Sex Hormone-Binding Globulin (SHBG) is a protein that binds to sex hormones, including testosterone and oestrogen and regulates their activity in the body. SHBG levels can influence the amount of active hormone available for use by tissues, which plays a role in fertility.

For women, low SHBG levels can be associated with conditions like polycystic ovary syndrome (PCOS) and can lead to an imbalance in hormones that may affect ovulation and fertility. High SHBG levels, on the other hand, can decrease the amount of free testosterone, potentially impacting ovulation and menstrual regularity.

Based on the results, your fertility specialists can guide you towards the best course of action to support your fertility journey.
