What is the Hormone that is Detected in an In-Home Fertility Test?

The hormone that is detected by fertility tests is the follicle stimulating hormone, which tests the ovarian reserve, notes Dr. Kecia Gaither, Director of Maternal Fetal Medicine in the Department of Obstetrics and Gynecology at Brookdale University Hospital in Brooklyn, New York. “This basically provides a read on how well the ovaries are functioning and how likely they are to produce good eggs,” says Gaither. For best results, blood or urine tests for FSH should be conducted on day two or three of your menstrual cycle.
