[Occurrence of recombination nodules in the synaptonemal complex of the human oocyte at the pachytene stage].

In the human oocyte at pachytene the synaptonemal complex displayed electron-dense bodies mostly oval shaped and associated with the central element. Their dimensions were about 50 x 100 nm. The morphological features of these bodies were similar to those of recombination nodules observed in germinal cells of a number of animal and plant species.
