Donor sperm
Sperm provided by a screened donor for use in fertility treatment.
In plain English
This is sperm from someone else, used when there's no viable sperm from a partner or when treating without a male partner.
Why it matters
It's used in IUI or IVF when male infertility, absence of a partner, or genetic risk makes it the chosen route.
