Tying your tubes doesnt stop your period just stops you from concieving. You are able to untie your tubes, but at a great and lengthy price and toll and its 100% guarentee. I think you have to have a medical condition to have this procedure done without having children
You will still have periods whether or not you tie your tubes. If that is the reason you are considering doing it, please reconsider, because your periods will not be affected. (Look up a biological drawing of the relationship of the uterus to the Fallopian tubes. You can see that the period, which originates in the uterus and goes downward, has nothing to do with the Fallopian tubes.)
Also, to "untie" the tubes after ligation is a painful and expensive operation, not covered by health insurance. Women wanting this must pony up thousands of dollars out of pocket, and it is not guaranteed to work.
Finally, the egg freezing process is in its infancy, not always effective. (Embryos are regularly frozen and thawed, but egg freezing is new and not yet widely done or reliably successful.)
