Being a woman and a biologist, that is to say, having studied the life sciences, I am still surprised by how little I know about the biological changes that being a woman entails. Conversing with friends, we comment that no one ever explained to us what menopause really involved, as well as the associated bodily, organic, and metabolic changes. Regarding menstruation, although it may seem that it is now liberated and that everyone talks about it freely, it is also not explained what it really means for a girl's body, nor the transient and permanent changes that this biological stage implies. Dysfunctions such as endometriosis are now starting to be diagnosed and studied; regarding the effect of contraceptive hormones on our body, they have only been mentioned to us for their contraceptive effect, but not for the extent of the unnatural hormonal treatment that it represents when taken prolonged over years; nor has anyone spoken to us about the loss of ovarian reserve with age, a matter that is now increasingly present because women want to be mothers at more advanced ages. It almost seems as if women were invisible.
