Background: The most common chromosomal abnormality due to non-obstructive azoospermia (NOA) is Klinefelter syndrome (KS) which occurs in 1-1.72 out of 500-1000 male infants. The probability of retrieving sperm as the outcome could be asymmetrically different between patients with and without KS, therefore logistic regression analysis is not a well-qualified test for this type of data.

Effect of melatonin in the prevention of postoperative pericardial adhesion formation.

To evaluate the efficacy of melatonin in preventing postoperative pericardial adhesions, 12 single breed dogs were randomized equally into experimental (melatonin) and control groups. After ketamine anesthesia, a vertical midsternal incision was done and the parietal pericardium of the inferior site of the heart was opened vertically. To promote adhesion formation, abrasions were created on both parietal and visceral pericardial surfaces in an area of 2 cm2 with two vertically reciprocal movements of dry gauze.
