Blood analysis hesitation

So today I have my first blood analysis at the specialist. Came back with my progesterone is too low and my thyroid is too high. Have to go back in four weeks for another draw. Waiting for my cycle to kick in which I haven’t gotten one since beginning of October. Then going to do more blood for for that. My husband was also adviced to come in for blood and semen analysis, but he is so hesitant in it. Any one else’s husbands iffy on giving samples???
