Antonio Forgiarini, gynaecologist at Next Fertility Valencia, tells us in this video whether oocyte quality is the same as oocyte quantity:
No. It's not exactly the same. In most of cases, quality and quantity goes in a parallel way. So, normally, they're related to the age of the woman. All women start, from the adolescence to the menopause, with a certain number of oocytes and they are losing them during the years. And the quality of the oocytes is also going worse during the years. But there's some cases like an early menopause, for example, where we have young women with good quality of oocytes, but a very low quantity, so they've few oocytes but of a good quality. And on the other side, for example, polycystic women, they can have 40-41 years so, normally, we expect low quantity but, for their condition, they have a lot of oocytes. But these oocytes are of bad quality. So, in this cases, they're not the same. So we need more oocytes to have a good pregnancy.
