We are sorry to hear of your husband’s infertility.
Although there is a specific concern about children being conceived during niddah, the laws of taharat hamishpachah apply irrespective of the possibility of conception. A woman who has uterine bleeding is considered niddah whether or not she might conceive.
Pregnant couples and couples using contraception still observe these laws; similarly, your observance of taharat hamishpachah is not affected by your husband’s condition. Every time you enter the niddah status through uterine bleeding, relations are prohibited and harchakot apply until you exit niddah through the taharah process culminating in mikveh immersion.
If you become interested in exploring your fertility options, we invite you to arrange a free consultation with a Yoetzet Halacha Fertility Counselor, details here.
