Background: Cryopreservation enables semen to be preserved at subzero temperatures, usually at -196 degrees C. There is a need in preparing good extender for the semen to be cryopreserved until use, especially in the field of assisted reproduction.
Objective: To elucidate the apt extender for preserving both infertile and fertile samples for a minimum period and to check the post thaw results for various extenders used.
Materials And Methods: A total of 103 samples were collected for this research, and after semen analysis the semen samples were categorized into oligospermia (n = 20), oligoasthenospermia (n = 22), asthenospermia (n = 24), normospermia (n = 28), and control (n = 9).
Results: The extender supplemented with various antioxidants yields better results when compared to all the other extenders in case of fertile and infertile samples.
Conclusion: Supplementing semen extender with antioxidants and various ingredients is the concern in designing an apt semen extender recipe. This research prescribes antioxidant extender (E4) to preserve the infertile and fertile semen samples for the purpose of research and also for doing assisted reproduction.

The importance of oxidative stress in the aetiology of male infertility has occasioned numerous clinical trials designed to assess the potential of antioxidants for treating this condition. These trials have not returned definitive results, probably because they have never selected participants on the basis of oxidative stress. Clearly, if a moderate to severe state of oxidative stress does not exist in semen, antioxidants can hardly be expected to improve fertility.

Background: Extracellular vesicles (EVs) are essential for cell-to-cell communication because they transport functionally active molecules, including proteins, RNA, and lipids, from secretory cells to nearby or distant target cells. Seminal plasma contains a large number of EVs (sEVs) that are phenotypically heterogeneous. The aim of the present study was to identify the RNA species contained in two subsets of porcine sEVs of different sizes, namely small sEVs (S-sEVs) and large sEVs (L-sEVs).

Identification of body fluid stain at crime scene is one of the important tasks of forensic evidence analysis. Currently, body fluid-specific CpGs detected by DNA methylation microarray screening, have been widely studied for forensic body fluid identification. However, some CpGs have limited ability to distinguish certain body fluid types.

There are many applications of soybean lecithin (SL) and cholesterol-loaded cyclodextrin (CLC) in sperm freezing processes. To the best of our knowledge, there have been few cases of the combined use of SL and CLC in freezing rooster semen. We investigated the effects of CLC, SL, and their combination on rooster sperm cryodamage.

Tobacco smoke has numerous adverse effects on both human and animal health, including impaired reproductive function. Recent research has explored environmental exposure in dogs, investigating various biological matrices. However, no data are currently available on the presence of cotinine, a nicotine metabolite, in the canine ejaculate.
