spinnbarkeit

[spin′bärkīt, shpin′-]

Etymology: Ger, threadability

the clear slippery elastic consistency characteristic of cervical mucus during ovulation. The consistency is that of an uncooked egg white, and it is a valuable sign of the peak fertile period in a woman's menstrual cycle. Observation of spinnbarkeit is useful in natural methods of family planning, in the clinical evaluation of infertility, and in discovering the optimal time for artificial insemination. Spinnbarkeit may be evaluated by the length to which a string of mucus can be drawn between the fingers before breaking. See also ovulation method of family planning.

spinnbarkeit [spin´bahr-kīt] (Ger.)

the formation of a thread by mucus from the cervix uteri when spread onto a glass slide and drawn out by a coverglass; the time at which it can be drawn to the maximum length usually precedes or coincides with the time of ovulation.

Cervical mucus changes throughout the menstrual cycle. Spinnbarkeit describes how much mucus can be stretched between two fingers or between a microscope slide and coverslip. From McKinney et al., 2000.
