Split ejaculation study: semen parameters and calcium and magnesium in seminal plasma.
Article in Central European journal of urology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
objectivesMale infertility is on the rise. Artificial insemination is an option in many cases like oligozoospermia or oligoasthenozoospermia. Homologous insemination is helpful for some couples in whom sperm count is low. This study was aimed to understand the most suitable portion of split ejaculate for insemination and also the level of calcium and magnesium in each split. MATERIALS AND
methodsA total number of 31 normal and clinically healthy adults participated in this study. They were instructed to maintain abstinence for 2-5 days prior to sample collection in three splits. Each split was evaluated as if it were a whole sample, following WHO criteria. Seminal plasma was separated. Calcium and magnesium levels were measured in seminal plasma and spermatozoa of each split.
resultsThe split ejaculate study revealed that the first portion contained a higher number of spermatozoa with better motility than the 2nd and 3rd splits. Similarly, the level of calcium and magnesium in seminal plasma and spermatozoa was greater in the first split, followed by 2(nd) and 3(rd) splits.
conclusionThe presented split ejaculate study has shown the first ejaculate as superior in quality in terms of total sperm count and percentage of active motility. The first split of ejaculation is recommended for homologous artificial insemination in case of oligozoospermia and oligoasthenozoospermia. This study has also shown that a major portion of two important elements, calcium and magnesium, is contributed by the prostate gland.
