There can be several causes for retrograde ejaculation. This can include the side effects of certain medications, diabetes, or possible prostate or urethral injury, surgeries or masses.
It may be possible that the cyst may be leading to some of your symptoms.
You can consider a cystoscopy to evaluate the lower GU tract or a transrectal ultrasound to image the prostate.
Going over any medications that you may be taking may help reveal a potential cause for your symptoms.
You can discuss these options with your urologist, or consider this with another urological opinion.
Followup with your personal physician is essential.
