Success rate of microsurgical multiple testicular sperm extraction and sperm presence in the ejaculate in korean men with y chromosome microdeletions.
Article in Korean journal of urology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers.
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
purposeWe assessed the frequency of azoospermia factor a (AZFa), AZFb, and AZFc deletions and examined correlations between the deletion sites and the success rates of sperm presence within the ejaculate and surgical sperm retrieval in Korean men. MATERIALS AND
methodsA total of 1,919 azoospermic and severely oligozoospermic men were assessed for Y chromosome microdeletions. Among them, 168 men with AZF deletions were identified and their medical records were reviewed.
resultsOf the total 168 men with AZF deletions, there were 13 with AZFa, 10 with AZFb, 95 with AZFc, 37 with AZFbc, and 13 with AZFabc deletions. Of the 95 men with isolated AZFc deletion, 51 had the presence of sperm in the ejaculate. Of the infertile men with any other deletion, however, only two patients (one man with AZFb deletion and another with AZFbc deletion) showed the presence of sperm in the ejaculate. The success rates for surgical sperm retrieval were 7.1% (1/14) in men with AZFbc deletion and 54.8% (17/31) in the isolated AZFc deletion group. No sperm was obtained from the patients with AZFa or AZFb deletions who underwent microsurgical sperm retrieval. In the isolated AZFc deletion group, there were significant differences between azoospermic and severely oligozoospermic patients in terms of testicular volume and serum levels of follicle-stimulating hormone and luteinizing hormone, whereas no significant differences were found when the group was divided by surgical sperm retrieval outcomes.
conclusionsDeletions of the AZFa and AZFb regions are associated with severe spermatogenetic impairment. However, more than half of men with an AZFc deletion had sperm within the ejaculate or testis for in vitro fertilization with intracytoplasmic sperm injection.
