Abstract:

Biochemical analyses of the seminal fluid would provide valuable information on the function of the accessory genital glands under normal and pathologic conditions, especially in case of infertility. This review presents several biochemical markers, like pH of the semen, as well as biochemical parameters of the secretion of prostate, epididymis and seminal vesicles, their role, methods of measure, and their reference values.

Abstract:

The general objective of this in vitro study was at first to evaluate copper (Cu) content in the cell sediment and seminal plasma fraction and compare their relationship with basic motility characteristics and secondly expand the knowledge of its impact on the fertilization potential of the spermatozoa. Semen samples were collected from 12 breeding bulls. The motility analysis was carried out using the Computer Assisted Semen Analysis (CASA) system. The mean value for the percentage of motile spermatozoa (MOT) was 91.24±5.17% and the progressive motility of the spermatozoa (PROG) as 88.

The composition of seminal plasma of individual sires varies and so does the fertilizing ability. Micro and macro elements along with seminal enzymes, hormones, proteins, and lipids contained in seminal plasma are essential for the proper physiological function of spermatozoa. However, elevated levels against the normal physiological values, especially in the case of trace metals, result in the production of reactive oxygen species. The deficiency of antioxidants in the seminal plasma that could scavenge free radicals causes an impairment of spermatozoa quality. Ejaculates were obtained from 1

Background: Ammonia, urea, uric acid, and creatinine are the major non-protein nitrogenous compounds (NPNs). It is reported that the concentration of NPNs in the seminal plasma of normal and infertile individuals is different and sperm is affected by NPNs. Objectives: The aim of this study was to determine the quantities of ammonia, urea, uric acid, and creatinine in seminal plasma and the correlation of these compounds with the fertilization rate after an intracytoplasmic sperm injection (ICSI). Methods: The levels of ammonia, urea, uric acid, and creatinine were determined in seminal plasma

Abstract:

Several studies have addressed the impact of viral infections on male infertility. However, it is still unknown whether human papillomavirus (HPV) can alter seminal parameters. The aim of this study was to determine the prevalence of HPV in the semen of male partners of couples seeking fertility evaluation. Additionally, we assessed the possibility that HPV infections affect seminal parameters. A total of 229 semen samples were collected from men in the Sperm Analysis Section of São Camilo Laboratory of Maringá, Brazil, between October 2015 and March 2016. Basic seminal parameters were analyze

Abstract:

Radical prostatectomy (RP) is the most common primary treatment for prostate cancer. About 40% of those with high-risk pathologic features, such as a positive margin or seminal vesicle involvement, will develop biochemical failure at some point in the future. Radiotherapy (RT), with or without concurrent androgen deprivation, has been used liberally in the management of men with a rising prostate-specific antigen (PSA) after RP, based mostly on relatively small retrospective series. Factors such as the prostatectomy Gleason score, seminal vesicle invasion, absolute pre-RT PSA level, and pre-RT

Abstract:

Seminal plasma purportedly plays a critical role in reproduction, but epididymal spermatozoa are capable of fertilisation following deposition in the uterus, calling into question the biological requirement of this substance. Through a combination of direct observation of spermatozoa in utero using probe-based Confocal Laser Endomicroscopy, in vivo assessment of sperm fertility and in vitro analysis of various sperm functional parameters, this study investigated the role of seminal plasma in spermatozoa transit through the cervix of the ewe. Following deposition in the cervical os, epididymal

Abstract:

This study monitored the chemical and biochemical composition of bovine seminal plasma (SP). Freshly ejaculated semen (n = 20) was aliquoted into two parts. The first aliquot was immediately assessed to determine the sperm motion parameters. Another motility measurement was performed following an hour-long co-incubation of spermatozoa with SP at 6 °C. The other aliquot was processed to obtain the SP. Seminal plasma underwent the analyses of chemical composition and quantification of selected proteins, lipids and RedOx markers. Determined concentrations of observed parameters served as input da

Abstract:

This study evaluated seasonal variation in seminal parameters and post-thaw motility after cryopreservation in buffalo bulls. To conduct this study, five Nili Ravi buffalo bulls were placed at a private semen production unit, Al-Haiwan Sires, Sahiwal, under uniform nutritional and management conditions. Semen samples were taken twice a week from May 2019 to April 2020. A total of 389 ejaculates were collected with the help of a pre- warmed artificial vagina (42ºC) and then transferred to the semen evaluation room. Then, semen ejaculates were evaluated for physical characteristics, including ej
