inclusive but not as the cost of another groups rights."

Thomas' victory came after a civil rights complaint was submitted against the University of Pennsylvania for permitting her to compete on its swimming team.
Also brought up was Lia's ranking of 462nd when she competed in the male ranks.
Rival Reka Gyorgy complained to the athletics association about its decision to let Lia race against "biological women".
But Labour equalities minister ms Nichols firmly sided with Lia competing in women's sport.
She wrote: "As a former competitive swimmer myself, indeed, I know full well how much training is required for a title like this.
"Anyone trying to diminish Lia Thomas' achievement because of lazy transphobia should frankly pipe down.
"Huge congratulations to her."
