Commercial freeze extenders have different composition and ratio of cryoprotectors; freezing and thawing protocols are different for each extender. The aim of this experiment was to observe the effect of thawing curve in stallion frozen semen with 2 commercial extenders. Two ejaculates from each of 9 stallions of different breeds (Quarter Horses and Mangalarga Marchador) were used. Semen was collected using an artificial vagina, and the ejaculate was divided into 2 groups following the manufacture's protocol: group 1 (INRA), in which the semen was diluted 1 : 1 with the extender INRA 96TM (IMV, Paillette Crista, France) and group 2 (BC), in which the semen was diluted (1 : 1) with the extender Botu-SemenTM (Botupharma, Brazil). The samples of the 2 groups were centrifuged at 600 × g for 10 min, the supernatant was discarded, and the pellet was resuspended with INRA FreezeTM (group INRA, IMV) and with BotucrioTM (group BC, Botupharma) at the concentration of sperm 100 × 106 sperm mL–1. After this, the semen was packaged in 0.5-mL straws. For each group the freezing process was carried out according to the manufacturer's instructions. The straws were thawed in a water bath with 3 different thawing curves: 37°C for 30 s (37/30), 46°C for 20 s (46/20), and 75°C for 7 s (75/7) before analysis. The aim of these rates is to keep the semen in 37°C post-thaw. The sperm kinetic analysis was performed by computerized method (CASA, HTM-IVOS, IMV, USA) and the analysis of plasma membrane integrity by flow cytometer (BD LSR Fortessa, Becton Dickinson, Mountain View, CA, USA). Data of sperm kinetic and of plasma membrane integrity were compared among the 3 thawing curves for one extender using analysis of variance. Differences were considered significant at a probability level of 5%. No differences were observed in total motility (%, BC 37/30 = 72.8 ± 14.4; BC 46/20 = 70.0 ± 14.2; BC 75/7 = 70.3 ± 12.0 v. INRA 37/30 = 57.2 ± 19.1; INRA 46/20 = 50.0 ± 21.9; BC 75/7 = 58.8 ± 20.8), progressive motility (%, BC 37/30 = 36.9 ± 8.2; BC 46/20 = 34.4 ± 10.5; BC 75/7 = 33.6 ± 7.8 v. INRA 37/30 = 25.3 ± 12.7; INRA 46/20 = 21.9 ± 13.9; BC 75/7 = 28.9 ± 14.8), rapid sperm (%, BC 37/30 = 59.7 ± 16.4; BC 46/20 = 56.8 ± 17.1; BC 75/7 = 58.1 ± 14.9 v. INRA 37/30 = 38.3 ± 20.9; INRA 46/20 = 35.3 ± 22.9; BC 75/7 = 44.4 ± 23.8), and plasma membrane integrity (%, BC 37/30 = 49.1 ± 14.8; BC 46/20 = 43.1 ± 13.1; BC 75/7 = 46.7 ± 11.8 v. INRA 37/30 = 32.2 ± 10.7; INRA 46/20 = 29.6 ± 10.1; BC 75/7 = 37.4 ± 9.1) among the 3 thawing curves for INRA and BC groups. In this study, we can conclude there is no influence of the 3 tested thawing curves in sperm quality for stallion frozen semen with INRA Freeze and Botucrio extenders.

Study was conducted to compare the semen quality and fertility of liquid stored semen for three days and frozen-thawed semen in the north-eastern region of India. For liquid semen, the semen ejaculates were extended in Beltsville Thawing Solution (BTS) extender and preserved at 17°C for three days. For cryopreservation, semen was diluted Lactose-egg yolk-glycerol extender and frozen in straw using programmable freezer with freezing rate of 40°C/min from -6 to -140°C. The preserved evaluated for sperm motility, viability, plasma membrane integrity and fertility. The results revealed that the liquid stored semen has maintained the sperm motility and viability up to day 3 without significant reduction. Similarly the plasma membrane integrity did not differ significantly up to day 2, but it was significantly (P less than 0.05) reduced on days 3 in liquid stored semen. After freezing and thawing, the mean sperm motility, viability and plasma membrane integrity were 58.25 ± 2.96%, 64.75 ± 2.47% and 47.06 ± 2.02%, respectively. These parameters were significantly (PP less than 0.01) lower as compared to the liquid stored semen from day 0 to day 3. After insemination with liquid semen, the farrowing rate was 77.7%, 80.76%, 73.07% and 69.8%, respectively from day 0, day1, day 2 and day 3. The pregnancy rate, farrowing rate and litter size did not differ significantly among different days of liquid storage. These parameters were significantly (PP less than 0.01) lower in frozen semen as compare to that of liquid stored semen. The study concluded that the liquid semen stored up to three days is more efficient than frozen-thawed semen in terms of preserving sperm quality and fertility.

Several factors can interfere with sperm cryopreservation resistance, especially the genetic factors and those related to the plasma membrane composition of the sperm and seminal plasma. However, it is still unclear if the same factors that confer freezing resistance will perform the same role during the cooling process. Thus, the aim of this study was to determine the relation between the resistance to freezing and cooling processes in stallions. Two ejaculates from each of 75 stallions were used. All animals showed good quality of fresh semen (total motility higher than 60% and plasma membrane integrity higher than 50%). After collection, the semen was diluted 1 : 1 with commercial skim milk-based extender (Botu-SemenTM, Botupharma, Brazil) and then a part was designed to cooling and the another to freezing. The cooled semen was divided into 2 groups: Group PS, in which the semen was diluted with Botu-SemenTM at a concentration of 50 × 106 sperm mL–1, and Group SPS, which was subjected to a centrifugation at 600 × g for 10 min and resuspended with Botu-SemenTM at 50 × 106 sperm mL–1. Semen samples from both groups were placed in the same cooling passive system for a period of 24 h/5°C. To accomplish the freezing process, the semen sample was subjected to centrifugation at 600 × g for 10 min. The supernatant was discarded, and the pellet was re-suspended in a Botu-CrioTM. The straws were frozen according to the manufacture. The sperm parameters from fresh semen, cooled semen for 24 h with and without seminal plasma, and frozen semen were evaluated for kinetics by computer-assisted semen analysis and for plasma membrane integrity (IMP%) by epi-fluorescence microscopy. The animals were classified in relation to their resistance to cooling and freezing processes as follow: “bad coolers” – reduction in sperm total motility and in plasma membrane integrity higher than 35% after 24 h of cooling in samples with seminal plasma; “good coolers” – reduction in sperm total motility and in plasma membrane integrity lower than 35% after 24 h of cooling in samples with seminal plasma; “bad freezer” – sperm total motility lower than 40% and progressive motility lower than 20% in seminal sample after thawing; “good freezer” – sperm total motility higher than 60% and progressive motility higher than 30% in seminal sample after thawing. The comparison between the resistance to cooling and freezing processes was performed by Fisher's exact test. The level of significance was 5%. No difference (P < 0.05) between the resistance to cooling and freezing processes was observed. The percentage of stallions “good freezer” and “good cooler” was 54%, “good freezer” and “bad cooler” was 22.6%, “bad freezer” and “good cooler” was 12%, and “bad freezer” and “bad cooler” was 10.6%. Within stallions classified as “good freezer” and “bad cooler,” 52.9% also were “good cooler” when the seminal plasma was removed before the cooling process, and 47.1% remained as “bad cooler.” The result of this study demonstrates that there is a strong relation between the resistance to cooling and freezing processes in stallions. In stallions categorized as “bad cooler,” the seminal plasma presents a major influence on the quality and longevity of cooled semen.

The Impact

Aim: Different types of extenders have a variety of components which show the tolerance effect on sperm protection during freezing procedures. In the present study, we have examined the impact of the extenders HF-20 and Tris, which were locally manufactured, and they are competing with commercial extenders INRA Freeze® (IMV Technologies, France) and EquiPlus Freeze® (Minitube, Germany) on the quality of horses frozen semen. Materials and Methods: A total of 15 ejaculates from three healthy stallions were collected and cryopreserved in the same environment. Each semen sample collected was divided into four equal parts and processed. All samples were analyzed before and after freezing for motility, viability, plasma membrane integrity, and morphology. Furthermore, twenty mares were inseminated using post-thawed semen. Results: There were no differences observed among all extenders in all the parameters before freezing. Sperm cryopreserved using HF-20 showed better motility, viability, and plasma membrane integrity than Tris extender. The Tris extender showed the most inferior quality of post-thawed semen between all the extenders. HF-20, INRA Freeze®, and EquiPlus Freeze® extenders revealed the same capacity of semen preservation in vitro and in vivo. Conclusion: HF-20 extender has the same quality as INRA Freeze® and EquiPlus Freeze® that can be considered as one of the best extenders for the semen cryopreservation in horses. In contrast, Tris extender needs some degree of improvement.

Semen cryopreservation protocols for wild avian species need to be optimised in order to achieve optimum post-thaw sperm quality and fertility. The present study was designed to evaluate the cryoprotective effect of different glycerol concentrations (11%, 15% and 20%) on post-thaw quality, recovery rates, absolute livability index and fertility of Indian Red Jungle Fowl (Gallus gallus murghi) semen. Semen was collected from eight mature cocks and cryopreserved for storage at −196 °C. Frozen semen was thawed at 37 °C for 30 s and assessed for motility, plasma membrane integrity, viability and acrosome integrity at 0, 2 and 4 h incubation at 37 °C. Percentages of motility, plasma membrane integrity, viability and acrosome integrity were recorded higher (P<0.05) post-thaw at 0, 2 and 4 h at 37 °C with 20% glycerol compared to 15% and 11% glycerol. Likewise, recovery rates (%) of aforementioned parameters after cryopreservation and absolute livability index were observed highest (P<0.05) with 20% glycerol. By comparing values of R2 after multivariate regression analysis, least negative effects of hours of incubation were observed on semen quality in extenders with 20% glycerol followed by 15% and 11% glycerol. The fertility outcomes (number of fertile eggs, fertility [%], number of hatched chicks, percent hatch and hatchability of fertilised eggs) were recorded higher (P<0.05) with 20% glycerol followed by 15% and 11% glycerol. It is concluded that the concentration of 20% glycerol gives the best cryoprotection for quality and fertility of Indian Red Jungle Fowl semen.

AbstractMaintenance of plasma membrane integrity is essential for normal cell viability and function. Thus, robust membrane repair mechanisms have evolved to counteract the eminent threat of a torn plasma membrane. Different repair mechanisms and the bio-physical parameters required for efficient repair are now emerging from different research groups. However, less is known about when these mechanisms come into play. This review focuses on the existence of membrane disruptions and repair mechanisms in both physiological and pathological conditions, and across multiple cell types, albeit to different degrees. Fundamentally, irrespective of the source of membrane disruption, aberrant calcium influx is the common stimulus that activates the membrane repair response. Inadequate repair responses can tip the balance between physiology and pathology, highlighting the significance of plasma membrane integrity. For example, an over-activated repair response can promote cancer invasion, while the inability to efficiently repair membrane can drive neurodegeneration and muscular dystrophies. The interdisciplinary view explored here emphasises the widespread potential of targeting plasma membrane repair mechanisms for therapeutic purposes.

AbstractPlasma membrane integrity is essential for cellular homeostasis. In vivo, cells experience plasma membrane damage from a multitude of stressors in the extra- and intra-cellular environment. To avoid lethal consequences, cells are equipped with repair pathways to restore membrane integrity. Here, we assess plasma membrane damage and repair from a whole-body perspective. We highlight the role of tissue-specific stressors in health and disease and examine membrane repair pathways across diverse cell types. Furthermore, we outline the impact of genetic and environmental factors on plasma membrane integrity and how these contribute to disease pathogenesis in different tissues.
