The question of gender distinctions in English is a sensitive one. Extremism has added problems of its own. It is, linguistically, a new era and there are few reliable modern guidelines.   What is important is to use language that includes both men and women equally when writing or speaking English.

‘Man’ and ‘mankind’ have traditionally been used to mean human beings in general. Many people consider the use of these terms discriminates against women and such terms are now considered as old-fashioned or sexist. Modern writers prefer to use terms like ‘humankind’, ‘humanity’, ‘the human race’, ‘human beings’ or ‘people’. However, in some contexts there are no established alternatives, for example the verb ‘to master’ or, indeed, ‘a master’s degree’.

The –ess suffix in the names of occupation such as ‘waitress’, ‘actress’, ‘authoress’, and ‘hostess’ shows that the person doing the job is a woman. Many people now use the same word for both sexes because, in most cases, it is unnecessary to make a distinction between men and women doing the same job. The sex of the person doing the job should only be indicated if it is relevant to the context. ‘Waiter’, ‘actor’, ‘author’, ‘host’ are now used irrespective of sex. I have a personal dislike for newly-coined American terms such as waitron or waitperson, although the former, in particular, is gaining acceptance in South African English.

There is nothing wrong with using the appropriate male or female pronoun when referring to particular individuals.
When I asked my doctor, she said…’
It is also possible to use a neutral word like ‘assistant’, ‘worker’, ‘person’ or ‘officer’ instead of ‘–man’ or ‘–woman’ in the names of jobs, and many people prefer these alternatives.
‘Police officer’ is preferable to ‘policeman’ or ‘policewoman’.
‘Salesperson’ or ‘sales assistant’ is preferable to ‘salesman’ or ‘saleswoman’.
‘Head Teacher’ or ‘Principal’ is preferable to ‘headmaster’ or ‘headmistress’.
‘Chairperson’ or ‘chair’ is preferable to ‘chairman’ or ‘chairwoman’.
‘Firefighter is preferable to ‘fireman or firewoman’.

You might add these and similar unacceptable forms to your exclude dictionary in Microsoft Word.
‘Everybody’, ‘everyone’, ‘anybody’, ‘anyone’, ‘somebody’, and ‘someone’ are neutral terms and are usually followed by the plural pronouns ‘they’, ‘them’, ‘their’.
You can also use ‘he or she’, ‘his or hers’, ‘him or her’, especially in more formal speech or writing. 

Be aware that, despite this inclusivity, continued placing of one form before the other may also be considered as discriminatory. In writing, you can also use ‘he/she’ or ‘s/he’. I like the last option. Alternatively, the sentence can often be rephrased using a plural noun.
A doctor must treat his or her patients with respect.
