Embodiment

[0024] The dioscin in vitro sperm nutrient solution of the present invention is a liquid mixed with polysaccharide extracted from yam raw material and normal saline, and the ratio of yam polysaccharide to normal saline is 1 g of yam polysaccharide: 10 ml of normal saline.

[0025] The preparation method of the in vitro sperm nutrient solution of yam is as follows: take yam as raw material, wash it, dry it at 60° C. for 2 hours, then pulverize it, put it into 0.8% normal saline and soak it for 1 hour, mix yam raw material with normal saline The ratio is 100g: 900-1150 milliliters, the ratio can be: 100g: 900 milliliters, 100g: 1150 milliliters or 100g: 1100 milliliters, etc., the preferred scheme is: the ratio of raw material yam and normal saline is 100g: 1000 milliliters . Then put the soaking solution in a container and heat it at 100°C, take it out, filter and remove the slag to obtain the yam extract; dry the yam extract at 60°C for 1 hour to obtain a dried product; Put t...

Abstract

The invention discloses a yam in vitro sperm nutrient solution, the preparation method and the application of the solution. The solution is mixed by polysaccharide extracted from yam raw material and normal saline, wherein the ratio between the yam polysaccharide and the normal saline is that 1 gram to 10 millimeter. The preparation method is: yam raw material is cleaned, dried and smashed, and is drenched in normal saline; then the soak is put in a vessel, heated under conditions between 95 to 105 degrees centigrade, and filtered to produce yam extract. The application of the yam in vitro sperm nutrient solution is: the yam in vitro sperm nutrient solution is mixed uniformly with semen with a liquid volume ratio of 1 to 1 to cultivate sperm and activated sperm. The invention is capable of enhancing the sperm mobility by 35 to 56 percent without any damage to or side effects on sperm, so the product with such high effects can replace imported product. Besides, the price is greatly reduced compared with imported goods.

Description

technical field [0001] The invention relates to a sperm nutrient solution, which is a yam in vitro sperm nutrient solution and a preparation method and application thereof. Background technique [0002] Infertility patients who are infertile due to low sperm motility account for a relatively large proportion of infertility patients. There are many types of oral drugs for the treatment of this type of infertility. It will take several years to take effect orally, which will cause greater economic burden and psychological pressure to the patient, and is prone to various discomforts, which has a certain impact on the health of the patient. For this reason, in recent years, international studies have begun to use sperm nutrient solution to cultivate the vitality of the patient's sperm in vitro, and finally achieve the purpose of enhancing sperm vitality. This nutrient solution that my country uses at present is all imported products, and is expensive, and generally all contains...
