Panguva yekutanga kwekuyaruka, chiyero cheestrogen chinobudiswa chinowedzera kuwedzera. Iyo hypothalamus, sezvazvakaita, inoshandura "zvirongwa" uye "inobvumira" kukwirira kwakanyanya kweesrogen muropa. Izvi zvinowanzobatanidzwa nekuwedzera kweuviri hwemuviri.
Nemhaka yepamusoro yeestrogen uye progesterone (iyo inogadziriswa nemaovhesi mushure mekuvhara ropa) muropa, zvakasiyana-siyana zvehupenyu zvinoitika mumuviri.
Iyo yakakura yehomoni inobatana zvikuru nehuwandu hwemafuta emuviri. Saka, kazhinji mumusikana, mafuta anowanikwa mumuviri mauri pasi, zvinokonzerwa kucheka kutaridzika kwenguva yekupera.
Vasikana vanobudisawo mahomoni akaita se testosterone uye androgens, asi maitiro avo akaderera. Zvinokanganisa kuchinja kwemuviri mumuviri, somuenzaniso, nekusimudzira kukura kwemvere dzomuviri.
Nemhaka yehupamhi hwemahomoni mumuviri munguva yekuyaruka, vasikana vanogona kunzwa kusagadzikana mupfungwa, kazhinji kacho mafungiro akaoma anochinja, manzwiro ekuzvidya mwoyo.
Hormonal inoshandiswa muvakadzi
Sezvambotaurwa pamusoro, nguva yechipiri yekuchinja kwehomoni inotangira makore makumi mashanu, zvichikonzera zvakanyanya nharaunda yemanzwiro, ayo asingagoni asi kukanganisa ukama hwemhuri. Kazhinji munguva ino yehukama hunoedzwa simba.
Makore mashomanana kusati kwatanga kumisa, iwe unogona kuona kuderera kwemazinga emahomoni anobudiswa nemavhizha. Kune zvishoma uye zvishomanana follicles zvine dhi, uye nekuuya kwekuguma kwemwedzi vanonyangarika zvachose. Izvi zvinotungamirira kuchokwadi chokuti progesterone uye estrogen inopedza kubudiswa, hapana hutano huripo uye kuenda kumwedzi kunonyangarika.

Zviratidzo zvinonyanya kuonekwa zvekushandura mu-hormonal balance panguva ino ndeizvi:
- Hazvibviri kutora pamuviri, se, sezvakataurwa pamusoro apa, follicles ine egg inopera.
- Kuderedza chido chepabonde. Sezvo mutemo, izvi zvinokonzerwa nekuti kusaenzana kwemashure kunokonzera kuoma mukati mechikadzi uye kusagadzikana munguva yepabonde. Uyewo, kukwezva kunogona kuderera nekuda kwekusava nechokwadi, nokuti shamwari yehutoni inoshandura inowanzosagadzikana mupfungwa, iyo inotungamirira ku kuora kwehukama naye. Kuchema kunogona kukonzerwa nekuderera kwehuwandu hweesrogen yakagadzirwa, iyo inoitawo kuti mazamu masvingo asaputike. Mazana makuru maitiro anoshanduka maitiro, kuonda. Zvose izvi zvinowedzerawo kuderera mune zvepabonde
- Nezvekuderera kwemazinga emahomoni, hutano hwechido chepabonde hunoderera, kunyange zvazvo testosterone, iyo inonyanya kukonzera chido chepabonde, inoenderera mberi kubudiswa mumayamu. Zvisinei, pasinei neizvi, zvidzidzo zvenguva pfupi zvakaratidza kuti vakadzi vane unogara nekugadzirisa vanogona kuchengetedza zvekuita zvepabonde imwechete uye basa sekutanga. Uyezve, inenge makumi mana kubva muzana yevakadzi vanoongorora vanocherechedza kuti nekudzivirira kwakakodzera uye kurapwa, zvepabonde ravo rinoshanda panguva iyi zvakanyatsovandudzika uye zvinokubvumira kuwana mufaro mukuru kubva kune zvepabonde.
