Seminal profile of 23,504 patients over the years: 7 years of experience

Abstract

ObjectiveTo evaluate the behavior of seminal parameters over the years - 2010 to May 2017.MethodsA retrospective study, carried out from January 2010 to May 2017, covering men who underwent sperm examination. Seminal parameters (volume, sperm concentration, motility, morphology, age and duration of infertility in years) of 23,504 men were evaluated. The groups were compared to each other to check whether there were changes to the seminal parameters in that period.ResultsThere was no change over the years considering the time of infertility, in an average of 3.78 years. The mean age of the patients was 36.53 years, with a trend of increase in 0.2 years. In relation to the volume of semen samples, the mean value was 3.29mL, with a decrease trend in 0.05mL. As for sperm concentration, the average was 34.37 million/mL, with a decrease trend of 1.0 million/mL. Progressive sperm motility showed an average of 47.27% and there was a decrease trend of 0.67%. Finally, sperm morphology presented an average of 2.79% of normal spermatozoa, with a decrease trend of 0.33%.ConclusionIt can be noted that over the years, the sperm quality of men looking for assisted reproduction clinics has tended to decrease in macroscopic and microscopic parameters (volume, sperm concentration, motility and morphology).

Oligoasthenozoospermic and Normozoospermic Indian Males Yielded Similar Fertilization Capability by Intracytoplasmic Sperm Injection

“…Furthermore, a reduction in sperm motility was observed from about 26% to 8.5% over a period of time (Geoffroy-Siraudin et al, 2012;Oliveira, et al, 2014). Sperm motility was lower than that reported in men from different countries like Brazilian sub-fertile men (Nogueira et al, 2018), and ejaculates of Italian (Manna et al, 2020) and Indian males (Mukhopadhyay et al, 2010), but was similar to the results reported in India (Camila et al, 2018). Such differences could be attributed to racial, geographical, cultural, environmental, genetic, hormonal, nutritional, or lifestyle variations.…”

Spatiotemporal trends in human semen quality

“…Also in Sao Paolo, semen data from 23,504 infertile men were evaluated over 7.5 years from 2010 to 2017 according to WHO 2010 guidelines 17 , 92 . A decreasing trend of 0.05 ml in seminal volume was observed over the period, alongside a tendency towards reduction in sperm concentration by 1 × 10 6 /ml over the 7.5 years (mean of 34.3 × 10 6 /ml).…”

Semen Quality in the General Population of Bulgaria

“…This is due to the fact that various causes of infertility can be bypassed by the use of ART; however frequently the primary condition remains untreated. While female infertility has drawn more attention, it is proposed that 1 in 20 men are infertile on worldwide scale [1]. Moreover, the cause of infertility in about 20% -40% of infertile couples is attributed to the male partner [2].…”
