The fertility preservation decision-making and testicular sperm retrieval outcome in older adolescents with nonmosaic Klinefelter syndrome and azoospermia.
Review in Journal of the Chinese Medical Association : JCMA, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThis study aims to analyze the fertility preservation decision-making and the sperm retrieval rate (SRR) in older adolescents (age 15-19 years) with nonmosaic Klinefelter syndrome (KS) and azoospermia in a male reproductive clinic, and to determine the accumulated SRR in older adolescents by literature review.
methodsOlder adolescents with nonmosaic KS and azoospermia referred for hypogonadism and fertility concerns were enrolled. Reproductive counseling and fertility preservation options were offered to patients/parents. The acceptability and the reasons affecting the reproductive decision-making were analyzed. Patients/parents who agreed on fertility preservation received microdissection testicular sperm extraction (mTESE) and cryopreservation. A comprehensive literature review regarding the SRRs in older adolescents with KS was conducted.
resultsA total of eight older adolescents were enrolled. After fertility preservation counseling, three patients/parents (37.5%) agreed to receive mTESE, and spermatozoa were successfully retrieved in two. "Lack of interest" and "inconsistent sperm retrieval result" were the main reasons for refusal. A total of 89 older adolescents from nine articles, and ours were collected for SRR analysis. Most of the reports had a limited number of cases, and none of them described the acceptance rate of sperm retrieval in adolescents. Forty-three out of 89 older adolescents (48.3%) had successful sperm retrieval, and there was no significant difference in the SRR between the mTESE and conventional TESE.
conclusionSuccessful testicular sperm retrieval in older adolescents with KS is not superior to those reported in adults. Adolescents and their parents should undergo a detailed reproductive consultation process and shared decision-making discussion before considering testicular sperm retrieval.
