How Fertility Tests Work

The FIRST RESPONSE Female Fertility Test PLUS Pregnancy Test Stick is an effective screening tool to evaluate one of the leading single factor causes of infertility, diminished ovarian reserve (egg quantity and quality). Fertility tests measure levels of Follicle Stimulating Hormone (FSH) to gauge your ovarian reserve, and your chances of becoming pregnant.

Every woman is born with millions of immature eggs. Over the course of her life the quantity and the quality of her eggs — known as her ovarian reserve — decreases.

Follicle Stimulating Hormone (FSH) is released at the beginning of every menstrual cycle to cause an egg to mature in the ovary. If a woman’s ovarian reserve (eggs) is low, she will produce higher than normal FSH levels to attempt to stimulate her ovary to produce mature eggs.

Testing FSH levels on Day 3 of the menstrual cycle gauges a woman’s pregnancy potential. The FIRST RESPONSE Female Fertility Test PLUS Pregnancy Test Stick is an early detection screening tool that assesses Day 3 FSH levels to begin answering the question "Am I able to get pregnant?"

Early detection of FSH levels — and by extension Ovarian reserve levels — empowers women to know sooner, consult with a physician sooner and ultimately get pregnant sooner.
