Polyester sling contraceptive Jul 9, 2009 · The azoospermic effect of the polyester sling seems to be due to (1) creation of an electrostatic field across the intrascrotal structures, and (2) disordered thermoregulation. The female partners were on contraception until the males demonstrated a third consecutive result of azoospermia (very low sperm count). The contraceptive effect of a polyester sling applied to the scrotum was studied in 14 men. Follow-up investigations comprised periodic check of semen character, testicular size, rectal-testicular temperature difference, serum reproductive hormones and testicular biopsy. This created an electrostatic field across the intrascrotal structures, leading to disordered thermoregulation. Contraception 45:439-451, 1992 Contraceptive efficacy of polyester-induced azoospermia in normal men Ahmed Shafik, MD Professor and Chairman, Department of Surgery L Research, Faculty of Medicine, Cairo University, Cairo, Egypt ABSTRACT The contraceptive effect of a polyester sling applied to the scrotum was studied in 14 men. Shafik investigated whether polyester fibers could induce azoospermia—the absence of sperm in semen—and thus act as a form of contraception. Over the course of a year, the study had men wear a polyester sling with the finding that participants developed azoospermia.

In 1992, Shafik performed an interesting experiment in which he attempted to test the contraceptive efficacy of wearing a polyester scrotal sling. After this, the females stopped using contraception. The electrostatic potentials generated by friction between the polyester suspensor and May 1, 1992 · The contraceptive effect of a polyester sling applied to the scrotum was studied in 14 men. "Every 2 weeks, a physician at the Faculty of Medicine at Cairo University in Egypt examined 14 32-47 year old male volunteers wearing a polyester scrotal sling day and night for 12 months to determine if polyester fabrics can act as a contraceptive in men. Prolactin administration, as a contraceptive method is efficient and safe and has the potential to be developed as a male contraceptive. The suspensor was worn for 12 months.

The azoospermic effect of the polyester sling seems to be due to (1 The azoospermic effect of the polyester sling seems to be due to 1) creation of electrostatic field across the intrascrotal structures, and 2) disordered thermoregulation. Nov 19, 2019 · Contraceptive efficacy of polyester-induced azoospermia in normal men. Sep 21, 2017 · He also tested a potential male contraceptive on humans—a polyester sling. All female partners took an oral contraceptive until the men were confirmed as azoospermic, based on three consecutive sperm samples Mar 26, 2023 · The reason for this contraceptive effect? The polyester sling generated electrostatic potentials due to friction between the sling and the scrotal skin, which were greater during the day than at night. The suspensor was Oct 1, 1995 · Two recently developed methods for male contraception--polyester-induced azoospermia and prolactin injection--are described. The azoospermic effect of the polyester sling seems to be due to 1) creation of electrostatic field across the intrascrotal structures, and 2) disordered thermoregulation. Jul 12, 2023 · The study sought to investigate whether polyester fabrics could influence male fertility. Contraception 45:439-451, 1992 Contraceptive efficacy of polyester-induced azoospermia in normal men Ahmed Shafik, MD Professor and Chairman, Department of Surgery L Research, Faculty of Medicine, Cairo University, Cairo, Egypt ABSTRACT The contraceptive effect of a polyester sling applied to the Nov 8, 2023 · The 1992 study by A.

The contraceptive effect of a polyester sling applied to the scrotum was studied in 14 men. Participants only changed the sling when it became dirty, and no complications or adverse reactions were reported. The azoospermic effect of the polyester sling seems to be due to (1) creation of an electrostatic field across the intrascrotal structures, and (2) disordered thermoregulation. ntpwg waslij qwke wxr homz iossczq bnrqw cxd dcilxjd ajestr
