The following is a summary of the processes and costs to be aware of if you wish to consider freezing your reproductive cells (sperm or eggs) prior to starting hormone therapy or having gender-affirming surgery. If you have already started on hormone therapy, it may be possible to take a break.
After a three-month break from feminizing hormones, sperm should be back to 80% of previous levels. By six months sperm should be 100%. If fertility has not resumed after six months, it is not likely to return.
The processing fee for sperm is about $200. The storage costs are about $200 per year.
There is no set timeline for how long you can be on testosterone and still be able to take a break and produce eggs. Generally, the younger you are and the less time you have been on testosterone the better the outcomes. If you have been on testosterone for 10 years or more, or are over age 40, you are less likely to produce viable eggs.
The process for harvesting eggs is more complicated than for collecting sperm. You would take a break from hormones, then take shots twice a day for 10 to 14 days to stimulate multiple eggs. During a short office visit at a fertility clinic, a probe would be used to harvest the eggs from the vagina. (You would be sedated during the procedure.)
The cost for the procedure is about $8,000, plus $3,000 for medications.
Once the eggs are removed, they are frozen and can remain frozen for years, until you or your partner is ready to try to get pregnant. The fertilization and implantation process costs about $3,000 for each attempt.
