Effects of Nitric Oxide Synthase Inhibitors on Equine and Bovine Follicular Dynamics and Steroidogenesis.
TL;DR: Administration of NOS inhibitors delayed ovulation in mares and cows, and intrafollicular production of NO was up-regulated following hCG administration, demonstrated that L-NAME has a short half life in horses and L-NNA is a major metabolite with a relatively long half life.

The Effects of Equine Somatotropin on Pituitary and Testicular Function in the Stallion During the Nonbreeding Season
TL;DR: Somatotropin treatment for 21 days may alter the long-term accessory gland contribution to seminal volume but does not appear to alter pituitary gonadotrope function or testicular testosterone secretion.

Effects of frequency of treatment with recombinant equine somatotropin on selected biological responses in geldings
C.E. Thatcher,D.L. Thompson +1 more
TL;DR: The optimum injection regimen for any new application for eST cannot simply be inferred from other biological responses, and will need to be determined empirically, as the efficacy of daily versus every-other-day injections of eST depends upon the response to be measured.

Control of follicular development and ovulation rate in pigs
TL;DR: In a series of studies involving insulin administration between weaning and oestrus, successive experiments produced different results, but several measures of reproductive performance were enhanced as mentioned in this paper, including the quality of ova and whether the increase in ovulation rate exceeds the uterine capacity to maintain pregnancy.
Body Condition, Leptin, and Reproductive Characteristics in Horses.
TL;DR: Responses to hormonal challenges indicated cyclicity in HBCS mares and reproductive quiescence in LBCs mares, and leptin may be produced in part by the placenta.

An improved culture medium supports development of random-bred 1-cell mouse embryos in vitro
TL;DR: The in-vitro development of 1-cell embryos beyond the 2-cell stage in response to the removal of glucose and the addition of glutamine to the culture medium suggests that glucose may block some essential metabolic process, and that glutamine may be a preferred energy substrate during early development for these mouse embryos.

Insulin-like growth factors as intraovarian regulators of granulosa cell growth and function.
TL;DR: The findings indicate that Sm-C/IGF-I synergizes with FSH in the induction of rat granulosa cell aromatase activity at nanomolar concentrations compatible with its granULosa cell receptor binding affinity, and can be added to a growing list of growth factors known to modulate granul Rosa cell growth and function.

Association between surges of follicle-stimulating hormone and the emergence of follicular waves in heifers.
TL;DR: It was concluded that the dominant follicle on Day 3 and Day 5 was associated with the suppression of circulating FSH concentrations and the effects of exogenous follicular fluid on follicular development were mediated, in whole or in part, by altering plasma F SH concentrations.

Pregnancy after in vitro fertilization of human follicular oocytes collected from nonstimulated cycles, their culture in vitro and their transfer in a donor oocyte program *
TL;DR: In this paper, the results with immature human follicular oocytes harvested from unstimulated ovaries, matured in vitro, fertilized, and transferred to an agonadal recipient were described.
