but we are restricted for example by pregnancy
Not all women are!!!!
What differences actually need to be mentioned? On average, women are shorter and not as strong as men. Does this need to be pointed out on a course? Other physical differences? Well, er, I find a four-point harness uncomfortable. Psychological differences? Sorry, that comes under the category of generalisation; that's why it's never covered in HPL.
The issue that everyone is skirting round is the dreaded period and PMT. But what to say? Well, if affects women differently and there are no generalisations. Honestly, there aren't. Some women can get grumpy, some don't. But hey! we've all had a grumpy male colleague; what's their excuse!!!!!
