If the subject is going to be care of the intact penis, you have a chance to educate about the anatomy, and development, and hands off care of the intact penis (i.e. the importance of not retracting, and that the boy should be the first to retract). Make sure your talk about the foreskin as "normal," and "natural," and refer to it as an "intact" rather than an "uncircumcised" penis - all of this emphasizes that the foreskin is a NORMAL part of the body. WHen you write about the development (tight, fused foreskin is normal in childhood) you can include info on some of the protective functions of the foreskin (protects from abrasion, irritation, keratinization; and designed to keep out contaminants by sphincter action and regular flushing outward with urine, which is sterile as it leaves the body). You can point out how the foreskin is PERFECTLY DESIGNED. Also talk about how EASY it is to take care of (avoid scary associations with disease, claims that circed penises are easier, or admonitions that intact boys have to pay much closer attention to penile care). You can specifically state that the belief that intact penis is hard to take care of is a MYTH. Make sure you include education about NEVER FORCIBLY RETRACTING, and list some of the harms that can happen when the natural protective covering of the glans is disturbed prematurely.
Also in re: circed penises, you can make the comparison that with the loss of the foreskin parents will over the early years of life need to watch out for meatal stenosis which is a result of irritation and inflammation due to exposure of the urinary meatus (7-10% of circumcised boys, doesn't happen in intact). Also in re: the circed penis, parents need to be told about the risk of adhesions in 15-30% of circed boys where the raw surfaces of the cut foreskin can grow back onto the raw surface of the glans where the foreskin was ripped away (a way to educate about some of the realities of the procedure itself). They need to be told that this can lead to inflammation and difficulty cleaning in pockets or tunnels where the adhesion has occurred (debunks the myth that circed is easier to clean - see Van Howe's article on how penile inflammation is more prevalent in circed than intact. http://www.ncbi.nlm.nih.gov/pubmed/17475991
). They can be told that it has been suggested that adhesions can be prevented by pulling back the foreskin remnant regularly with diapers changes and applying vaseline underneath for the first few years of life (again, debunks the hygiene myths) http://www.cirp.org/library/complications/gracely1/
This is not an exhaustive list, just ideas off the top of my head. Certainly there's other basics of what to do, what to look for, e.g. in the case of the circed penis, that can highlight some of the unpleasant realities of the results of circumcision - observing for infection, bleeding; dealing with post-circ pain; using gauze and vaseline to prevent sticking and painful rubbing in the diaper; what to do if the dressing gets embedded in the wound; observing for slippage of the Plastibell ring; making sure the baby is peeing regularly.
Nurses are in a very important position to educate not only parents but their colleagues as well. Brava to you for doing your part to shift the knowledge base and the culture among the students and teachers you are in with. BTW, most of the medical/nursing lit on care of the intact penis is not very good. E.g. there is often bad info about the true age range at full retractability, which can lead to bad advice and improper handling of the foreskin.Feel free to PM me if you want to talk more on these ideas.
