The discovery of progesterone (P4) and elucidation of the mechanisms of P4 action have an
important place in the history of endocrinology and reproduction. Circulating P4 …

Within the sperm nucleus the paternal genome remains functionally inert and protected
following protamination. This is marked by a structural morphogenesis that is heralded by a …

The gamete recognition and initial binding processes that are crucial for the success of
mammalian fertilization are mediated by moieties associated with the extracellular matrix of …

There is a dialogue between the developing conceptus (embryo-fetus and associated
placental membranes) and maternal uterus which must be established during the peri …

Anovulation is a major cause of infertility, and it is the major leading reproductive disorder in
mammalian females. Without ovulation, an oocyte is not released from the ovarian follicle to …

The mammalian ovary is a dynamic organ. The coordination of follicle recruitment, selection,
and ovulation and the timely development and regression of the corpus luteum are essential …

The spectrum of vitamin D (VD)-mediated effects has expanded in recent years, and VD is
now recognized as a versatile signaling molecule rather than being solely a regulator of …

Objectives were to determine the effects of GnRH at the initiation of the 5-d timed artificial
insemination (AI) program combined with 2 injections of PGF 2α on ovarian responses and …

MicroRNAs (miRNAs) constitute a large family of noncoding RNAs, approximately 22
nucleotides long, which function as guide molecules in RNA silencing. Targeting most …

The primate corpus luteum is a transient endocrine gland that differentiates from the
ovulatory follicle midway through the ovarian (menstrual) cycle. Its formation and limited …
