Aihio oli varmaan huono suomennos tästä. En muista mistä sen olen omaksunut, mutta tuossa selitetään se mitä tarkoitin:
"One of the first facts that all women should know is that all baby girls are born with all the eggs they will ever have in their lifetime. Unlike boys who do not start producing sperm until puberty, girls have all they will before birth. Over half of what you are born with will die off before puberty. While only one to two eggs are ever released in each cycle, a woman starts each cycle off with over 16 eggs in circulation. As she grows older this count will slow down and eventually she will run out of eggs and enter menopause.
It is a myth that a woman only uses one egg per cycle. She will start each cycle with up to 30 follicles. Each follicle contains an egg. Only one or two of the eggs will actually take over during a cycle and mature. Therefore, even though a girl baby can be born with as many as 450,000 eggs, she could only have less than 225,000 by the onset of puberty and will be using up to 30 of them each 25-40 days until she runs out. This means a normal woman will run out of eggs long before she runs out of years.
There is an actual biological pathway to how we are fertile. It actually begins with the brain, not our reproductive organs. There is a place of the brain called the hypothalamus. This place regulates many body functions like when we want to eat, drink, desire sleep, want to have sex, and other hormonal or endocrine functions. The role in releasing an egg begins with the release of FSH-RF – follicle stimulating hormone releasing factor. This hormone tells another part of the brain – the pituitary gland – to start releasing FSH –
follicle stimulating hormone. This starts the beginning of egg production. Many follicles that each contain one egg each, are stimulated from this chemical reaction."
