Infertility/Fertility/High estrogene


Hello,  my estrogen levels vary from 116 to 243 over the cycle monitoring I have done over the past few months.  Is estrogen levels higher than 200 considered too high? Could this cause my infertility?

Hello Andrea from Canada (again),

No for both your questions. Estrogen levels will vary depending on the part of the cycle where it is tested.  For that reason, estradiol is usully only measured on the second or third day of menses for proper interpretation.  Estrogen levels at the time of ovulation can be high dependent on the number of follicles that have been stimulated (such as during an ovulation induction cycle or IVF cycle).

Good Luck,
