There are no male ob nurses where I work. There is one male OB in a practice with 4 female OBs. There is one or two male family practice physicians who still have privileges for delivery, and there are probably 10 or 12 female GPs with privileges. I haven't worked on that floor for several years, so I don't have exact numbers for you.
we do not have any male OB RNs on our unit. Pedi has 1.
out of the three OB practices who deliver at our hospital, we only have 3 male OBs (a total of 10 female OBs between the three practices). The family practice who delivers has a few more more. And most of our residents are male.
No male RNs in Labor and Delivery, Postpartum, or the NICU where I work. About 50% of our OBs are male. We also have several male pediatric PAs who attend sections and any vag. delivery where there are/may be complications. The majority of our residents are females.
I work in London UK and there's a few of us male midwives around. My last unit had 5 but in new unit I'm only 1 of 2 so it does vary. Obstectricians tend to be about a 60/40 split in favour of the girls at lower grades (SHO) but by the time they get to consultant its back to about a 50/50 split.
