Non-Linear Association of Serum Sex Hormone Binding Globulin Concentration with Female Infertility.

Background: Accumulating proofs suggested that disturbance of serum sex hormone-binding globulin (SHBG) concentration can affect the reproductive system. However, the effect of serum SHBG on female infertility remains to be clarified.

Methods: Data from 1,787 adults from the National Health and Nutrition Examination Survey (NHANES) was applied to examine the correlation between serum SHBG and female infertility.

Elevated HbA1c Level has a Linear Association with Infertility in Women.

Background: Hemoglobin A1c (HbA1c) is commonly known as a plasma glucose monitoring indicator. However, the relationship between HbA1c and fertility has not been clarified in previous literature. This study aims to investigate the association between HbA1c and the incidence of infertility.
