RNA molecules and proteins are accumulated in the oocyte cytoplasm during its growth
phase and are used to sustain the early phases of embryonic development before embryo …

Among the components of the female reproductive tract, the ovarian pool of follicles and
their enclosed oocytes are highly sensitive to hyperthermia. Heat-induced alterations in …

Mitochondria play a key role in a number of physiological events during all stages of life,
including the very first stages following fertilization. It is, therefore, important to understand …

The objectives were 1) to investigate the effects of oocyte maturation in serum-free and
amino acid-supplemented defined media on oocyte transcript levels, blastocyst cell number …

Research on spermatozoal RNA has made considerable progress since the original reports
on its presence appeared in the late 1950s and early 1960s. Through the use of stringent …
