There is no gender distinction in independent personal pronouns, not even in 3SG ((a)el) or in 3PL ((a)es). Only the singular personal pronouns expressing politeness have a gender distinction both as tonic (independent) pronouns, e.g. (a)nho (M)/(a)nha (F), and as atonic (proclitic) subject pronouns, e.g. nhu (M)/nha (F). (The - always optional - a- in ael, aes, anho, anha etc. indicates that the tonic pronoun is the topic of the sentence.)
