What are the teachings of Catholic Church on the implications of gender-change by individuals, in their life-after-life? We read at Gen 5:1-2:
&quot;&quot;... When God created humankind, he made them in the likeness of God.  Male and female he created them, and he blessed them and named them “Humankind” when they were created. &quot;
That implies that each human being continues to belong to his/her  gender in the life-after-life. Now, there are some who opt to change their gender for various reasons, former wrestler Gabbi Tuft being the latest edition to the list. To what gender do such individuals belong to, in the life to come  is a matter of curiosity for all. Will they retain the gender in which they had been born , or will they change over to the newly assumed gender , in the life to come ? My  question therefore,  is: What are the teachings of Catholic Church on the implications of gender-change by individuals, in their life-after-life ?
&quot;Sex-change operations&quot; are mutilations of the body, changes in the accidents (not substance) of a human.(The soul doesn't have a sex; St. Ambrose On Virginity ch. 15: &quot;anima enim sexum non habet&quot;, &quot;for the soul doesn't have a sex&quot;.)

Only scars of wounds, not lost limbs or major mutilations, can remain in resurrected bodies, as St. Thomas writes in Summa Theologica suppl. q. 82 a. 1 ad 5:The scars of wounds will not be in the saints, nor were they in Christ, in so far as they imply a defect, but as signs of the most steadfast virtue whereby the saints suffered for the sake of justice and faith: so that this will increase their own and others' joy (cf. q. 54 a. 4 ad 3). Hence Augustine says (De Civ. Dei xxii, 19):We feel an undescribable love for the blessed martyrs so as to desire to see in that kingdom the scars of the wounds in their bodies, which they bore for Christ's name. Perchance indeed we shall see them for this will not make them less comely but more glorious. A certain beauty will shine in them, a beauty though in the body, yet not of the body but of virtue.Nevertheless those martyrs who have been maimed and deprived of their limbs will not be without those limbs in the resurrection of the dead, for to them it is said (Lk. 21:18): &quot;A hair of your head shall not perish.&quot;

∴, the sex of humans with their resurrected bodies will be that in which God created them.
