182 results about "Semen quality" patented technology

Semen quality is a measure of the ability of semen to accomplish fertilization. Thus, it is a measure of fertility in a man. It is the sperm in the semen that is of importance. Semen quality involves both sperm quantity and quality. Decreased semen quality is a major factor of male infertility.

Semen analysis

A method for measuring the total sperm concentration (TSC) in a sample is described and includes: (i) placing the sample in a transparent container between a synchronically pulsed light source and a photodetector; and (ii) measuring the optical absorbance of the sample in the range of 800-1000 nm, the TSC of the sample being proportional to the absorbance. Also described is a sampling device for use in optically analyzing a biological fluid, a method for measuring motile sperm concentration (MSC) in a semen sample, a method of determining the average velocity (AV) of sperm cells and a system for analyzing semen quality including means for measuring TSC, means for measuring MSC; and a video visualization system.

Medicine for treating male oligozoospermia and improving semen quality and preparation method of medicine

The invention relates to a medicine for treating male oligozoospermia and improving semen quality. Various natural edible plant medicines such as Rhizoma Polygonati, Fructus Lycii, Cordyceps militaris (L.) Link., Fructus Rubi, Fructus Mori, Fructus Hippophae, Semen Coicis, Radix Ginseng, and Concha Ostreae (calcined) serve as raw materials, are combined suitably, and jointly have effects of invigorating the spleen and replenishing Qi, and nourishing the kidney and replenishing essence, Lepidium Meyenii contains macaenes and macamides which are used as active substances has effects of promoting sexual function, increasing the number of sperms and improving activity of the sperms, selenium yeast, aminoacid, L-carnitine tartrate, calcium carbonate and fructose can strengthen and protect energy metabolism of the sperms, taurine and vitamin effectively remove reactive oxide species and protect activity of the sperms, and folacin can promote maturity of the sperms and improve functions of the sperms. The medicine is reasonable in composition, and the synergistic effect of various components is utilized, so that the medicine is remarkable and lasting in treatment effect, safe and reliable and convenient to take orally, and can effectively promote spermatogenesis, improve survival rate of the sperms and improve activity of the sperms.

Fresh-pig-semen preserving long-acting dilution powder, preparing method thereof and application thereof

The invention discloses a fresh-pig-semen preserving long-acting dilution powder, a preparing method and an application. The fresh-pig-semen preserving long-acting dilution powder is prepared from, by weight, 35 parts to 40 parts of glucose, 1.2 parts to 1.4 parts of oxalic-acid tetracetic acid sodium, 4 parts to 8 parts of sodium citrate, 1.2 parts to 1.4 parts of sodium bicarbonate, 0.7 part to 0.8 part of potassium chloride, 0.4 part to 0.6 part of polyvinyl alcohol, 0.1 part to 0.2 part of cysteine, 0.4 part to 0.6 part of inositol, 1.0 part to 1.5 parts of penicillin and 1.0 part to 1.5 parts of streptomycin. A use method of the fresh-pig-semen preserving long-acting dilution powder includes the steps that after being collected, pig semen is diluted through 1 L of diluent prepared from the dilution powder, the diluted semen can be preserved in a 17-DEG-C constant-temperature refrigerator for 5 days to 7 days, the quality of the semen can still meet the semen deposition requirement, and the semen live rate is higher than 60%. The fresh-pig-semen preserving long-acting dilution powder, the preparing method and the application are achievements obtained through more than 200 times of tests in three years; the application to a pig farm proves that the quality of the fresh-pig-semen preserving long-acting dilution powder is high, insemination capacity is still achieved after the semen is preserved for 5 days, and the effect is stable.

Method for inducing Verasper moseri sperm maturation and enhancing activity by using slow releasing hormone

The invention relates to a method for inducing Verasper moseri sperm maturation and enhancing activity by using slow releasing hormone. Sexually mature parent fish is selected, and salmon gonadotropin releasing hormone (sGnRH) is implanted into the back muscle (35 mu g / kg) to promote the sperm to finally become mature and enhance the sperm activity to more than 85-90%, thereby increasing the fertility rate by 4-7 times. The method has the advantages of low reproductive menace for parent fish, high survival rate and sex gland maturation rate of parent fish, and favorable spawning effect, and can obtain massive high quality oosperms. The method is a complete control technique. When the sperm quality starts to degrade, implantation is carried out on the parent fish for the second time, and the repeating effect is good. The method can ensure the large-scale artificial propagation of fries to be smooth.

Pig semen normal temperature liquid negative pressure preservation device and method

The invention relates to a pig semen normal temperature liquid negative pressure preservation device which comprises a closed container, a rubber plug, a connecting tube, a vacuum pump and a semen preservation tube, wherein the rubber plug is arranged at the upper part of the closed container; one end of the connecting tube penetrates through the rubber plug and extends into the inside of the closed container, and the other end of the connecting tube is connected with the vacuum pump; the semen preservation tube is arranged at the bottom inside the closed container. The invention further relates to a method for preserving pig semen by utilizing the device. The method comprises the following steps: removing upper seminal plasma of the fresh pig semen through a centrifugal machine and then diluting the upper seminal plasma with a diluent. The semen preservation tube is put in the closed container, and the closed container is covered with the rubber plug with a valve, and the connecting tube is connected with the vacuum pump with a vacuum meter; the vacuum pump is started to pump air out of the closed container. The pig semen normal temperature liquid negative pressure preservation device provided by the invention has the benefit that as the pig semen is subjected to normal temperature liquid preservation by using the device, the preservation time can be prolonged to 9-13 days, so that the sperm and semen quality are significantly improved.
