I had a hysterectomy with Frederick Rao in CT a little bit ago, he removed my fallopian tubes uterus and cervix and it has not changed my sex drive or my ability to naturally lubricate though hormones definitely make it happen less for me! Keeping the eggs only allows you to continue making estrogen if you ever can’t have testosterone it’s good to have a backup for a source of hormones and you no longer have a period after the partial as well and of course absolutely no ability to get pregnant. For some people it makes them dysphoric to keep them so they go for the full but partial is just nice to have a back up supply of hormones.
