The invention relates to a culture solution for bovine IVF and a method for improving bovine IVF. The method for bovine IVF comprises the following steps: washing a mature cumulus-oocyte complex in afertilization culture solution, transferring the mature cumulus-oocyte complex into the fertilization culture solution, and putting the fertilization culture solution into an incubator for later use;taking a frozen seminal tubule from liquid nitrogen, performing unfreezing in a water bath at 37 DEG C, injecting seminal fluid into a centrifuge tube containing a seminal fluid preparation culture solution, and discarding a supernatant after centrifugation; adding the seminal fluid preparation culture solution into the centrifuge tube, resuspending sperm precipitate, and taking a proper sperm suspension for sperm counting; and adding the sperm suspension with the calculated volume into fertilization culture liquid drops containing oocytes, placing a culture tray into the incubator, and carrying out sperm-ovum co-incubation to complete IVF operation for embryo in-vitro culture. The fertilization culture solution and the seminal fluid preparation culture solution contain sodium pyruvate, heparin and other components. The method can significantly improve the efficiency of bovine IVF.

In a new pharmaceutical combination, the herb, Vitex agnus-castus (chasteberry), enhances hormone balance by increasing progesterone release and, therefore, ovulation frequency. The antioxidants, green tea, vitamin E, and selenium, improve overall reproductive health. L-arginine, an amino acid, stimulates the reproductive organs by improving circulation. Folic acid, vitamins B6 and B12, iron, zinc and magnesium help promote womens' fertility. Sperms are highly susceptible to free radical or oxidative damage from environmental toxicants and natural aging. Vitamins C and E, coenzyme Q10 and selenium are all potent antioxidants that help improve sperm counts and quality. Ferulic acid, an antioxidant found in Dong quai, also improves sperm quality. Zinc and B vitamins (B6, B12 and folate) are critical nutrients in male reproductive systems for hormone metabolism, sperm formation and motility. The amino acid, L-carnitine, promotes formation of healthy sperm.

Test kits for assessing male fertility include a sample holder containing at least one sample chamber, a laser light source, and a light detector to detect scattered light intensity from the sample chamber. The sample holder may include multiple sample chambers connected by sperm swim channels. The test kit may have a housing with a maximum linear dimension of no more than 100 mm. Processing circuitry may be provided that is configured to produce a sperm count and/or sperm motility measurements by processing data from scattered light intensity measurements.

The present invention relates the function of Dickkopf 3 (Dkk3 ) in testis using shRNA mediated knock down model. Specifically, the present invention provides knock down model comprising reduction in Dkk3 activity. The knock down model of Dkk3 consisting of non human vertebrates which have, incorporated in their genome, shRNA construct targeting mammalian Dkk3 gene exhibits low testis weight, low sperm count and has low litter size. The knock down model displays disrupted seminiferous tubules and are subfertile. The present invention model has a role in sex determination as its interruption leads to sex reversal of XY gonads, converting males to females. Sex reversal role of Dkk3 knock down model can find its utility in agricultural applications. The present invention describes Dkk3 as a dual function protein which is associated with sex determination as well as is essential for the process of spermatogenesis. Such testicular functional studies are useful as a model for various disease states of infertility or subfertility and for identifying a potential treatment to overcome idiopathic infertility.

The feed is prepared from the following raw materials: bean pulp, corn flour, herbage, epimedium herb, semencuscutae, fructus lycii, fragrant-flowered garlic, bone meal, fructus crataegi and an additive, wherein the additive is prepared from oil meal and pancreatic powder. The feed for the breeding cattle provides balanced nutrition for the breeding cattle which frequently mate, can remarkably enhance the physique of the breeding cattle, promotes the gonepoiesis of the breeding cattle, increases the ejaculatory amount and sperm count of the breeding cattle, and improves the semen quality of the breeding cattle, thus improving the reproductive capacity of the breeding cattle.

The invention relates to a method for culturing and cryopreserving bovine in-vitro fertilization embryos. The method comprises the following steps of: washing a mature cumulus-oocyte complex in a fertilization culture solution, transferring the mature cumulus-oocyte complex into the fertilization culture solution, and putting the mature cumulus-oocyte complex into an incubator for later use; taking a frozen sperm tubule from liquid nitrogen, unfreezing, taking a sperm suspension, and counting sperms; adding the sperm suspension into fertilization culture solution drops containing oocytes to co-incubate the sperms and the oocytes, completing in-vitro fertilization operation, completely removing granular cells around the embryos by using an oocyte stripping needle, putting the embryos into an embryo culture solution for culturing, transferring available embryos into a freezing solution, and putting the embryos into liquid nitrogen for cryopreservation; and when the cryopreserved embryos need to be used, taking the tubule from the liquid nitrogen, transferring the tubule into an unfreezing solution, putting the embryos into small drops of the embryo culture solution for culturing, and completing the unfreezing process. The invention further relates to the used freezing solution and the used unfreezing solution. According to the method, the survival rate of the bovine in-vitro fertilization embryos after cryopreservation and unfreezing can be remarkably increased.

Male infertility due to reduced sperm count has received dramatically increased scientific attention in recent years, particularly the effect of excessive testicular heat on sperm motility. Currently all products designed for testicular cooling are prohibitively cumbersome, or potentially toxic. While ice can be applied directly to the testicles, this invention provides and a convenient and comfortable alternative that does not exist today: underwear specifically designed to be fitted with a freezable gel pack, permitting users to keep moving around. Researchers increasingly believe that this sort of cooling can have a positive effect on sperm health, perhaps providing another alternative to other expensive and invasive fertility treatments.
