Abstract
Semen quality has a direct relation to male fertility. Whether sperm variables in humans have decreased over the last years is still uncertain, with some studies showing a decline and others reporting no changes. In this regard, previous research has suggested that lifestyle and environmental conditions may contribute to this variability, calling for regional studies. The present work is a retrospective, unicentric study that includes semen samples analyzed between 1997 and 2017 at the Parc Taulí Hospital (Barcelona metropolitan area). First, a multivariate analysis including the age as a confounding factor showed a statistically significant decrease in semen volume, pH, progressive motility, morphology and total motile sperm over time. Contrarily, no significant variation in sperm count or concentration was observed. Mean reductions per year were -0.02 mL for volume, -0.57% for progressively motile sperm and -0.72% for sperm with normal morphology. Interestingly, the average annual temperature registered by the Spanish Meteorology Agency negatively correlated to sperm morphology and sperm count (Rs = -0.642; p = 0.002 and Rs = -0.435; p = 0.049, respectively). In conclusion, the present study based on infertile patients from the Barcelona area found a decline in sperm motility and morphology, without effects on sperm count. Changes in temperature appeared to be associated to this decline, but further studies are needed to address the mechanisms linked to the observed variations.

Is seminal quality worsening? A 20-year experience in Córdoba, Argentina. J Assist Reprod Genet 2022; 39:1125-1134. [PMID: 35296953 PMCID: PMC9107558 DOI: 10.1007/s10815-022-02458-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 03/07/2022] [Indexed: 10/18/2022] Open
Abstract
PURPOSE To assess the possible variations in semen quality during the last 20 years in Córdoba, Argentina, and to identify possible causal lifestyle or genitourinary factors. METHODS Retrospective study of 23,130 patients attending an andrology laboratory. The 20-year period (2001-2020) was divided into four quinquenniums. Seminal parameters (sperm concentration, motility, morphology, viability, and membrane functional integrity) were classified as normal or abnormal according to WHO, and results were expressed as percentage of patients abnormal for each parameter per quinquennium. In addition, the percentage of patients per quinquennium exposed to the different risk factors (daily alcohol and/or tobacco consumption; occupational exposure to heat or toxics; history of parotitis or varicocele; and high body mass index, BMI) was reported. RESULTS Patients included in our study did not show impairment in seminal quality over time. Beyond a transient decrease in normozoospermia in the second and third quinquennium, possibly explained by a parallel increase in teratozoospermia, other important parameters of the spermogram did not change. In fact, abnormalities in sperm concentration (oligozoospermia), total sperm count, viability and response to hypoosmotic test showed a decreasing trend over time. On the other hand, parotitis, varicocele, morbid obesity and regular exposition to heat/toxics were the factors more frequently associated with semen abnormalities; the last two increased their frequency over the study period. CONCLUSION The population included in this study did not show a clear impairment in semen quality during the last 20 years. The decreasing patterns found were associated with high BMI and exposure to heat/toxics.

J Assist Reprod Genet 2018; 35:2201-2204. [PMID: 30328572 PMCID: PMC6289917 DOI: 10.1007/s10815-018-1330-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Accepted: 10/02/2018] [Indexed: 11/29/2022] Open
Abstract
PURPOSE A recent study suggested that ibuprofen may alter testicular physiology in a state of compensated hypogonadism, but only evaluated spermatogenic cells in a laboratory ex-vivo model with no significant effect, and found no significant change in follicle stimulating hormone (FSH) in men treated with ibuprofen. The study did not evaluate the impact of ibuprofen use on clinical semen parameters, which has not been assessed to date. The purpose of this study was to evaluate the impact of ibuprofen on semen parameters. METHODS In a retrospective chart review from October 2012 to February 2018, 64 men had semen analyses revealing leukocytospermia and were treated with a 3-week course of ibuprofen 600 mg every 8 hours (1800 mg per day) and had a repeat semen analyses 3 weeks later. RESULTS Of the 64 men diagnosed with leukocytospermia, 51 returned for post-treatment semen analyses. Parameters included semen volume, sperm concentration, motility, TMC, and forward progression. Morphology was excluded as it could not be standardized between assessments with strict Kruger criteria versus WHO fourth edition criteria depending on the lab in which it was performed. The mean age of these men was 35 (SD 4.6). There was no difference in mean abstinence intervals prior to semen analyses for the pre-treatment and post-treatment data. There was no significant difference in pre-treatment and post-treatment semen volumes, sperm concentrations, motility, TMC, or forward progression. CONCLUSIONS Among men with leukocytospermia, the treatment with a 3-week course of ibuprofen at 1800 mg per day did not demonstrate a significant adverse impact on semen volume, sperm concentration, motility, TMC, or forward progressive motility when compared to pre-treatment semen analyses parameters.
