Oocyte selection

Suɓagol ƴiiƴam ko feere waɗeteende ko adii jibinannde e nder geese, ngam huutoraade ƴiiƴam ɓurɗam waawde jibinde reedu. Ko feewti heen, suɓagol ɓiɗɗo ina waɗa caggal jibinannde.

Wonaa rewɓe fof mbaawi jibinde e nder nguurndam mum en, ɗum noon ina addana ɗum en soklaade karallaagal e wiɗtooji baawɗi wallude ɗum en jibinde.

In vitro fertilisation ina waawi wonde safaaraaji keewɗi, tawa ina waɗi jibinannde eggudu mawndu e ƴiiƴam e nder laboratuwaar. Suɓagol oosit ko huunde e golle ngam jibinde e nder geese. Oocyte ko eggudu/ovum mo timmaani walla ƴellitaaki, mo njibinaaka ; Ko ɗum waɗi oosit ko ovum mo ƴellitaaki.

Suɓaade oosit ngam jibinde e nder geese ina ɗaɓɓi ƴeewtaade sifaa oosit oo ko heewi waɗeede ko e heɓde sifaaji morfolooji oosit oo. Feccere mawnde e oosit keɓtinaande ngam kalite to bannge sifaaji morfolooji ko ƴiye kuuɓtodinɗe, zona pellucida, ɓanndu polaar, nokku perivitellin, e sitoplasma ; Ko ɗeen ngoni geɗe teeŋtuɗe e nder ƴiiƴam, ɗe keewi ƴeewteede ko e mikroskoop kuutorteeɗo.

Kadi, sifaaji morfolooji oosit baawɗi heɓde e mikroskoop annoore gonnde e mbaydi walla annoore polarize. Kono tan, alaa ko laaɓti e binndanɗe cakkitiiɗe ɗee ko fayti e ɓeydagol kuuɓtodinngol nafoore teskaande sifaaji morfolooji.Teknikaaji teskinɗi ina mbaɗi ƴeewndo zona pellucida, baawɗo yiytude ceertugol birefringence hakkunde egguuji, ko ɗum teskaade compaction, blastulation e reedu.

E ko waawi wonde fof, biopsie ɓanndu polar ina waawi huutoreede ngam yuurnitaade molekulaaji, kadi ina waawi huutoreede ngam yuurnitaade taariindi ko adii jibineede.
