Influence of copper intrauterine contraceptive devices (Cu-7-IUD) on the menstrual blood-loss.

In a series of 43 healthy women menstrual blood loss was determined before and after insertion of copper IUD (Gravigard). The menstrual blood loss before insertion was compared with the blood loss 1, 2, 3, 4, 5, 6, 7 and 12 months after insertion. An increase amounting to approximately 20 ml per period without significant variations during the study was recorded. No significant influence upon serum iron and TIBC was found in 15 of the subjects selected by random. Compared with plastic IUD's the tested copper IUD causes a less pronounced increase of the menstrual blood loss. The menstrual blood loss in a small group of women with menorrhagia was determined before and up to 5 months after insertion of copper IUD. No aggravation of the menorrhagia was however recorded in this group.

Internalization of cellular fragments in a human embryo: time-lapse recordings.

An observation is reported of internalization of a cellular fragment into a blastomere from a human embryo, as documented by time-lapse photography. The fragment, created during the first mitotic cleavage was reabsorbed into one of the mother blastomeres in less than 5 min. The time-lapse sequence, shown here as a series of still photographs, provides the first direct evidence that cellular fragments in human embryos can 'disappear' during the culture period, a phenomenon that is common in human IVF. The time-lapse sequence itself may be viewed on the internet at www.rbmonline.com/Article/633.
