A 67-year-old client reports to her healthcare provider that she is having difficulty during intercourse, causing her pain and d
Yakvenalex [24]

The cause of the client’s pain must be because of atrophy of bulbouretheral glands. The bulbourethral glands are the one responsible for secreting a substance which we call alakaline, in order to be able to provide neutralization in the acidic environment in a person’s urethra. The bulbourethral glands are also responsible in having to provide lubrication to a person when having to do a sexual intercourse. If it gradually declines in its effectiveness, during sexual intercourse, it would likely cause the person to have pain and have difficulty in having to do an intimacy with the person’s partner as atrophy may be present in the person’s bulbourethral gland.
