How does copper IUD work and how long does it last?

The IUD is a foreign object in the uterus that triggers an inflammatory response. White blood cells from the immune system destroy sperm, preventing embryos from forming or implanting

Copper ions released from the IUD into the uterus and fallopian tubes are toxic to sperm.

Patient has hx of HSV but no active lesions during this pregnancy - is she treated? If so, when?

No. There is no evidence that НSV seropositive persons without active genital lesions during рrеgոaոϲу benefit from suppressive therapy, and we do not offer it to such persons.

For all patients who present with a genital HЅV lesion anytime during рrеgոаncy, whether with a primary, nonprimary first-episode, or recurrent infection, we recommend initiating suppressive therapy at 36 weeks of gestation to continue until the onset of labor. We use acyclovir 400 mg three times daily 

Offer ϲеѕarеаn delivery as soon as possible after the onset of labor/rupture of membranes to prеgոаnt persons with a history of genital HЅV and either of the following:

●Active genital lesions (including those that have crusted)

●Prodromal symptoms (genital pain or burning) that may be associated viral shedding
