Spermatozoa have a remarkable epigenome in line with their degree of specialization, their unique nature and different requirements for successful fertilization. Accordingly, perturbations in the establishment of DNA methylation patterns during male germ cell differentiation have been associated with infertility in several species. While bull semen is widely used in artificial insemination, the literature describing DNA methylation in bull spermatozoa is still scarce.

Flow cytometry based evaluation of sperm parameters is advantageous over the traditional microscope based evaluation. Many sperm parameters can be measured within short time period and with high accuracy. For this study, semen from six Jersey crossbred bull were collected. Semen parameters like sperm for viability and acrosomal integrity were analyzed by flow cytometry.

Infertility is becoming a major problem among the marital couples and in at least 50% of the cases, the male partners are the only contributor to the problem. Many of these men are diagnosed with no etiology and hence they are idiopathic cases. The current study was planned to generate some markers in infertile males in order to find a preventive measure that could be taken for effective cure of this serious issue.

Semen sample has to be analyzed to determine the fertilization capacity of sperm. This helps in the efficient use of semen sample for cryopreservation and their further use in artificial insemination. The current methods used to analyze semen just indicate a predictive fertility status, not an actual fertilization capacity. Certain mRNA population / transcripts which are present in spermatozoa are found to have a potential role in fertilization capacity.

The objective of the current experiment was to investigate the various semen characteristics of two indigenous breeds of chicken namely Nicobari and Ankleshwar, as such data were not yet reported. Freshly ejaculated semen samples were collected from twenty breeder roosters of each breed and subjected to physical and biochemical analysis. Immediately after collection, the semen volume of individual birds was recorded using tuberculin syringe and further analysed for seminal motility, concentration and percentage of live, dead and abnormal spermatozoa using standard procedures.

The objective of the research was to study the protein content and electrophoretic profile of specific fractions of Large White Yorkshire (LWY) boar semen. Sperm rich fractions (SRF) of semen were collected from four sexually mature LWY boars as fractions of 10 mL each, by gloved hand method. For analysis, the first 10 mL of the SRF, rest of the SRF and sperm free fraction (SFF) were collected separately.

The present communication reports a case of Sahiwal cattle bull which was presented with the chief complaint of infertility for last six months. Semen analysis performed on periodic ejaculates revealed watery consistency along with oligospermia. Critical examination using ultrasonography was suggestive of bilateral testicular fibrosis as the chief etiology of infertility. The animal was found unfit for breeding and it’s culling from the routine breeding programs was advised.

There is a need to improve current practices in Asia with regard to selection of cattle for breeding purposes, for both dairy and beef production. For many years, most of the countries in the region have been importing cows, bulls, and semen, largely from the temperate regions of the world, and using them to ‘upgrade’ the genetics of their existing herds of indigenous cattle for producing ability. However, and based on current evaluation of production levels and the productivity of cattle and buffalo, some doubts exist regarding the need and wisdom to continue this practice.

The zinc-binding protein semenogelin I is the major structural component of the gelatinous coagulum that is formed in freshly ejaculated semen. Se-menogelin I is a rapidly evolving protein with a primary structure that con-sists of six repetitive units, each comprising approximately 60 amino acid residues.

Commodity-level analysis illustrates the size of opportunities and the importance of technology. In many African countries with large amounts of suitable but currently uncultivated land, transfers of technology could pro- vide large benefits to local populations. To reduce risks and increase benefits, greater effort will be needed to identify local comparative advantage, assess the technical viability of proposed investments, improve weak institutional frameworks for land governance, and level the playing field for smallholder competitiveness.

One key to the success of PPHE at Stony Brook has been the efforts by PPHE leaders to inform and collaborate with other university offices and schools. Stony Brook University Hospital’s Chief Operating Officer learned about PHE during a visit to the department of pediatrics. Presentations on PPHE were made to directors and members of the Department of Health Care Policy and Management, the Department of Psychiatry, and the schools of Medicine, Public Health, Health Technology Management, and Social Welfare.

Medicaid Services (CMS) under the Clinical Laboratory Improvement Act (CLIA). The objective of the CLIA program is to ensure quality laboratory testing by establishing standards for accuracy, reliability, and timeliness of patient test results. A laboratory is defined as any facility that tests specimens derived from humans for the assessment of health or the diagnosis, prevention, and treatment of disease. CLIA regulations, published in 1992, are based on the complexity of the test method; thus, the more complicated the test, the more stringent the requirements.

Normal functioning of reproductive systems of male and female, no doubt is expected of all individuals. But one of the vagaries of nature is aberration of this function. While fertility is an essential ingredient for survival and continuity of species, not all couples are capable of furthering their families. So the problem of infertility finds its place in the recorded history of ancient civilisations of Babylonia, Persia and Greece.1 Goddesses of fertility, fertility rites, and superstitions encompassing the process of birth are mentioned in the history of these civilisations.
