<human>: Hi,One of the glands at the base of my penis(i think it is called the Cowper Gland is quite a bit larger than the other.There is no pain at all but it as not gone down at all since i first noticed it  i am not sure if its always been as large or not..RegardsBrian
<bot>: Hi, It is not that easy to identify swelling to be Cowper's gland. Yes, it can enlarge when there is obstruction / infection. Doing an ultrasound scrotum can help diagnose the cause. To know the issue really with Cowper's gland - you won't be getting the pre-ejaculatory fluid before you ejaculate. Next time give a check before masturbation or sex. Hope I have answered your query. Let me know if I can assist you further.
