Scan the next ad (male)

Unsure whether testing headache medicine would be safe, I scanned the next ad. It said:

TYPE A SPERM DONORS NEEDED! Sperm typing will also be done.

Call 555-8310 for an appointment.

Didn't know sperms were also typed. I scanned further:

ARE YOU MAN ENOUGH? We will pay for your pain. MedLabz is in need of 30 volunteers for a pain tolerance experiment. Call 555-9201.

The more I'm not sure which ad to take. Maybe donating sperm would be easier. But wait, that's a donation, right? So, I won't get anything. Well, the choice now is getting pained or getting relief from pain.
