This application provides a method and related equipment for DNA integrity assessment based on single sperm Raman spectroscopy, belonging to the field of sperm quality assessment technology in assisted reproductive technology. This method, based on a machine learning algorithm, directly assesses DNA integrity using the Raman spectra of single sperm, thereby achieving non-destructive screening of individual high-quality sperm in assisted reproductive technology. The process of constructing the algorithm training sample dataset includes a step-by-step fixation and analysis method for sample single sperm: first, Raman spectroscopy testing is performed, followed by fluorescence staining analysis, reducing the impact of sperm position changes during detection, analysis, or staining. Then, optical and fluorescence images of single sperm within preset shape units are matched to determine the validity of the sample single sperm. Finally, a training sample dataset is constructed based on the relevant data of valid single sperm, establishing a correlation between the Raman spectrum of the same single sperm and its sperm chromatin structure analysis results.

The application discloses a kind of oyster-derived bioactive peptides for enhancing male reproductive health, and belongs to the technical field of functional peptides.The peptide product prepared by the method provided in the application has the bioactivity of improving male sperm quality (increasing sperm quantity and survival rate) and erectile dysfunction, and enhancing male reproductive health;It is convenient to eat, has no toxic side effects, and no adverse effects on volunteers and mice involved in the test were observed during the test;The oyster-derived bioactive peptides for enhancing male reproductive health are prepared from high-quality, edible oysters cultured artificially, no toxic and harmful reagents are used in the preparation process, and the added or used components are all beneficial or harmless to the body or components existing in the body / atmosphere, so the safety is very high.

The application discloses a method for evaluating damage of male sperm quality caused by ionizing radiation, and belongs to the technical field of reproductive biology, and comprises the following steps: establishing a dose-effect database model between ionizing radiation dose and male sperm quality based on a logistic regression model, and determining a mapping relationship between sperm quality rating and average time for recovery of fertility; collecting a semen sample to be measured exposed to ionizing radiation, comparing the semen sample to be measured with the dose-effect database model, evaluating male sperm quality rating, and predicting time required for recovery of fertility based on the male sperm quality rating and the mapping relationship.

The application belongs to the field of male infertility disease treatment, and discloses application of a valens enterobacter in improving sperm quality decline. Ileibacterium valens Liu-M1, which is preserved in China Center for Type Culture Collection (CCTCC) and has a preservation number of CCTCC M 20252545. The strain of the application is obtained by using a bacterial separation and identification method to separate and identify a fresh fecal sample of a high-fat diet mouse intervened by inulin. In vivo research finds that the live valens enterobacter can improve the reproductive function of obese male mice, has the effects of improving testosterone secretion, repairing spermatogenesis function, improving sperm quality and embryo development capacity and the like. Experimental results of the application show that the valens enterobacter can significantly improve obesity-related sperm quality decline, which indicates that the valens enterobacter has the potential to become a microbial candidate drug for treating obesity male reproductive function.

This invention, entitled "A Fertilization Culture Medium, Its Preparation Method, and Its Application," belongs to the field of assisted reproductive technology. The technical problem it aims to solve is that existing technologies, due to the generation of sperm DNA fragments during the culture process, lead to a decrease in overall sperm quality, limiting fertilization rate and blastocyst formation rate. This invention proposes a fertilization culture medium that can improve overall sperm quality and thus increase fertilization rate. The key technical points are: a fertilization culture medium comprising the following components: sodium chloride, potassium chloride, alkali metal dihydrogen phosphate, calcium chloride, magnesium sulfate, sodium bicarbonate, sodium lactate, sodium pyruvate, glucose, fructose, disodium edetate, gentamicin, human serum albumin, alanylglutamine, taurine, non-essential amino acids, and testosterone.
