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

Male infertility contributes substantially to overall infertility, with temperature changes adversely affecting the sperm quality. During infertility treatments, the exposure of home-collected semen to extreme temperatures during transport deteriorates the semen parameters. This study investigates the effectiveness of thermal containers and insulation materials for preserving semen quality at low temperatures. Semen samples from 35 healthy male partners undergoing fertility treatments were analyzed. The samples were segregated in three groups and assessed: standard collection containers (Group A), thermal containers (Group B), and thermal containers with warming materials (Group C). Samples exposed to 4°C exhibited a notable decline in motility and forward motility over time, whereas groups B and C maintained these parameters better. Group C maintained the internal temperature at approximately 20°C for up to 90 min, reducing cold-induced deterioration. These findings demonstrate that cost-effective thermal retention methods can preserve semen quality during transport, and potentially improve the outcomes of intrauterine insemination and in vitro fertilization.
