[@RanjanKumar-c4j2r]

Ova nahi hormones release karta hai mam ...ova ka layer jo grafian follicles hota oo convert hokar carpus luteum bana hai jo progesterone or estrogen hormone release karta hai...

[@VedicArora-uk9zx]

Follicular cells or granulosa cells release karti hai estrogen and theca cell karti hai androgen (male hormone) which is converted into estrogen by granulosa cell having an enzyme.

[@VedicArora-uk9zx]

Corpus luteum secrete peri peri' P for progesterone E for estrogen R for relaxin And I for inhibin

[@veenakisku5491]

Toh mam ova ke sath sath endometrium v bleed out hota hai menstruation ke form mai , or jaise new ova ready hota hai waise he kya fir se endometrium v ready hota hai ??? But endometrium toh embryo ko aapne andar ly lyta hai jab embryo ko developed karna hota hai

[@MagnetBrainsEducation]

Hi! Thank you for your thoughtful comment! Yes, you are correct! During a menstrual cycle, the endometrium sheds and a new layer is formed in preparation for a new egg. During pregnancy, the endometrium thickens and forms an ideal environment for an embryo to implant and grow. We hope this answers your questions!

Ma'am during pregnancy time ae periods kyu nahi aate

[@VedicArora-uk9zx]

Kyu pregnancy k time per endometrium ki lining shed ni hoti hai isliye kabhi bhi bleeding ni hoti hai.aur voh isliye shed ni hoti hai kyuki corpus luteum progesterone secrete karta hai throughout the pregnancy to maintain endometrium lining.
