Prostaglandin E1 Inhibits Abnormal Follicle Rupture and Restores Ovulation in Indomethacin-Treated Rats
TL;DR: Prostaglandins of the E series, and especially PGE1, inhibited abnormal follicle rupture and restored ovulation, although the number of oocytes in the oviducts were significantly decreased and PGF2α was only partially effective in inhibiting abnormal follicles rupture and restoring ovulation.
Journal ArticleDOI
Estrogen causes ultrastructural changes of fibrin networks during the menstrual cycle: A qualitative investigation
TL;DR: Hormonal fluctuations may influence fibrin structure, mainly due to the variations of estrogen, in women during the menstrual cycle.
Journal ArticleDOI
Characterization of Temporal and Cell-Specific Changes in Transcripts for Prostaglandin E2 Receptors in Pseudopregnant Rat Endometrium
Karen D. Papay,Thomas G. Kennedy +1 more
TL;DR: Results support a role for PGE2 in the onset of receptivity and initiation of decidualization in the rat.
Journal ArticleDOI
Sexual differences in weight loss upon eclosion are related to life history strategy in Lepidoptera
TL;DR: Weight loss in eclosing insects is generally facilitated by a high water content, while adults excrete water upon eclosion to benefit flight unless water has been allocated to eggs, or is treated as a capital resource for adult survival or future allocation to eggs.
Journal ArticleDOI
Reverse stridulatory wing motion produces highly resonant calls in a neotropical katydid (Orthoptera: Tettigoniidae: Pseudophyllinae)
TL;DR: The mechanics of stridulation used by males of the neotropical katydid Ischnomela gracilis (Pseudophyllinae) are described, and the song of this species is produced by resonance.

Seasonal breeding:nature's contraceptive.
G A Lincoln,Roger V. Short +1 more
TL;DR: The seasonal cycle highlights the seasonal changes in daylight length, rutting behavior, testicular diameter, sexual skin flush, and concentrations of plasma follicle-stimulating hormone, prolactin, and testosterone in a group of rams throughout the year.
Journal ArticleDOI
The physiological responses of anovulatory ewes to the introduction of rams: a review.
TL;DR: Ewes of many breeds can be stimulated to ovulate by the reintroduction of rams and appear to be effected both through a delay in the onset of the LH surge and through a direct action of progesterone on the ovary.
Journal ArticleDOI
Factors affecting the secretion of luteinizing hormone in the ewe.
TL;DR: LH is secreted as discrete pulses throughout all stages of the reproductive cycle of the ewe, including pre‐pubertal, seasonal and lactational anoestrus, and the luteal and follicular phases of the oestrous cycle.
Nutritional influences on reproduction in mature male sheep and goats
TL;DR: In this article, it was shown that nutritional signals exert powerful effects on the reproductive system of mature male ruminants, and the responses are partly independent of changes in gonadotrophin secretion.
