Abstract: The present invention relates generally to pharmaceutical compositions comprising esterified estrogens, methyltestosterone and one or more pharmaceutical excipients. Methods for preparing and using such compositions are also provided.

Abstract: An interlink for connecting hydrophone elements that allows a single sens fiber to transition from a first hydrophone element, across the interlink, to a second hydrophone element, while providing a secure connection between hydrophone elements without the disadvantages of mechanical resonances produced by a rigid interlink material. The interlink has a first end connected to a first hydrophone element, and a second end connected to a second hydrophone element. The interlink may be composed entirely of open cell foam, or a more rigid structure that is covered by open cell foam. Sensing fiber transitions from a first hydrophone element, onto the foam interlink, and thence onto a second hydrophone element, with only a change in winding angle. The sensing fiber is not susceptible to a rigid interlink structure and undesirable mechanical resonances.
