Why do men opt for Semen Freezing?
Sperm cryopreservation is a suitable method for men in following cases:-
- It is for individuals, who wish to store their sperm in a sperm bank.
- For men with or planned oncological treatment.
- During IVF/IUI treatments: A fresh semen sample in most situations will give the best results for IUI and IVF treatments, however, sometimes freezing of a ‘back up’ semen sample may be advised. This may include situations where there is difficulty producing a sample on the day, where for employment reasons the male partner is not nearby, or in situations where there is declining semen quality.
- When prostate surgery or vasectomy is planned.
