Ovarian Reserve & AMH Testing

  
 

Ovarian reserves:

At puberty the human ovary have about 300,000 eggs of which few few hundreds are lost each month. Accordingly ovarian reserves are high at 20 years and low at 40 years
Ovarian reserves are an expression of the ability of the ovaries to make eggs which have the capacity to grow to amture eggs. it does not evaluate the quality of these eggs.
Ovarian reserves can be measured by vaginal ultrasound by counting the number of follicle (which carry the microscopic egg) and relating it to the number of folicles expected to be seen at that age. The findings of 9-10 follicle on each ovary is an indication of very good reserves while 0-2 suggest Low reserves.
AntiMullerian hormone AMH is secreted by the small grownig follicles before they are seen by ultrasound, can be done anytime of the cycle and is more accurate in assessng ovarian reserves than FSH and LH. AMH level of > 20 indicate good reserves while levels < 3 indicate very low reserves.
A high ovarian reserves suggest good fertility potentials while low reserves is associated with low potentials.
