I would like to conduct an experiment on medications that claim to enhance penis size. I mean no disrespect and am not trying to offend anyone, but this came about while my wife and I were watching the television. An infomercial for a male member enhancement pill called Azure came on and my wife and I were making jokes about it, but we also both wonder if products like that really work, they claim to add 1 to 3 inches of length. The design used would be the static group comparison. A control group and an experimental group will be assigned. No one will know until the end of the experiment who is in which group. .
The people selected will be men, between the ages of 18 to 65, with penis sizes of 3 to 6 inches erect (this is the size range the infomercial claimed they used), and they must not have any STD's or problems that hinder erection. They will be randomly assigned numbers which will determine what group they are in (computer generated numbers assigned to a 90 day supply of pills either placebo or Azure), which no one, including the technicians administering the medications or screening the applicants will know.
The dependant variable will be the size of the penis and if it increases. The independent variable will be the pills being administered. The treatment being applied is either a placebo made of sugar and fillers, and Azure an all natural, herbal pill that can supposedly increase the size of the penis by 1 to 3 inches. .
To insure internal validity I would do the following:.
1. Keep some things constant across all groups, such as health, penis size, number of subjects assigned to each group, etc. .
2. Include a control group using a placebo.
3. Randomly assign people to groups using computer generated numbers to assign subjects to placebo or Azure, without the experiment staff knowing which is which. .
The treatment would be a 90 day supply of Azure (or placebo), to be taken once daily until the pills are gone.
