I have to disagree with Ivana. You can say zdravotni bratr but it's not as widely used given to the high number or female nurses in comparison to male.

Thank you! Kristýna and Ivana Ne!

you cannot say zdravotní bratr only zdravotní sestra (woman). For man you can use zdravotník, (for woman zdravotnice

Hi! Do you mean words used only for male/female as in jobs? Yes, you can say zdravotní bratr, it means male nurse and you can't use it for a female nurse. This is probably one of rare cases where the word for male/female worker is completely different, because it uses the words brother/sister (bratr/sestra). Usually, we only add a different ending to the male version or the words have the same root at least. Examples of some male/female words for jobs: Kuchař/kuchařka - a Cook Číšník/číšnice - a waiter/waitress Soudce/soudkyně - a judge Lékař/lékařka - a doctor Herec/herečka - an actor/actress Překladatel/překladatelka - a translator Spisovatel/spisovatelka - a writer Policista/policistka - a cop Učitel/učitelka - a teacher Prodavač/prodavačka - a shop assistant This usually applies to other gendered words, not just jobs, for example: Útočník/útočnice - an attacker Student/studentka - a student Zloděj/zlodějka - a Thief Hope it helped a bit. If this isn't what you were asking for or you want more examples, you can send me a message and I will gladly help you :)
