Lots of proteins But in one group of primates at least, the byproducts of the males' favourite hand exercise are now being put to good scientific use, while helping the primates at the same time. During the course of her research, Thomsen witnessed macaques, er, taking matters into their own hands hundreds of times. It sounds like a pretty unusual way to spend your time, but those hours yielded some very useful results. In , Thomsen's hard work laid the foundation for demonstrating a non-invasive method of collecting semen from masturbating macaques.

    In clinical programs of assisted reproduction involving infertile males, it is essential to obtain semen of maximum quality. To evaluate ways of achieving this objective, and to assess the fertilizing capacity of the sperm, six semen samples were collected from each of 38 infertile men via masturbation. Six more samples were then collected from each man at sexual intercourse using a semen collection device SCD. We confirmed that the volume of seminal plasma, total sperm count, sperm motility, and percentage of morphologically normal spermatozoa were significantly higher in samples collected at intercourse than masturbation, as reported previously. In addition, the markers of the secretory function of the prostate and the outcome of sperm function tests hypoosmotic swelling test, acrosin assay, and sperm penetration assay were significantly higher for the samples collected at intercourse.
