UK researchers develop way of predicting a woman's 'reproductive' age
UK researchers have shown a strong direct relationship between ovarian volume and the number of primordial follicles (eggs) remaining in the ovaries of women of reproductive age. The measurement of ovarian volume by transvaginal ultrasound will enable an accurate prediction of the age of menopause and hence a woman's reproductive age. They say... view more... (2004-06-15)
