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

Infertility is increasingly recognized as being closely linked to obesity in humans. The successful production of fertile spermatozoa requires adequate spermatogenesis within the testis and proper spermatozoa maturation through the epididymis. This study aimed to evaluate the impact of body adiposity on male fertility, focusing on sperm parameters, epididymal sperm maturation, and sperm capacitation in Wistar rats. Male rats were randomized into three dietary groups over four weeks: a control group receiving less than 4% lard, regular chow, a 10% lard group, and a 60% lard group. Following dietary interventions, fertility tests were conducted across the groups. The epididymis was dissected into caput, corpus, and cauda regions to assess sperm concentration, vitality capacitation, carbohydrate distribution, tyrosine phosphorylation, and phosphatidylserine levels. Additionally, serum testosterone levels were measured to evaluate hormonal influences on fertility. The rats subjected to high-fat diets leading to overweight and obesity exhibited significant alterations in fertility. These changes were characterized by impaired epididymal sperm maturation, as evidenced by lower testosterone levels, decreased sperm viability, and capacitation. Furthermore, increased adiposity was associated with a lack of asymmetry in the plasma membrane, alteration in carbohydrate distribution, and changes in tyrosine phosphorylation. This study underscores the adverse effects of high-fat diets on male fertility, particularly through mechanisms affecting sperm maturation in the epididymis. The evidence suggests that obesity-induced alterations in sperm parameters and hormonal profiles may contribute to reduced fertility in male rats, which could have implications for understanding similar human processes.
