1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background: As the Omicron variant became the dominant coronavirus disease 2019 (COVID-19) strain and the threat to human health decreased, the impact of COVID-19 on male reproductive health and semen quality may have changed. In this prospective observational study, we aimed to investigate the changes in semen quality and sexual function before and after the Omicron variant infection by self-controlled study and to explore the influence of Omicron variant infection on male reproductive health. Methods: We recruited 373 participants who provided semen samples before their first COVID-19 infection. During the subsequent follow-up, only 154 participants provided the second semen samples, 11 of whom were not infected with COVID-19. Sperm quality was assessed approximately 45 and 90 days after COVID-19, as well as before infection. Results: Semen parameters, including total sperm count, total forward sperm, progressive motility, and sperm concentration, significantly declined 45 days after COVID-19 infection. At 90 days after infection, the total sperm count, total forward sperm, and sperm concentration gradually increased to pre-infection levels. Participants who experienced fever showed worse semen quality in terms of total forward sperm, sperm concentration, and sperm progressive rate. However, this phenomenon was not observed in the other group infected with COVID-19 without fever or not infected. In addition, 49 (34.3%) of 143 persons confirmed that the COVID-19 infection resulted in changes in sexual function, with an increase in premature ejaculation diagnostic tool (PEDT) scores. Conclusions: The results of our self-controlled study indicate that COVID-19 is associated with impaired semen quality early after disease onset. After 1-2 spermatogenesis cycles, the semen quality gradually recovers from the infection. These findings are beneficial for better understanding the COVID-19-associated sequelae, which are fundamental for semen collection during assisted reproduction.
