prolonged period firstly during oocyte growth, and then when awaiting the appropriate …

A primary reason behind the high level of complexity we embody as multicellular organisms
is a highly complex intracellular and intercellular communication system. As a result, the …

Across the animal kingdom, environmental light cues are widely involved in regulating
gamete release, but the molecular and cellular bases of the photoresponsive mechanisms …

The reproductive hormones that trigger oocyte meiotic maturation and release from the
ovary vary greatly between animal species. Identification of receptors for these maturation …

Obesity negatively affects many aspects of the human body, including reproductive function.
In females, the root of the decline in fertility is linked to problems in the oocyte. Problems …

In some insect species, two sites of juvenile hormone (JH) synthesis have been reported: the

Cnidarians are widely distributed basal metazoans that play an important role in the marine
ecosystem. Their genetic diversity and dispersal depends on successful oogenesis …

In various oocytes and eggs of animals, transient elevations in cytoplasmic calcium ion
concentrations are known to regulate key processes during fertilization and the completion …

Oocyte maturation and subsequent spawning in hydrozoan jellyfish are generally triggered
by light‐dark cycles. To examine if the initiation of the maturation process after light stimulus …
