dc.description.abstractOocyte’s maturation is a very important process in fertility because it is necessary for subsequent fertilization. In addition, maturation process influences the embryo, since the quality of the developing embryo is directly related to the maturity and the quality of the oocyte. This growth culminates just prior to ovulation during oocyte maturation. Adequate nuclear and cytoplasmic changes associated with maturation process of oocytes are fundamental for correct ovulation and subsequent fertilization. One of the main challenges is to determine the molecular pathways that regulate that maturation process. In addition, to better understanding female reproductive physiology, we could help to optimize the reproductive techniques by modulating the process of oocyte in vitro maturation, through the IVM technique. This technique consists in turning immature oocytes to mature exogenously in a culture media supplemented with different molecules to promote maturation. The most important advantage of IVM method is that could be the only hope or, at least, an alternative for a high number of patients unable to tolerate high doses of gonadotropins. Among the ARTs, the in vitro maturation oocytes (IVM) is less developed than other techniques, but its implementation would entail a qualitative advance.; Ugaztun emeen obozitoen heltze-prozesua ugalkortasunean garrantzi handia duen prozesua da, obulua ernaldua izateko ezinbestekoa delako. Gainera, heltze-prozesuak baldintzatzen du sortu behar den izaki berria, garapen-bidean dagoen enbrioiaren kalitatea zuzenean lotuta baitago obozitoaren heldutasunarekin eta kalitatearekin. Izan ere, obozitoen heltze-prozesuarekin erlazionatutako aldaketa nuklear eta zitoplasmatiko egokiak funtsezkoak dira obulazio eta haren ondorengo ernalketa zuzen baterako. Erronka nagusietariko bat da, beraz, heltze-prozesuan garrantzitsuak diren seinaleztapen-bidezidorrak eta elkarrekintza konplexuak zehaztea. Horrela, emakumezkoen ugal-fisiologia hobeto ulertzeaz gain, obozitoen in vitro heltze-prozesua modulatuz, lagunduriko ugalketa-teknikak optimizatzen lagundu genezakeelako: besteak beste, obozitoak in vitro heltzeko (IVM) teknika. Teknika horren bidez, pazienteari oraindik helduta ez dauden obozitoak erauzten zaizkio eta exogenoki heltzen dira hazkuntza-inguruneetan. Modu horretan, albo-kalte ugari eragiten dituen gonadotropinak hartzea saihesten da, eta hormonazioa kontraindikaturik daukaten emakumeentzat haurdun geratzeko aukera bakarrenetarikoa da. Teknika horren ezarpenak aurrerapen ugari dakartzan arren (esaterako, albo-kalte eta kostu ekonomiko gutxiago), oraindik gutxi erabiltzen da, beste ugal-tekniken arrakasta-mailara heldu ez delako.
