Abstract
The biophysical changes in the cervical secretion determine, and can influence the viscosity, which is directly proportional to the estrogenic impregnation, which varies from the initial follicular phase to the luteal phase, and is maximum in the periovulatory phase. Currently most studies define the period of greatest fertility from day -6, prior to ovulation, until the first day after ovulation, and it is in this time interval when the change of days usually happens. Infertile, to the days of greatest fertility in the follicular phase of the menstrual cycle [1]. Currently it is known that the variability in the composition and production of cervical mucus is clearly regulated by the production of estradiol. Which during the preovulatory period, it becomes of the order of 600 to 700 mg/day, and outside the fertile window about 40 or 60mg. This quantifiable difference in the amount of estrogen clearly determines type E (estrogenic) secretion, which is abundant, and can be quantified in quantity, appearance; transparency, consistency and stretching. These physiological findings are widely documented in the literature in several studies that confirm the trophic effects mentioned both at the serum and local levels [2-8]. The changes that occur from the follicular phase to the end of the luteal phase will determine the variability of changes in the biophysical properties of cervical secretion. There are currently several entities that have devoted great efforts to improve the recognition of fertility within the fertile window. Among them are, for example, ovulation issues, cervical secretion or fertile window: International Federation for Family Life Promotion (IFFLP) (now Link Committee of Family Life Organizations), World Organization Ovulation Method of Billings, European Institute for Family Life Education (EIFLE), Africa Family Life Federation (AFLF) or with universities (Institute for International Studies in NFP Georgetown University IISNFP, NFP ForschungsprojektNatürlicheFamilienplanung an der Universität Düsseldorf, Rome Center for Study and Research on Natural Fertility ISI Regulatory, and Omaha Pope Paul VI Institute for the Study of Human Reproduction, among others. These schools describe the fundamental changes, which obey the physiological effect produced by the trigger effect produced on estrogen at the threshold of FSH. From the physiological premise of Brown[9], who comes to say that at FSH levels between 15 to 20 milli units/mL, there is an elevation of estradiol above baseline values, which in turn determines that the Follicular development responds to a certain threshold of FSH. This physiological effect determines that the recruited follicle progresses evolutionarily to a dominant follicle in physiological situations of normality. Through a citation of novel studies in this regard based on the application of the classic studies of the Billings evolutionary recognition pattern, up to the present date the following analysis can be reached as seen in Figure 1. Taking into account an algorithm developed to relate citation technology [10], network models [11] and the innovation approach of Burt [12], a network analysis was performed following indegree centrality according to Wasserman [13]. For the elaboration of this analysis, some of the citations related to the recognition of fertility have been taken, which are summarized in Table 1, Figure 1 and Figure 2 shows how the most cited patent is US 4151831 and around there are 3 other patents with a smaller number of citations. Likewise, another 5 subgroups of patents can be seen as shown in Figure 1. This set of patents is fragmented and are not related to each other, which are treated in different subgroups of topics related to the recognition of fertility.By including in the analysis, two more patents related to the biophysical characteristics of the cervical secretion (patents in red in Figure 2), contributed by the search of the World Intellectual Patent Office (WIPO); Three different effects can be seen as seen in Figure 2. The first effect in terms of the patent US2011106465 provided as a novelty in the search, which links to the set of most cited patents. This effect occurs through one of the two routes originated in the patent US899882282. A route is from US20130054150A1, cited by US201100331720A1. And the other originated route is from US899882282 and links the patent US2011106465 provided by WIPO with the most cited patent US4151831A. The other effect is observed is the patent US2014313322, which is not articulated with the rest of the patents. And the third effect is highlighted by the patents enclosed in green Circles. These patents become intermediaries (bridges) between important groups of patents. The most obvious case is presented in the bridge established between patents US4151831A and US3434810A. And for our analysis it is of particular interest because the patent US4151831A is an intermediary between the patent found by WIPO; US2011106465 and the most cited patent of all US4151831A.
