PixelFlux applications in reproductive medicine

Many papers have been published dealing with the evaluation of blood flow in male and female genital organs in animal and human medicine.

They agree on the usefulness of timing of ovulation by means of blood flow measurements of the ovaries. Many papers describe to correlation of the hormonal status and the perfusion of the reproductive organs.
