Testicular tissue bank: ten years of testicular tissue cryopreservation in Croatia.
Article in Croatian medical journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The Testicular Tissue Bank has been operating at the University Hospital Center (UHC) Zagreb since 2013. It aims to cryopreserve testicular tissue from patients with azoospermia. If spermatozoa are found in the collected tissue, a combined procedure known as testicular sperm extraction (TESE)/intracytoplasmic sperm injection (ICSI) is performed. During the last 10 years, our bank has deposited samples from 443 patients collected either by conventional TESE or microsurgical TESE procedure. Among them, 9% were from oncological patients whose samples were stored to preserve fertility. According to pathohistological analysis, 17% of patients were diagnosed with complete spermatogenesis or hypospermatogenesis, 11% with spermatogenic arrest, 48% with mixed atrophy of seminiferous tubules, and 24% with Sertoli cell-only phenotype or tubular fibrosis. Overall, the presence of testicular spermatozoa was found in 58% of patients, which makes them suitable for the ICSI procedure. In 21 out of 59 patients (36%) who underwent a salvage TESE, the outcome was different than that of the first spermatozoa retrieval attempt. Considering that the male factor is one of the leading causes of infertility, the results of Testicular Tissue Bank activity confirm its important role in improving the demographic picture of Croatia.
