22 physician-providers who serve natural family planning (NFP) programs, mostly in the private sector, gathered to formulate a standard terminology for the field. The Billings and sympto-thermal methods are the 2 methods taught by this group. The sypto-thermal method helps a woman predict ovulation by detecting changes in her cervical mucus and in the cervix itself. Ovulation is confirmed by...

The mucus filling the human cervical opening blocks the entry to the uterus, but this has to be relative and allow for the sperm to penetrate at ovulation. We studied this mucus, its content of proteins and mucins, and the mucin O-glycosylation in cervical secretions before, during, and after ovulation. Cervical mucosal secretions from 12 subjects were collected, reduced-alkylated, separated wi...

Plunging or cervical ranula is a mucus extravasation pseudocyst arising from the sublingual gland that is located below the mylohyoid muscle. Clinically, if large enough, cervical ranulas can affect swallowing, speech, chewing, and even breathing. The acute presentation of ranulas, which are clinically known as slow-growing, painless masses, is rare. In this study, we present a case of cervical...

The use of the progestogen-only pill as a 'pre-coital contraceptive' was tested by in vitro studies of sperm-mucus interaction. The results suggest that a single tablet of levonorgestrel 30 microg, or norethisterone 350 microg, was effective in preventing sperm migration in the cervical mucus about 12 hours later. This suggests that the progestogen-only pill may be effective as a 'morning befor...
