Title

SEMINAL CAPACITATION TECHNIQUES FOR INTRACYTOPLASMIC SPERM INJECTION BASED ON BHCG RESULTS IN THE YEAR 2021: A RETROSPECTIVE COHORT STUDY

Objective

Analyze the seminal capacitation techniques used for intracytoplasmic sperm injection in 2021 and compare them with the BHCG results.

Methods

Retrospective cohort study in which 503 BHCG results of patients who underwent Intracytoplasmic Sperm Injection (ICSI) at the IVI Salvador clinic during the period from January to December 2021 were analyzed, relating them to their respective seminal capacitation techniques. The patients were separated according to the chosen sperm selection technique and the results were divided into positive and negative. The methods considered were Discontinuous Density Gradient, Swim up and Simple Wash.

Results

In the 92 patients in whom the seminal capacitation technique was the Density Discontinuous Gradient, 54.35% (50) of the results were positive, and 45.65% (42) were negative. In 298 patients whose chosen technique was Swim up, 59.73% (178) of the cases developed a positive result, while 40.27% (120) had a negative result. When we talk about the Simple Wash technique, performed on 113 patients, 57.85% (63) of the patients had a positive result, while 42.14% (50) had a negative result.

Conclusion

Based on the study's results, it is possible to conclude that, in the year 2021, the sperm capacitation techniques selected for intracytoplasmic sperm injection (ICSI) performed at the IVI Salvador clinic obtained positive results in different proportions. Therefore, no significant difference demonstrates the influence of seminal capacitation techniques on BHCG results. However, we emphasize that the analysis was performed on a heterogeneous population sample, where the results cannot be applied to the general population. It is also important to highlight that the choice of sperm selection technique must be personalized, taking into account the specific characteristics of the couple, thus making individual cases to obtain better results.
