HUMAN REPRODUCTION Male and female reproductive organs Eggs or ovules are stored in the ovaries At birth, there are approximately 1 million to 2 million eggs; by the time of puberty, only about 300,000 remain. Of these, only about 500 will be ovulated during a woman's reproductive lifetime. Any remaining eggs gradually die out at menopause the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
