Sperm donors
It is always worth considering whether you should buy more than one unit in advance and store it in a sperm storage here at the clinic.
By storing units here at the clinic, you make sure that there will be units from the same donor available for several treatments. In case you want siblings from the same donor in the future, it is also a good idea to consider a sperm storage, as he could be out of stock or inactive by that time.
The Diers Clinic can set up a sperm storage for you.
