What estrogen level indicates infertility, based on the provided patient record?

The identification of estrogen levels that suggest infertility is a nuanced aspect of reproductive health. A level of 25 pg/mL is considered to be on the lower end of the normal range for estrogen production, especially during the luteal phase of the menstrual cycle, which is crucial for preparing the uterus for a potential pregnancy. Estrogen plays a vital role in regulating various reproductive functions, including the thickening of the uterine lining (endometrium) necessary for implantation.

When estrogen levels fall below a particular threshold, as indicated by 25 pg/mL, it can result in insufficient endometrial development, making it more challenging for implantation to occur and thus increasing the risk of infertility. This understanding is essential for evaluating reproductive health and guiding further diagnostic assessments or treatments.

Estrogen levels higher than 25 pg/mL, such as 30 pg/mL, 40 pg/mL, or even 15 pg/mL may still permit some level of reproductive function or could be within a range that doesn't necessarily indicate infertility. Each of these values may require further context, such as the specific timing of menstrual cycles or additional hormonal assessments, to provide a complete picture. Therefore, establishing a level of 25 pg/mL as indicative of potential
