Piritsi rekudzivirira kubata pamuviri rinosanganisira kuvharira ovulation nekuda kwemahomoni akasiyana ayo achaita pane hypotalamic-pituitary axis, cerebral axis yekudzora maovari, ivo pachavo pamavambo eakasiyana mahomoni ekubuda kweiyo ovulatory cycle. Chiito ichi chinodzokororwa kana piritsi rangomiswa, zvisinei nekuti rinotora nguva yakareba sei. Zvisinei, dzimwe nguva tinocherechedza "usimbe" apo basa re hypotalamo-pituitary axis uye maovari inotangazve (1). Chiitiko ichi chinosiyana zvakanyanya pakati pevakadzi, zvisinei nekuti piritsi rinotora nguva yakareba sei. Vamwe vanozowanazve ovulation nekukurumidza kana kutenderera mushure mekumisa piritsi, nepo mune vamwe, zvinotora mwedzi mishoma kuti itangezve kutenderera kwakajairika neovulation.

Kare, mamwe magynecologists aikurudzira kumirira mwedzi miviri kana mitatu mushure mekumisa piritsi kuitira kuti awane ovulation iri nani uye uterine lining. Nekudaro, mazuva ekupedzisira aya haana kuvakwa mune zvekurapa. Hapana chidzidzo chakakwanisa kuratidza kuwedzera kwehuwandu hwekusagadzikana kana kukanganisa, kana kutora mimba yakawanda muvakadzi vakave nepamuviri apo piritsi rakamiswa (2). Saka zvinokurudzirwa kumisa piritsi kubva panguva yaunoda kubata pamuviri. Saizvozvo, hazvina kurongeka mune zvekurapa kutora "mazororo" uchitora piritsi kuti uchengetedze kubereka.

Zvinoitika kuti piritsi, iro rinokonzera mitemo yekugadzira nekuregera kubuda ropa (kuburikidza nekudonha kwemahomoni pakupera kwepakiti), ine masked ovulation kusagadzikana, iyo. inozoonekwazve paunomira kunwa piritsi. Zvikonzero zvinowanzoitika ndezvekuti hyperprolactinemia, polycystic ovary syndrome (PCOS), anorexia nervosa kana kukundikana kweovarian nguva isati yakwana (3).

Imwe yematambudziko makuru evakadzi pamusoro pepiritsi ndeye mhedzisiro yaro pakubereka, kunyanya kana rikanwiwa nguva dzose kwemakore mazhinji. Basa resainzi rinosimbisa pachinhu ichi.

Chidzidzo (4) chakaitwa mukati mehurongwa hweEuras-OC (chirongwa cheEuropean chekuongorora zvakasimba pazvirongwa zvekudzivirira pamuviri) uye chaisanganisira vakadzi makumi matanhatu vanonwa kudzivirira kubata pamuviri kwakaratidza kuti mwedzi wakatevera kumisa mapiritsi, 60% yavo vaive nepamuviri. Iyi nhamba inoenderana neiyo yekubereka kwepanyama, inowanzoratidza kuti piritsi harina kukanganisa kubereka uye mikana yekuzvitakura. Ongororo iyi yakaratidza zvakare kuti nguva yekutora mapiritsi hainawo kukanganisa pamikana yekuve nepamuviri: 000% yevakadzi vakatora piritsi iri pasi pemakore maviri vakava nepamuviri mukati megore, zvichienzaniswa ne21% pakati pevakadzi vakashandisa. kweanopfuura makore maviri.

Kana pasina kunonoka pakati pekumisa piritsi uye kutanga kuyedza kubata pamuviri, zvinokurudzirwa zvakanyanya kubvunza chiremba wako wevakadzi, chiremba mukuru kana nyamukuta usati wamisa piritsi. yekubvunzana. Kubvunzana uku, kwakakurudzirwa neHaute Autorité de Santé (5), kunosanganisira:

• kubvunzurudzwa nezvekurapa, kuvhiya, nhoroondo yekuzvara
• kuongororwa kwekiriniki
• cervical dysplasia screening smear kana inopfuura makore maviri kusvika matatu
• bvunzo dzemurabhoritari: mapoka eropa, tsvaga irregular agglutinins, serology ye toxoplasmosis uye rubella, uye pamwe kuongorora HIV, hepatitis C, B, syphilis.
• folic acid kuwedzera (vitamin B9)
• kubata-up vaccination ye rubella, pertussis, kana isiri kusvika parizvino
• kudzivirira mararamiro engozi: kusvuta, doro uye kushandisa zvinodhaka
