Currently, a large number of predatory journals have proliferated. Their purpose is to obtain fraudulent profits by promising the rapid publication of scientific works, without fulfilling the services of quality review. These publishers have managed to copy the models of open access journals, which is why they are increasingly difficult to identify, coupled with the fact that many of them have opened spaces in the most important indexes of scientific journals, such as Medline, Web of Science (WoS), Scopus, Embase, among others.

Oxytocin and vasopressin share a similar chemical structure but have different functions. Both hormones are produced in different brain areas, are transported through the hypophyseal portal system, pass to the anterior hypophysis, and released to reach their target organs. These hormones also act as neuromodulators, where its receptors are found in the lateral septum, the middle amygdala, the hippocampus, the hypothalamus, and the brain stem.

The two cervical regions are bordered by the cervical transformation zone (CTZ), an area of changing cells, and are predominantly composed of cervical epithelial cells. Epithelial cells are known to play a crucial role in the initiation, maintenance, and regulation of innate and adaptive response in collaboration with immune cells in several tissue types, including the cervix, and their dysfunction can lead to a spectrum of clinical syndromes.

As with other members of the glycoprotein hormone family, FSH is produced and released as an array of isoforms that differ from each other in the structure of their oligosaccharide attachments. In this review, we discuss how carbohydrate heterogeneity can impact on FSH action in different in vitro and in vivo systems.

In spite of improved results through several important innovations, the pregnancy rate per collected oocyte remains far too low. In order to improve this situation, it is necessary to learn more about fundamental factors modulating follicular development patterns.
