<human>: I started at this company about a month and a half ago and learned during the interview there was only one other woman at this branch of the company.The other branch has about 6 woman in an office of about 60 people.

This week the only other woman at my branch gave her notice. This means starting next week, I will be the youngest and only female at this branch. 

This other woman shared some words with me and concerns with me as to how some of the men have spoken to her while working and she responds with something like "save it for happy
hour." While no one here has said anything to that effect to me, I have over head some conversations where employees here were referring to customers of ours that are woman in a derogatory manner.

My concern is that once this other woman leaves I will be left to tolerate all this testosterone on my own.

Can you summarize the given text in a few sentences?
<bot>: Youngest in office and only female. Concerned about unbalanced hormones in the office and how to combat them in a professional manner
