Overview
When a couple is trying to conceive, understanding the body’s hormonal balance is an important step. Hormones guide many reproductive processes, including ovulation, egg development, and the preparation of the uterus for pregnancy.
One of the key hormones involved in female fertility is Estradiol (E2).
The Estradiol Test is a simple blood test used in fertility evaluation to measure the level of estradiol, a form of estrogen, in the body.
This hormone plays a crucial role in ovarian function, egg development, menstrual cycle regulation, and overall reproductive health.
At Milann Fertility & Birthing Hospital, the Estradiol blood test is often recommended as part of a comprehensive fertility assessment.
It helps doctors understand how the ovaries are functioning and whether the body is preparing normally for ovulation and pregnancy.
