Neonatal Clomipramine Exposure Disrupts Epididymal Serotonin Signaling and Programs Sperm Dysfunction in Adult Rats.

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.
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
Studies of adult depressed patients report that selective serotonin (5-HT) reuptake inhibitors (SSRIs) like clomipramine (CMI) have secondary effects on sperm quality. The epididymis possesses an autonomous serotonergic system critical for sperm maturation, whose establishment during neonatal development remains unexplored as a target for SSRI programming. We hypothesized that neonatal CMI exposure would disrupt the developing epididymal 5-HT system, leading to permanent sperm dysfunction. CMI (30 mg/kg s.c.) was administered to male rats between postnatal days 8-21. At 3 months, sperm from the epididymal cauda was evaluated, and 5-HT levels were measured in the testis, caput, and cauda epididymis. Our novel findings demonstrate that neonatal CMI exposure induces region-specific, long-term alterations in epididymal 5-HT levels (decreased in caput, increased in cauda) without affecting testicular 5-HT. This reprogramming of the local serotonergic milieu was associated with reduced sperm concentration, viability, normal morphology, and motility, alongside increased mitochondrial activity and reactive oxygen species. This study reveals, for the first time, that the epididymal serotonergic system is a key target for neonatal SSRI programming, providing a mechanistic link (altered 5-HT homeostasis) between early-life exposure and persistent sperm defects in adulthood.
