[Comparative light- and electron microscopy findings in oocytes obtained by laparoscopy during the cycle period close...

Oocytes recovered by diagnostic laparoscopy can be divided in three categories--atretic, non-ovulatory and pre-ovulatory oocytes. Examples for those three categories are demonstrated. The findings from survey sections and from transmission electron microscopy were used for the retrospective characterization of the light micrographs and the description of the surroundings. Methodic experiences allow further research on oocytes and embryos with developmental defects. Two examples were shown. Our experiments yielded, that the examination with light and electron microscopy is suitable for statement in diagnostic laparoscopies and that these examinations were advantageous for the preparation of an in vitro fertilization program.
