Home -> Masturbation related news -> Masturbation Vs. Intercourse on Programs of Assisted Reproduction

Japan - November 18th, 2005: Researches are being made in order to improve the quality of semen samples of infertile men engaged in programs of assisted reproduction. The quality of the semen collected for such procedure is essential to the success of the fecundation process.

Surprisingly, results found that the semen collected through masturbation and during intercourse (using a semen collection device) were slightly different in what refers to chemical biophysical and endocrinological parameters. A group of 38 infertile men were selected for the experience, collecting 6 semen samples from different days through regular masturbation. Next, 6 more samples were collected from the same men during sexual intercourse, also in different days.

Parameters such sperm mobility, total sperm count and the percentage of morphologically normal sperm showed important higher differences in the samples collected through intercourse of all men tested. Such differences cannot be attributed to hormonal changes happening during intercourse, o­nce hormonal levels were practically the same o­n both situations.
