The purpose of this thread is to collect info on the subject and eventually turn it into an article. In this thread I would like to see how people have treated their drakes and what their outcomes were. I would also like to see links to treatments from credible sources. "Prolapsed Phallus Penis Prolapse Prolapsed phallus can sometimes occur in male ducks and can be trauma-induced or a clinical sign related to venereal disease. A prolapsed phallus is described as a condition in which a male duck's phallus (penis) remains outside of the body and is unable to retract back inside the body. The longer the phallus remains outside of the duck's body, the greater the risk of secondary bacterial contamination and damage to this important body part. When the phallus is outside of the body, it runs the risk of becoming enlarged and swollen, dry and ulcerating, and necrotic during advanced stages. The duck is usually acting abnormal and may appear depressed, isolate themselves, and show no desire to eat, mate, or socialize with other ducks. Prolapsed phallus is also a clinical sign that is often seen in ducks with duck plague."

Vaseline may be used externally only. It may cause infection due to the amount of petroleum and oil it contains. These products are not water soluble because they are not water-rrbased. As a result, your body may have a hard time getting rid of the petroleum jelly, which may lead to infection such as yeast infection. When used during sexual intercourse, Vaseline may cause condoms to break." From here: https://www.leaf.tv/articles/why-is-vaseline-not-for-internal-use/ "Various studies have linked petroleum jelly with the growth of yeast which causes severe infections. A link between this product to bacterial vaginosis and pelvic inflammatory disease has also been established, rendering it unsuitable. For this reason, experts recommend the use of alternative lubricants to avoid getting such diseases."
