The male subjects will pay for their own testosterone tests. Saliva tests cost about $60.
We'll recruit female subjects via Facebook ads (18-30 years old, not pregnant, not on oral contraceptives). They'll be paid $25 each. The women will wear scrunchies in their hair during the week before ovulation (tracked via free fertility apps). The women will mail their scrunchies to us in ziplock bags.
We'll vacuum seal the ziplock bags and mail these to the male subjects.
The men will dampen the scrunchies then wipe them on their upper lips.
Half of the men will receive new scrunchies (controls). The men will be divided into three groups receiving 15, 8, or 4 scrunchies per month.
We need a minimum of 24 men and about 120 women. To save money we'll cut scrunchies in half, or have women wear two scrunchies, or have women wear gauze pads under their arms.
For each female $10 advertising, $25 payment, $10 for the scrunchie and postage; subtotal $45. With 120 women the total is $5400 for one scrunchie per woman per month. Our minimum budget is $1350, in which each woman sends us four items (two scrunchies and two gauze pads, two scrunchies cut in half, etc.).
We'll recruit the male subjects from the men who donate to this project who are not on hormone replacement therapy, are at least 18 years old, and are in the United States.
For 24 men we need 216 mailings. We're budgeting $10 per mailing for packaging, postage, mailing labels, etc. We could save money by mailing First Class or by including several scrunchies in one package. This totals $2160 for the male subjects. Our minimum budget is $5 per mailing, with 2 items per mailing, or $540 total.
We should be able to accept male subjects for a $100 donation. If we exceed our funding goals via larger donations ($350 or more) we'll use more scrunchies and fewer gauze pads, etc. If we exceed our funding goals via many small donations ($100 or less) we'll add more subjects but stay with the "low-budget" plan.
