Apparatus for temporary male contraception

Method of use of a male contraception apparatus for obtaining temporary sterility during sexual intercourse of a male mammalian individual,

• wherein said male mammalian individual has respective left and right vas deferens connecting between respective left and right testes and an urethra, and further has respective left and right ampulla vas deferens being an enlargement of each of the left and right vas deferens close to a prostate gland and seminal vesicle ducts, the ampulla vas deferens acting as a sperm reservoir and being located close to where the vas deferens meets the seminal vesicle, and
• wherein the male contraception apparatus comprises an implantable hydraulic restriction device configured to restrict vas deferens during a controlled temporary period during sexual intercourse to hinder sperm to reach the urethra during intercourse so as to obtain the temporary sterility and, thus, configured to release the restriction of the vas deferens between intercourses, when implanted, and further configured to be accommodated, when implanted, in a region at least downstream the ampulla and to restrict, when implanted in said region, the vas deferens at least in a downstream region of the ampulla vas deferens, wherein the hydraulic restriction device comprises a constriction device configured to constrict at least one portion of a tissue wall of vas deferens to stop the flow in the vas deferens,
• wherein the male contraception apparatus further comprises a sensor configured to sense a temperature of the male contraception apparatus, and
• wherein the male contraception apparatus further comprises a control device configured to control the operation of the hydraulic restriction device, when implanted in said region between the prostate gland and the ampulla vas deferens, to apply a pressure to said at least one portion of the tissue wall, said pressure being adapted to restrict at least the downstream region of the ampulla vas deferens during sexual intercourse to stop the flow in the vas deferens and, thus, configured to control the release of the restriction of at least the downstream region of the ampulla vas deferens in between sexual intercourses and to hinder sperm to reach the urethra for the controlled temporary period during sexual intercourse, by activation of the hydraulic restriction device in at least the downstream region of the ampulla vas deferens, wherein the control device is further configured to send feedback information pertaining to the temperature to an external device outside the male human being's body, and wherein the control device comprises at least one of:
• a hydraulic reservoir, which is hydraulically connected to the apparatus, wherein the apparatus is adapted to be non-invasively regulated by manually pressing the hydraulic reservoir to operate the restriction device,
• a manual pump operating on the hydraulic reservoir to operate the restriction device to perform a constriction of vas deferens,
• a wireless receiver for receiving signals from a remote control for non-invasively controlling the apparatus, and
• at least one switch implantable in the patient for manually and non-invasively controlling the apparatus,
• wherein the method comprises the use of the male contraception apparatus, by the control of the control device, to restrict the vas deferens in the region downstream the ampulla vas deferens during a controlled period and, thereby, prevent sperms from the ampulla vas deferens to reach the urethra.

• at least one switch implantable in the patient for manually and non-invasively controlling the apparatus,
• wherein the method comprises the step of implanting the male contraception apparatus in said region at least downstream the ampulla vas deferens so as to allow use of the male contraception apparatus to restrict the vas deferens during a controlled period and, thereby, prevent sperms from the ampulla vas deferens to reach the urethra.
