What Blood Tests Should I Get for Low Libido?
The top blood tests for low libido are free and total testosterone, TSH, estradiol, progesterone, and prolactin. Low testosterone is the leading hormonal cause of decreased sex drive in both sexes. Thyroid dysfunction and elevated prolactin also commonly suppress libido.
