Worried about infertility as a Marine Engineer

Okay so this is really random, and I appreciate that it's extremely niche, but it's a real fear I have and would like some perspective from those who know what it's like to work in the engine room.

I'm a woman (20 yo) and am studying marine engineering with naval architecture. I want to pursue a career on board a vessel as an engineer in the engine room/on watch.

I'm currently on a placement year in a shipyard, overseeing the construction of a cruise ship that I may potentially work onboard in the future. Today someone mentioned that the coating business is not the best place health-wise for a lady to go into - stating that after work he is not supposed to go near his children or his wife if she's pregnant, due to chemicals that may be on him or fumes etc.

That got me thinking about the conditions in the engine room, and if they might pose the same risks. I know I want to have children in the future, preferably my own-birthed children (but not against adopting or other methods), so I'm just wondering if anyone has any experience or knowledge about the health implications from working in the engine room.

I'm expecting that I'll start my career on watch in the engine room for long hours of the day - are the fumes or air I'll encounter particularly damaging to my health as a woman? Of course I know that fumes and all that are unavoidable as part of the job, but if there's any specific risks to my reproductive system I'd like to be informed - if anyone has any information or experiences please do share. Not sure if I'm being paranoid or this is a reasonable concern.
