Primary testicular failure is a broad diagnosis but in some cases even men with primary testicular can bear natural children.
Today micro TESE and ICSI have the potential to produce children. Though success rate may be very low.
These are expensive surgeries and adequate training is required.
You will also need a fnac and genetic testing to rule out mutations.
Next Steps
See an Andrologist or male infertility specialist
