The effect of doxycycline hyclate on human fertility is not known.
Fertility studies on animals have shown complications.

"... Pregnancy/Reproduction
Adverse effects on fertility and reproductive performance were observed in both male and female Sprague-Dawley rats given oral doxycyline hyclate. {01} These effects included increased time required for mating to occur, reduced sperm motility, velocity, and concentration, abnormal sperm morphology, and increased preimplantation and postimplantation losses. {01} A range of doses of doxycycline hyclate was studied; the lowest dose tested was 50 milligrams per kilogram of body weight per day (mg/kg/day). {01} All doses studied resulted in reproductive toxicity, including the lowest dose, which resulted in a significant reduction in sperm velocity. {01} The 50 mg/kg/day dose is approximately ten times the recommended daily dose of doxycycline, when used as an enzyme inhibitor, for a 60-kg human. {01} .
