: Male infertility is rising now-a-days and accounts for major part of infertility cases worldwide. Novel tests are being developed for better detection and management of male infertility. Though there are many tests available for diagnosing male infertility like acrosome reaction rate, hemizona assay, in vivo or in vitro sperm penetration assay, sperm DNA damage tests, but semen analysis is most commonly used initial test for male infertility. It is usually associated with failure to detect cause in many cases, as seminal composition gets affected by a number of factors and can give false reports. Furthermore, it does not give any information about defects in capacitation, sperm Zona Pellucida interaction and sperm’s ability to fertilize oocytes. This results in failure of detection and delayed management of male infertility. Hence, the present review was conducted to identify various sperm proteins that play significant role in spermatogenesis, sperm motility, sperm-Zona Pellucida interaction and fertilization. These proteins can be used in future as markers of male infertility and will aid in better detection and management of male infertility. Methodology: Search for literature was made from 1970 to 2020 from various databases like PUBMED, SCOPUS, Google Scholar on sperm proteins and their role in male fertility using keywords: “sperm protein as bio-markers”, “novel sperm proteins as markers of infertility”, “Sperm proteins essential for capacitation, sperm motility and oocyte fertilization”. Inclusion criteria: All full-length research articles, systematic reviews, meta-analysis or abstracts on sperm proteins and male infertility published in English language in peer-reviewed journals were considered.

Microscopy Data

This work evaluated the effect of in vitro and in vivo treatment with ASA on the morphology of the red blood cells. Blood samples or Wistar rats were treated with ASA for one hour. Blood samples or animals treated with saline were used as control group. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of red blood cells were evaluated under optical microscopy. Data showed that the in vitro treatment for one hour with ASA at higher dose used significantly (p<0.05) modified the perimeter/area ratio of the red blood cells. No morphological alterations were obtained with the in vivo treatment. ASA use at highest doses could interfere on shape of red blood cells.

Sheer Number

Engineered nanomaterials (ENM) have new or enhanced physico-chemical properties compared to their micron-sized counterparts, but may also have an increased toxic potential. Animal and in vitro testing are typically employed to investigate the toxic effects of (nano)materials. The sheer number of ENMs and their physico-chemical parameters make it impossible to only use in vivo and in vitro testing, and modelling technologies are also deployed to find relationships between ENM parameters and toxicity. A heterogenous dataset containing information on 192 nanoparticle endpoints was compiled within the MODENA COST-Action consortium. Here, the available data was mined to identify relationships between nanoparticle properties and cell-death as measured with four cytotoxicity assays. ANOVA, collinearity analyses and classification and regression trees gave indications on potential relations between the NP-properties and toxicity, but could not deliver a robust model. More information and datapoints are necessary to build well-validated models.

Different Doses

The possibility that the «in vivo» treatment with heterologous albumin coupled with diazotized acriflavine may affect the sensitivity of lymphoid cells to the action of acriflavine was studied. Albino mice CFW strain were treated subcutanceusly with the coupled albumin in the presence of complete Freund adjuvant. Lymph nodes from control and immunized animals, fifteen days after the treament, were cultured «in vitro» in the presence of different doses of acriflavine (from 0.5 to 4 μg/ml). The action of acriflavine was evaluated as the growth of cultures, the percent of lymphoid cells in the different phases of differentiation and the percent of proliferating cells after incubation for 24 hours in the presence of 3H thymidine. Results show that lymphoid cells of immunized mice are less sensitive to the citotoxic activity of acriflavine than those of the controls. Acriflavine, at low doses, reduces the growth of normal cultures and the proliferative activity of immature elements. At the highest doses the proliferation area is almost completely absent and the elements still present are strongly degenerated. Acriflavine, at the concentration able to reduce or to inhibit the growth of control cultures, is ineffective in altering the ratio of immature elements in cultures of immunized animals. The ability of these elements to incorporate 3H thymidine is also unchanged.
