Keep in mind that homeopathy was invented when standard treatments included blood letting, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;drugs made with mercury and arsenic, and natural remedies made with nightshade and hemlock. So &lt;/ins&gt;doing effectively nothing like homeopathy had better results than &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;many &lt;/ins&gt;other treatments of the time.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Since the average ejaculation contains 200 to 500 million sperm cells, this means the solution Cueball is holding has a 3.5x10&amp;lt;sup&amp;gt;-20&amp;lt;/sup&amp;gt;% chance of containing even a single sperm cell. Clearly, [[Megan]] will not be getting pregnant from this, so she and Cueball will not be passing on their genes, which is why the comic states that the belief in homeopathy is not selected for.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;Here we find [[Cueball]], a firm believer in homeopathy, applying the idea to fertility by diluting his semen. 30X means that the semen has been diluted with water at a 1:10 ratio 30 times, so the solution contains 1 part semen to one-nonillion (1,000,000,000,000,000,000,000,000,000,000) parts water.
