Kureba kweiyo ovarian kutenderera kunosiyana zvakanyanya kubva kune mumwe mukadzi kuenda kune mumwe, uye kunyange kubva kune imwe kutenderera kuenda kune imwe. Muchiitiko chekufamba kwenguva refu kumwedzi, ovulation inonzwisisika inoitika gare gare, pasina kukanganisa kubereka.

Sechiyeuchidzo, iyo ovulatory cycle inoumbwa nezvikamu zvitatu zvakasiyana:

• chikamu che follicular inotanga pazuva rokutanga rokuenda kumwedzi. Inoratidzwa nekukura kwemaovarian akawanda follicles pasi pekuita kwe follicle-stimulating hormone (FSH);
• ovulation inofananidzwa nekudzingwa kweoocyte neiyo huru ovarian follicle iyo yasvika pakukura, pasi pekuita kwe luteinizing hormone (LH) kuwedzera;
• panguva ye luteal kana post-ovulatory phase, "chigamba chisina chinhu" chefollicle chinoshanduka kuva corpus luteum, iyo inotanga kubudisa progesterone, iyo basa iri kugadzirira chibereko chekugonesa kuiswa kwezai rakagadzirwa. Kana pasina kumbove nekugadzirwa, kugadzirwa uku kunomira uye endometrium yakavharwa kubva pamadziro echibereko: iyi ndiyo mitemo.

Ovarian cycle inotora avhareji yemazuva makumi maviri nemasere, uye ovulation pazuva rechigumi nemana. Zvisinei, kureba kwekutenderera kunosiyana pakati pevakadzi, uye kunyange pakati pemazamu mune vamwe vakadzi. Luteal phase ine nguva yakarebesa yemazuva gumi nemana, muchiitiko chenguva refu (kupfuura mazuva makumi matatu), follicular phase inorebesa. Ovulation saka inoitika gare gare mukutenderera. Semuenzaniso, kutenderera kwemazuva makumi matatu nemaviri, ovulation ichaitika pazuva regumi nemasere rekutenderera (28-14 = 14).

Nekudaro, iyi ingori yekuverenga kuverenga. Muchiitiko chekutenderera kwakareba uye / kana kutenderera kusingaenzaniswi, kuwedzera mikana yekuzvitakura, zvinokurudzirwa kune rumwe rutivi kusimbisa kuti kune ovulation, kune rumwe rutivi kuti uone zuva rayo zvakavimbika. Kune nzira dzakasiyana dzeizvi idzo mukadzi anogona kuita ari oga, kumba: tembiricha curve, kucherechedzwa kwecervical mucus, iyo yakasanganiswa nzira (tembiricha curve uye kucherechedza cervical mucus kana zvakare kuvhurwa kwecervix) kana ovulation bvunzo. Iyo yekupedzisira, zvichibva pakuonekwa muweti yekuvhiya kweLH, kuve yakanyanya kuvimbika yekufambidzana ovulation.

Hatizivi zvikonzero zvekunonoka ovulation. Isu dzimwe nguva tinotaura nezve "usimbe" mazai pasina izvi kuve pathological. Isu tinoziva zvakare kuti zvinhu zvakasiyana-siyana zvinogona kukanganisa nguva yekutenderera nekupesvedzera iyo hypothalamic-pituitary axis pamavambo ehomoni secretions yeFS neLH: kushomeka kwechikafu, kuvhunduka kwemanzwiro, kushushikana kwakanyanya, kuderera kwehuremu kamwe kamwe, anorexia, zvakanyanya. kurovedza muviri.

Mushure mekumisa piritsi rekudzivirira, zvinowanzoitika kuti matenderedzwa ave akareba uye / kana kusarongeka. Imbozorora kwenguva yekudzivirira kubata pamuviri, mazai anogona kutora nguva shoma kuti atangezve kuita zvakajairika.

Kunonoka ovulation hakufanirwe kuve kwakashata ovulation. Chidzidzo cheSpanish chakaburitswa muna 2014 mukati European Journal yeObstetrics & Gynecology, inotoratidza zvinopesana (1). Vatsvakurudzi vakaongororawo maovarian cycles evakadzi vangangosvika 2000 vakapa oocytes, uye chiyero chepamuviri mune vanogamuchira. Mhedzisiro: mupiro wezai kubva kuvakadzi vane majekiseni marefu wakabatanidzwa nechikamu chepamusoro chekuzvitakura kune vanogamuchira, zvichiratidza zvirinani maoocyte.

Kune rumwe rutivi, kureba kwacho kutenderera, kunenge kuri kushoma mukati megore. Kuziva kuti hwindo rekubereka rinongotora mazuva mana kusvika mashanu chete pachiyero uye kuti mikana yekubata pamuviri iri paavhareji 4 kusvika 5% pachikamu chega chega kune vakaorera vanoita bonde panguva yakanakisa yekutenderera (15), mukati chiitiko chenguva refu, mikana yekuzvitakura ichave yakanyanya kuderedzwa.

Kana matenderedzwa akapatsanurwa kunze nepo aimbove aavhareji yenguva (mazuva makumi maviri nemasere), zvinokurudzirwa kubvunza kuti uone dambudziko rinogona kuitika rehomoni.

Dzimwe nguva kutenderera kwenguva refu uye / kana kusakwana kunogona kuva chimwe chezviratidzo, mumufananidzo wakazara, we polycystic ovary syndrome (PCOS) kana ovarian dystrophy, endocrine pathology inobata 5 kusvika 10% yevakadzi vezera rekubereka. kubereka. PCOS haisi nguva dzose inokonzera kushaya mbereko, asi ndicho chikonzero chinowanzokonzera kusabereka kwevakadzi.

Muzviitiko zvose, pasinei nekureba kwekutenderera, zvinokurudzirwa kubvunzurudza mushure memwedzi gumi nemaviri kusvika ku12 yekusabudirira kwevana miedzo. Mushure memakore makumi matatu nemasere, nguva iyi inodzikiswa kusvika pamwedzi mitanhatu nekuti mbereko inodzikira zvakanyanya mushure mezera iri.
