Claims

1. A method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes which comprises applying continuous ultrasonic vibrations selectively only to the testes of said animal at an effective power level and at a frequency sufficient to penetrate said scrotal testes and for a sufficient time to temporarily or permanently suppress spermatogenesis while causing the subject substantially no discomfort.

2. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 1 wherein the continuous ultrasonic vibrations are transmitted by an ultrasound applicator connected to a continuous ultrasound generator, said continuous vibrations transmitted to said scrotal testes through a coupling agent in which said scrotal testes are immersed.

3. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 2 wherein the coupling agent is contained in a vessel accommodating the scrotal testes to be sonicated.

4. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 3 wherein the coupling agent is water.

5. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 3 wherein the ultrasonic vibrations have a frequency between about 500 KHZ and about 5000 KHZ.

6. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 5 wherein the effective power level of the ultrasound applicator is between about 0.25 watt/cm.sup.2 and about 3 watt/cm.sup.2.

7. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 6 wherein the effective power level of the ultrasound applicator is between about 0.5 watt/cm.sup.2 and about 2 watt/cm.sup.2.

8. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 7 wherein the effective power level of the ultrasound applicator is between about 0.5 watt/cm.sup.2 and about 1 watt/cm.sup.2.

9. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 8 wherein the time is between about 3 min. and about 15 min.

10. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 9 wherein the coupling agent is water and the ultrasonic vibrations have a frequency of 1100 KHZ .+-. 10 KHZ, the effective power level is 1 watt/cm.sup.2 and the time is 10 min.

11. The method of suppressing spermatogenesis in domestic animals, excluding humans, having scrotal testes according to claim 10 wherein the effectiveness of the method is monitored by a sperm count, said method being repeated until the desired count is reached.
