[PMID: 38159442 DOI: 10.1016/j.ejogrb.2023.12.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 12/05/2023] [Accepted: 12/20/2023] [Indexed: 01/03/2024]
Abstract
The viability of sperm is a crucial factor for achieving a successful pregnancy in intracytoplasmic sperm injection (ICSI) cycles. The aim of this study was to evaluate the accuracy of the hypo-osmotic swelling test (HOST) in fresh and frozen-thawed sperm samples of different origins (ejaculated/testicular). A retrospective analysis was conducted on the outcomes of 2167 oocytes subjected to ICSI using motile and immotile-HOST-positive sperm from 2011 to 2023. We evaluated embryonic development, as well as clinical, obstetric, and neonatal outcomes in four groups based on different sperm origins (ejaculated/testicular) and processing (fresh/frozen). When comparing the results of ICSI between motile and immotile-HOST-positive sperm within each group, it was observed that there were no significant differences in the outcomes for fresh samples. However, for frozen-thawed samples, fertilization rates and blastocyst development rates were significantly lower when ICSI was performed with immotile-HOST-positive sperm compared to motile sperm. Of note, clinical, obstetric, and neonatal outcomes were statistically similar across all groups. Our findings indicate that HOST is more reliable in fresh samples than in those subjected to the freeze-thaw process. Nonetheless, HOST is considered a safe method for selecting viable sperm in all subgroups.

Sperm preparation after freezing improves motile sperm count, motility, and viability in frozen-thawed sperm compared with sperm preparation before freezing-thawing process. J Assist Reprod Genet 2017; 35:237-245. [PMID: 28990130 DOI: 10.1007/s10815-017-1050-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2017] [Accepted: 09/15/2017] [Indexed: 10/18/2022] Open
Abstract
PURPOSE The aim of this study is to evaluate which cryopreservation protocol, freezing before or after swim-up, optimizes cryopreservation outcomes in terms of motile sperm count, motility, morphology, and viability, and also to establish whether sperm viability could be assessed based on sperm motility. METHODS Fifty-three fresh and 53 swim-up prepared samples were considered for the first experiment. In parallel, total motility evaluation by CASA system (computer-assisted sperm analyzer) and hypoosmotic swelling test (HOS-test) was performed in each sample to compare the viability results of both methods. In the second experiment, 21 normozoospermic semen samples and 20 semen samples from male factor patients were included. After fresh ejaculate evaluation, the semen sample of each patient was divided into two aliquots, one of them was frozen before swim-up and the other was frozen after swim-up. Motility, sperm count, morphology, and viability were evaluated after thawing. RESULTS A linear regression model allows prediction of HOS-test viability results based on total motility: HOS = 1.38 + 0.97 · TM (R 2 = 99.10, residual mean squares = 9.51). Freezing before sperm selection leads to higher total and progressive motility, total motile sperm count, and viability rates than when sperm selection is performed before freezing (P < 0.005 in all cases). In fact, sperm selection prior to freezing reaches critical values when subfertile patients are considered. CONCLUSIONS To conclude, total motility evaluation can predict HOS-test viability results, resulting in a more objective and less time-consuming method to assess viability. In addition, sperm freezing prior to swim-up selection must be considered in order to achieve better outcomes after thawing, especially in patients presenting poor sperm baseline.

Abstract
Aneuploidy commonly causes spontaneous abortions, stillbirths, and aneuploid births in humans. Notably, the majority of sex chromosome aneuploidies in live births have a paternal origin. An increased frequency of aneuploidy is also associated with male infertility. However, the dynamics and behavior of aneuploid spermatozoa during fertilization in humans have not been studied in detail. Therefore, we compared the frequency of aneuploidy and euploidy in live spermatozoa from normozoospermic men over a 3-day period. To assess the dynamics and behavior of aneuploid spermatozoa, we simultaneously evaluated sperm viability using the hypo-osmotic swelling test and sperm aneuploidy using fluorescence in situ hybridization. Whereas the frequency of viable euploid spermatozoa significantly decreased over 3 days, the frequency of viable spermatozoa with aneuploidy interestingly showed a time-dependent increase. In addition, spermatozoa with abnormal sex chromosomes survived longer. To compared with spermatozoa with other swelling patterns, those with tail-tip swelling patterns had a lower frequency of aneuploidy at all time points. This study revealed the novel finding that the frequency of aneuploid spermatozoa with fertilization capability significantly increased compared to that of euploid spermatozoa over 3 days, suggesting that aneuploid spermatozoa can survive longer than euploid spermatozoa and have a greater chance of fertilizing oocytes.

Spermicidal and contraceptive potential of desgalactotigonin: a prospective alternative of nonoxynol-9. PLoS One 2014; 9:e107164. [PMID: 25243914 PMCID: PMC4171379 DOI: 10.1371/journal.pone.0107164] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2013] [Accepted: 08/13/2014] [Indexed: 12/03/2022] Open
Abstract
Crude decoction of Chenopodium album seed showed spermicidal effect at MIC 2 mg/ml in earlier studies. Systematic isolation, characterization and evaluation revealed that the major metabolite Desgalactotigonin (DGT) is the most effective principle in both in vitro and in vivo studies. The in vitro studies comprises (a) rat and human sperm motility and immobilizing activity by Sander-Cramer assay; (b) sperm membrane integrity was observed by HOS test and electron microscopy; (c) microbial potential was examined in Lactobacillus broth culture, and (d) the hemolytic index was determined by using rat RBCs. The in vivo contraceptive efficacy was evaluated by intra uterine application of DGT in rat. Lipid peroxidation and induction of apoptosis by DGT on human spermatozoa were also studied. The minimum effective concentration (MEC) of DGT that induced instantaneous immobilization in vitro was 24.18 µM for rat and 58.03 µM for human spermatozoa. Microbial study indicated DGT to be friendly to Lactobacillus acidophilus. Implantation was prevented in DGT treated uterine horn while no hindrance occurred in the untreated contra lateral side. At the level of EC50, DGT induced apoptosis in human spermatozoa as determined by increased labeling with Annexin-V and decreased polarization of sperm mitochondria. Desgalactotigonin emerged 80 and 2×104 times more potent than the decoction and Nonoxynol-9 respectively. It possesses mechanism based detrimental action on both human and rat spermatozoa and spares lactobacilli and HeLa cells at MEC which proves its potential as a superior ingredient for the formulation of a contraceptive safer/compatible to vaginal microflora.

Abstract
BACKGROUND The spermicidal activity of oleanolic acid 3-β-D-glucuronide (OAG), an active principle isolated from root extracts of Sesbania sesban, was evaluated. STUDY DESIGN Under the Sander-Cramer test criteria, the sperm-immobilizing activity of OAG was studied using highly motile rat sperm. Sperm mortality and membrane integrity were assessed by supravital staining, hypo-osmotic swelling (HOS), transmission electron microscopy (TEM) and sperm membrane lipid peroxidation (LPO). In vitro microbicidal potential and hemolytic index of OAG were examined in Lactobacillus culture and rat red blood corpuscles (RBCs), respectively. Post-intravaginal OAG application, the in vivo contraceptive efficacy was evaluated in rats. Ames test determined the carcinogenic potential of OAG. RESULTS The minimum effective concentration (MEC) of OAG was 50 mcg/mL. More than 97% of the OAG-treated sperm lost their HOS responsiveness in a dose-dependent manner. TEM and LPO revealed that OAG affected the sperm membrane integrity. OAG declined fertility to zero, was nonmutagenic and was not harmful to lactobacillus. CONCLUSION OAG has significant spermicidal activity that may be explored further.

Abstract
PURPOSE To investigate the prevalence of spontaneously developed tail swellings (SDTS) in human sperm samples that are commonly encountered in the laboratory, and their influence on the hypo-osmotic swelling test (HOS-test). METHODS Ejaculated, epididymal, and testicular sperm were evaluated for SDTS. Further, HOS-test scores were compared with those of vital stains using column washed sperm maintained in the laboratory. RESULTS SDTS, at <10%, was present in all types of sperm samples. The highest and lowest occurrences of SDTS were found in cryopreserved sperm, and column-washed sperm respectively. SDTS can inflate the HOS-test score, and so lower the accuracy of the HOS-test. However, the HOS-test efficiency can be improved by assessing SDTS in the sample. CONCLUSION HOS-test and vital stain cannot be used interchangeably in all circumstances for sperm viability determination. The accuracy of the HOS-test can be enhanced by incorporating SDTS as a correction factor.

Abstract
Glycerol alone or in combination with other additives is one of the most widely used and successful cryoprotectants for human sperm. The glycerol method requires rigorous post thaw sample washing for use in ART and this may lead to low sperm yield from oligospermic samples. In this study the feasibility of the use of sucrose in sperm cryopreservation was explored. Sucrose as cryoprotectant was combined with direct plunging of sample into liquid nitrogen (vitrification) as a freezing method. Sucrose treated sperm from normozoospermic and severly oligozoospermic samples underwent rapid freeze and thaw. Motility and viability were evaluated before freezing (after sucrose equilibration) as well as post freezing (after thaw). The 100 mM concentration of sucrose showed better cryoprotectant features compared to that of higher concentrations (200-1000 mM). Sucrose (100 mM)treated sperm maintained low but acceptable motility (30%) and satisfactory viability (60%) after freezing and thawing. The cryoprotectant capacity of sucrose for normozoospermic and oligozoospermic samples were identical. The sucrose method utilizes rapid freezing of a micro volume of sample and thus quickly freezes, thaws, and maximizes recovery of the sperm from the sample.

Abstract
Spermatozoa were cultured in vitro to monitor time-dependent changes in motility, viability, morphology, and membrane integrity. The degree of preservation of these clinically relevant sperm parameters over time was satisfactory. Extended culture probably can be used as a transient storage for sperm to compensate for a male's inability to produce sperm to synchronize oocyte retrieval in assisted reproduction.
