Using Exogenous FSH Ovarian Reserve Test and Ultrasound in the IVF clinic Ovarian reserve is the term used to describe the number of good quality eggs left within a woman’s ovaries. A woman is born with approximately 1,5 million eggs and over her reproductive life her egg numbers will decline as they are lost through natural attrition and ovulation. Only approximately 400 eggs are lost through the process of ovulation. The remaining eggs are lost through natural cell death (apoptosis).Women with family history of early menopause, a history of surgery to the ovary or severe pathology, are all at increased risk of early diminished ovarian reserve. The only way to identify this population is with the use of ovarian reserve testing- EFORT (Exogenous FSH Ovarian Reserve Test).

Termenul de rezervă ovariană a aparut ca necesitate de a defini cantitatea de foliculi şi calitatea ovocitelor din ele, şi evaluarea funcţiei reproductive nu numai dupa vârsta pacientei dar dupa posibiliatatea ei reala de a concepe o sarcina. Rezerva ovariana constituie mărimea şi numărul total de foliculi ovarieni cu ovocitele din ele ce se gasesc in ambele ovare. Sau altfel fel spus este numărul de ovocite la femeie într-un momentul dat care pot fi utilizate în fertilizare. Odata cu înaintarea în vârsta a femeii are loc declinul funcţiei reproductive, manifestindu-se şi prin scăderea rezevei ovariene.
