Physiology and modulation factors of ovulation in rabbit reproduction management
World Rabbit Science, 2021 Rabbit is an induced ovulatory species, so ovulation takes place after mating. Traditionally, exogenous and synthetic hormonal factors (administered by intramuscular and intravaginal route) such as GnRH and analogues, or different physical procedures (i ...

Frustration-induced inherent instability and growth oscillations in pollen tubes [PDF]
, 2012 In a seed plant a pollen tube is a vessel that transports male gamete cells to an ovule to achieve fertilization. It consists of one elongated cell, which exhibits growth oscillations, until it bursts completing its function. Up till now, the mechanism behind the periodic character of the growth has not been fully understood.

The Anatomical Record, EarlyView.Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

A high-throughput analysis of ovarian cycle disruption by mixtures of aromatase inhibitors [PDF]
arXiv, 2016 Background: Combining computational toxicology with ExpoCast exposure estimates and ToxCast assay data gives us access to predictions of human health risks stemming from exposures to chemical mixtures. Objectives: To explore, through mathematical modeling and simulations, the size of potential effects of random mixtures of aromatase inhibitors on ...

Ovulation induction in perspective [PDF]
Human Reproduction Update, 2002 It has been suggested recently that, in some quarters, IVF be offered as first-line therapy to all infertile couples, regardless of the type of infertility. Hence, the time was thought right to scrutinise the results and complications of ovulation induction for anovulatory infertile couples.

Clomiphene and other antioestrogens for ovulation induction in polycystic ovarian syndrome.
Cochrane Database of Systematic Reviews, 2016 BACKGROUND Subfertility due to anovulation is a common problem in women. First-line oral treatment is with antioestrogens such as clomiphene citrate, but resistance may be apparent with clomiphene.
