At 46, you are obviously aware that conception will be difficult, if not impossible.
IVF is the only way ahead for you.
Your partner's semen analysis
is essential due to the testicular injury
Also, you can assess your egg forming capacity by testing your ovarian reserve
This is done by estimating AFC ( antral follicular count ) on ultrasound, measuring hormones like AMH ( anti mullerian hormone
) and FSH and LH on day 2.
This would tell you if your own eggs can be used for IVF
Your endometrial status needs to assessed for IVF also.
Please consult a reputed Infertility
