Cryopreservation media differentially affect sperm motility, morphology and DNA integrity
Andrology
|August 15, 2018
Summary
Cryopreservation media negatively impact sperm quality. Cryomedium A showed the lowest survival rate and highest DNA damage in infertile men, suggesting careful selection is crucial for fertility preservation.
Area of Science:
- Reproductive biology
- Andrology
- Cryobiology
Background:
- Sperm cryopreservation is vital for male fertility preservation.
- Standardized cryopreservation media vary in composition, lacking comparative data for optimization.
- This study addresses the need for comparative analysis of commercially available sperm cryopreservation media.
Purpose of the Study:
- To compare five commercial sperm cryopreservation media.
- To evaluate the impact of these media on sperm motility, morphology, and DNA integrity.
- To identify optimal media for sperm cryopreservation in infertile men.
Main Methods:
- Collected 100 semen samples from fertile and infertile men.
- Assessed sperm motility, morphology, and DNA fragmentation index (DFI) before and after cryopreservation.
- Cryopreserved samples using five different media (A-E) and re-evaluated parameters post-thaw.
Main Results:
- All tested media negatively affected sperm motility and morphology.
- Cryomedium A exhibited significantly lower cryosurvival rates in infertile men (p < 0.001).
- Cryomedium E showed increased coiled tail sperm (p < 0.05 vs A, p < 0.001 vs B), and all media increased DFI post-thaw.
Conclusions:
- Sperm cryopreservation recovery rates remain a challenge for infertile men.
- The choice of cryopreservation medium significantly impacts post-thaw sperm quality.
- Judicious selection of cryopreservation media is essential for successful male fertility preservation.

1.5K
Op-amp circuits have significant applications in various fields, including automotive engineering. One such application is cruise control systems in cars, where op-amp circuits are integral for maintaining a constant speed. In these systems, op-amps function as both integrators and differentiators.
An integrator within an op-amp circuit produces an output directly proportional to the integral of the input signal. This is achieved by replacing the feedback resistor in a typical inverting...

01:24Role of Affect in Interpersonal Attraction
232
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.

01:29The Influence of Affect on Cognition
296
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

01:29The Influence of Cognition on Affect
221
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
