Iphilisi lokuvimbela inzalo liqukethe ukuvimbela i-ovulation ngenxa yamahomoni ahlukene azosebenza ku-hypotalamic-pituitary axis, i-cerebral axis yokulawula ama-ovari, ngokwawo emsuka wokuphuma kwamahomoni ahlukahlukene omjikelezo we-ovulatory. Lesi senzo siyabuyiselwa emuva ngokushesha nje lapho iphilisi limiswa, kungakhathaliseki ubude balo bokusetshenziswa. Nokho, ngezinye izikhathi sibona “ubuvila” lapho umsebenzi we-hypotalamo-pituitary axis kanye namaqanda eqala kabusha (1). Lesi simo siyehluka kakhulu kwabesifazane, kungakhathaliseki ukuthi iphilisi lithatha isikhathi esingakanani. Abanye bazophinde bathole i-ovulation ngokushesha ngemva komjikelezo ngemva kokumisa iphilisi, kanti kwabanye, kuzothatha izinyanga ezimbalwa ukuze kuqalwe kabusha umjikelezo ovamile nge-ovulation.

Ngaphambilini, abanye odokotela bezifo zabesifazane batusa ukulinda izinyanga ezi-2 noma ezi-3 ngemuva kokumisa iphilisi ukuze bathole i-ovulation engcono nolwelwesi lwesibeletho. Kodwa-ke, le minqamulajuqu ayisungulwa ngokwezokwelapha. Alukho ucwaningo olukwazile ukukhombisa ukwanda kwemvamisa yokungajwayelekile noma ukuphuphunyelwa yizisu, noma ukukhulelwa okuningi kwabesifazane abakhulelwa lapho iphilisi limiswa (2). Ngakho-ke kuhle ukumisa iphilisi kusukela ngesikhathi ofuna ukukhulelwa. Ngokufanayo, akulungile ngokwezokwelapha ukuthatha “ikhefu” ngenkathi uthatha iphilisi ukuze kulondolozwe inzalo.

Kwenzeka ukuthi iphilisi, elenza imithetho yokufakelwa ngokuphuma kwegazi (ngokwehla kwamahomoni ekupheleni kwephakethe), inezinkinga zokuvuthwa okufihliwe, okuyinto. izophinde ivele uma uyeka ukuphuza iphilisi. Izimbangela ezivame kakhulu yi-hyperprolactinemia, i-polycystic ovary syndrome (PCOS), i-anorexia nervosa noma ukwehluleka kwe-ovarian ngaphambi kwesikhathi (3).

Okunye okubakhathaza kakhulu abantu besifazane ngephilisi ukuthi kungenzeka libe nomthelela walo ekuvundeni, ikakhulukazi uma liphuzwa ngokuqhubekayo iminyaka eminingi. Umsebenzi wesayensi nokho uyaqinisekisa ngale ndaba.

Ucwaningo (4) olwenziwa ngaphakathi kohlaka lwe-Euras-OC (uhlelo lwaseYurophu lokugadwa okusebenzayo kwemithi yokuvimbela inzalo ephathwayo) futhi olubandakanya abesifazane abangu-60 abasebenzisa izivimbela-nzalo ezisetshenziswa ngomlomo lubonise ukuthi ngenyanga elandela ukumisa iphilisi, i-000 % yabo yayikhulelwe. Lesi sibalo esihambisana nesokuzala kwemvelo, sivame ukufakazela ukuthi iphilisi aliphazamisi inzalo kanye namathuba okukhulelwa. Lolu cwaningo luphinde lwaveza ukuthi isikhathi sokuthatha iphilisi asibanga namthelela emathubeni okukhulelwa: u-21% wabesifazane abaphuza iphilisi isikhathi esingaphansi kweminyaka emibili bakhulelwa kungakapheli unyaka, uma kuqhathaniswa no-79,3% kwabesifazane ababelisebenzisile. isikhathi esingaphezu kweminyaka emibili.

Uma kungekho ukubambezeleka phakathi kokumisa iphilisi nokuqala kokuhlolwa kokukhulelwa, kuyanconywa nokho ngokuqinile ukuthi ubonane nodokotela wakho wezifo zabesifazane, udokotela ojwayelekile noma umbelethisi ngaphambi kokumisa iphilisi. ukuze kuboniswane ngaphambi komqondo. Lokhu kubonisana, okunconywe yi-Haute Autorité de Santé (5), kuhlanganisa:

• ukuphenywa ngomlando wezokwelapha, wokuhlinza, wokubelethisa
• ukuhlolwa komtholampilo
• i-cervical dysplasia screening smear uma ingaphezu kweminyaka emi-2 kuya kwemi-3 ubudala
• ukuhlolwa kwaselabhorethri: amaqembu egazi, ukucinga ama-agglutinins angajwayelekile, i-serology ye-toxoplasmosis ne-rubella, kanye nokuhlolwa kwe-HIV, i-hepatitis C, B, ugcunsula.
• i-folic acid supplementation (i-vitamin B9)
• ukugoma ukubamba i-rubella, i-pertussis, uma ingekho esikhathini samanje
• ukuvimbela ubungozi bendlela yokuphila: ukubhema, utshwala nokusebenzisa izidakamizwa
