Natesto
Active Comparator group
Description:
Natesto™ is a testosterone nasal gel that is FDA approved to treat low testosterone. It delivers testosterone through the nasal passages and it is then absorbed into the blood stream. The nasal pump is placed at the opening of each nostril and then the participant would press down on the nasal pump to apply the gel. Each application takes about 10 seconds and the nasal pump applies a thin layer of gel that absorbs through the lining of the nose.
Treatment:
Drug: Natesto Nasal Product
Placebo
Placebo Comparator group
Description:
This study involves a placebo. The placebo will look like the Natesto™ nasal pump and will contain a nasal gel, but without any active ingredients.
Treatment:
Drug: Placebo
