Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
The sex hormone binding globulin (SHBG) test may be used to help evaluate men for low testosterone and women for excess testosterone production. It may be ordered in conjunction with other tests to evaluate the status of a person's sex hormones.SHBG is a protein that binds tightly to the hormones testosterone, dihydrotestosterone (DHT), and estradiol (an estrogen). In this bound state, SHBG transports these hormones in the blood as biologically inactive forms.HBG is ordered primarily when the total testosterone results do not seem to be consistent with clinical signs and symptoms, such as infertility, decreased sex drive, and erectile dysfunction in men or infertility, irregular menstrual periods, and excess facial and body hair in women.
A HSG (hysterosalpingogram) is commonly used to establish whether you tubes are clear-or not-by flushing a water-based dye through both tubes. This creates an X-ray image of the flow of the dye which shows the dye either spilling out the end of the tube, or being blocked and unable to pass through.hlamydia is often symptomless in women allowing the organism to cause blocked tubes before you even know that you have a hidden infection. An antibody test can show if you have had a prior infection with chlamydia. It is very common for tubes to be blocked in some way, shape or form.
