Melissa Green, chief executive of the National Federation of Women's Institutes, said: "Unfortunately the legal position as it stands means that we can no longer offer that."
The decision comes after "40 years of fellowship and sisterhood with those women", she told BBC Radio 4's Woman's Hour.
The Women's Institute describes itself as "a legally recognised women's organisation and charity", and to comply with the Supreme Court judgement says it must "restrict formal membership to biological women only".
The organization said it would create a new national network of "sisterhood groups" alongside Women's Institutes that want to offer a "trans-inclusive space" to "develop that friendship and support for transgender women".
