There is provided a method for controlling a flow of sperms in a uterine tube formed by a uterine tube wall of a patient. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the uterine tube wall) at least one portion of the uterine tube wall to influence the flow of sperms in the uterine tube, and stimulating the constricted wall portion to cause contraction of the uterine tube wall portion to further influence the flow of sperms in the uterine tube. The method can be used for restricting or stopping the flow of sperms in the uterine tube, or for actively moving the fluid in the uterine tube, with a low risk of injuring the uterine tube.

A male undergarment providing a comfort barrier between the groin and outerwear with enhancements for promoting male fertility. By use of less restrictive (and confining) clothing adjuncts to the conventional undergarment, an environment for genitalia, primarily the testes, is acquired that will reduce the level of body heat accumulating in the zone or regions proximate those organs. Elements are used that will reduce the normally existing temperatures: a dam, consisting minimally of a fabric partition, for compartmentally segregating genitalia from the loins; thermally isolation, by use of suitable insulative/reflective fabrics, on the dam and between the segregated organs and groin regions; and, a vented, independent, scrotal compartment. Contrary to the modern norm, the genitalia are allowed to assume a more natural, pendulous suspension, one more conducive to the vitality of spermatozoa.

The invention discloses an animal sex control method based on Rbmy gene editing and application. The method controls animal sex by using CRISPR/Cas9 system to specifically cut Rbmy gene on Y chromosome. Rbmy gene encodes a germ cell specific nucleoprotein, this protein is an important factor related to spermatogenesis, and by cutting Rbmy gene, it is possible to deactivate Rbmy gene, thus Y sperm or fertilized ovum with Y sperm is deactivated and cannot develop into a normal embryo, birth ratio of female animals is finally increased and sex control is achieved. Therefore, sex ratio of animal offspring can be controlled through the method so that the ratio of female animals with better economic value is increased and production efficiency and economic effect are greatly improved.
