[True hermaphroditism and double fertilization].

Journal de genetique humaine, 1987
Two cases of true hermaphroditism are presented. Sex differentiation mechanism, X functions in skin development and pigmentation are studied. Lateral gender assignment in hermaphroditism and mythologic concept right side = maleness and left side = femininity are compared.

Double fertilization in flowering plants: 1898–2008

Cytology and Genetics, 2008
The present article gives a brief survey of results of studies in the area of plant embryology directly associated with the discovery made by S.G. Navashin in 1898 of double fertilization in vivo and in vitro. These studies utilized methods of electronic and fluorescence microscopy, cytophotometry, and cultures of isolated ovules, sperm, and the embryo

Deep learning versus manual morphology-based embryo selection in IVF: a randomized, double-blind noninferiority trial

Nature Medicine
To assess the value of deep learning in selecting the optimal embryo for in vitro fertilization, a multicenter, randomized, double-blind, noninferiority parallel-group trial was conducted across 14 in vitro fertilization clinics in Australia and Europe ...
