Lectures on the Sūtra of the Collection of the Father and Son (Pitāputrasamāgamanasūtra) (22)

Beings in the form realm have no distinction of male and female forms

From the formless to the formed, all marks are false and illusory; if karmic seeds are dissolved, the marks are transformed. When we cultivate meditative concentration (dhyāna) and attain the dhyānas of the first, second, third, and fourth concentrations, then when our lives end and we are reborn in the form realm, that form body will have no distinction of male form or female form—at that time there will be no male and female marks. The fact that male and female forms can be transformed and changed shows that they are unreal, illusory, and false. Whatever can change is false; what is true never changes.
