There are also sex-specific side effects of AAS. Development of breast tissue in males, a condition called gynecomastia (which is usually caused by high levels of circulating estradiol ), may arise because of increased conversion of testosterone to estradiol by the enzyme aromatase .  Reduced sexual function and temporary infertility can also occur in males.    Another male-specific side-effect that can occur is testicular atrophy , caused by the suppression of natural testosterone levels, which inhibits production of sperm (most of the mass of the testes is developing sperm). This side-effect is temporary; the size of the testicles usually returns to normal within a few weeks of discontinuing AAS use as normal production of sperm resumes. 
I feel this isn’t a good way of handling CSS. This method can fix a few inconsistencies in the declarations, like using a slightly off color, but that can be fixed using variables. I think that CSS repetition is a necessity, simply to make it easier to maintain. I mean if you have a button, you don’t necessarily want that linked to a content style simply because they have the same padding and margin. I feel that CSS should be seperated by intent and context of the element, not by its styles. By this and leveraging variables, you can have more maintainable code. You may argue that this would lead to bigger file sizes, and it does, in certain contexts. Let’s take yours. So I loaded up your files in three seperate tabs and compared them. Original, O-Formatted, and DRY. File sizes were as you said, but that isn’t interesting. What is, is how they were sent. You see, GZIP is a very nice compression format that browsers can handle. Turns out you are serving GZIP, so that makes it easier to test. Original was served in , O-Formatted was served in , and DRY was served in . Interesting how even though O-Formatted was a bigger file size, it had a smaller download than DRY. That is because GZIP really likes repetition. It is able to find these sorts of patterns and cut the download to what is necessary to recreate it. So why make it harder for maintenance, if a computer can just make use of these repetitions and optimize there.
