Expressive Writing as a Therapeutic Intervention in Male Infertility

Expressive writing is a therapeutic intervention designed by the psychologist James W. Pennebaker. Individuals write on three days for about 20 minutes about particularly stressful experiences in their life. Several studies showed that expressive writing can have beneficial effects on the frequency of health care utilization and well-being. Particularly in patients with rheumatism, kidney cancer and posttraumatic stress disorder expressive writing showed an positive effect on subjective well-being. Furthermore, in several studies expressive writing showed a positive effect on immune parameters.

As many studies suggest an important negative effect of stress on well-being and sperm parameters in male infertility, we want to investigate the effect of expressive writing in male infertility.The expressive writing condition is compared to a non emotional writing condition, in which individuals write about mainly non emotional topics such as time management. In this randomized-controlled trial subjects were allocated sequentially by block wise randomization (block size of 4). For randomization a computer generated random list was used. The allocation was concealed in a series of numbered sealed envelopes. The envelope was opened immediately before the first writing session.
