Sperm count affects cumulative birth rate of assisted reproduction cycles in relation to ovarian response.
Article in Journal of assisted reproduction and genetics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeTo explore the possible influence of sperm quality, as assessed by prewash total sperm count (TSC), on cumulative success rates in assisted reproduction cycles.
methodsRetrospective study carried out in private IVF centre. Seven hundred sixty-five couples undergoing complete ICSI cycles, i.e. whose all embryos were transferred or disposed of. Couples were characterised by male infertility and female age younger than 36 years. Couples with a combination of female and male infertility factors were excluded. The primary outcome measure was cumulative live birth rate. Secondary outcomes were cumulative pregnancy and miscarriage rates. No specific interventions were made.
resultsHigher TSC values have a positive impact on cumulative success rates in cycles characterised by few retrieved oocytes (1 to 5), while does not influence the outcome of cycles with a normal (6 to 10) or high (> 10) number of retrieved oocytes.
conclusionsThe study highlights the importance of sperm quality for the efficacy of assisted reproduction treatments. This influence may remain relatively cryptic in association with normal or high ovarian response, but emerge decisively in cases of reduced ovarian response, suggesting a relationship between ovarian response and oocyte ability to compensate for paternal-derived deficiencies.
