Then we have the female virilization effects; virilization referring to the promotion of masculine traits in women; such effects can include body-hair growth, a deepening of the vocal chords and clitoral enlargement. For this reason, staying in the time frame of use mentioned in the benefits section is extremely important, and low doses should be used as well. If you do this, most women will be fine, but if virilization symptoms begin to show for any reason all hope is not lost. If symptoms begin to show, you should discontinue use at their onset, and if you do they will fade away rapidly. If they are ignored, this is where a problem will occur, and you may be stuck with them for the rest of your life.
