Outcomes of microdissection testicular sperm extraction in azoospermic men following chemotherapy: A cross-sectional study.
Article in International journal of reproductive biomedicine, 2026. 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
Background: The use of chemotherapy agents can increase the likelihood of azoospermia in men. Today, the application of micro-dissection testicular sperm extraction (micro-TESE) and subsequent intracytoplasmic sperm injection (ICSI) is recommended for sperm retrieval in such affected men. Objective: We aimed to report our experiences with the success rate of the protocol of micro-TESE in maintaining sperm restoration in men undergoing chemotherapy protocols for different cancers. Materials and Methods: In this cross-sectional study, data of 33 men who were scheduled for micro-TESE and subsequently ICSI due to non-obstructive azoospermia (following the use of chemotherapy agents because of different types of malignancies) and were referred to Royan Institute for Reproductive Biomedicine, Tehran, Iran from 2010-2023 were extracted from their medical records. At the end of the study, we measured the success rate of sperm retrieval using micro-TESE in men with chemotherapy-related non-obstructive azoospermia. Results: Adequate amounts of spermatozoa were successfully retrieved for cryopreservation and subsequent ICSI in 16 out of 33 cases, resulting in a sperm retrieval rate of 48.5%. None of the baseline parameters, including individuals' age, time and duration of chemotherapy, type of cancer, history of smoking or alcohol use, or baseline hormonal states, might affect the rate of sperm retrieval. Conclusion: Applying micro-TESE can retrieve sperm exposed to chemotherapy protocols. Also, it can be useful for reducing the likelihood of chemotherapy-related azoospermia.
