Corpus luteum, yellow hormone -secreting body in the female reproductive system. It is formed in an ovary at the site of a follicle, or sac, that has matured and released its ovum, or egg, in the process known as ovulation. The corpus luteum is made up of lutein cells (from the Latin luteus, meaning “saffron-yellow”), which develop immediately following ovulation, when yellow pigment and lipids. Corpus Luteum Female Reproduction. The corpus luteum is remarkable in that it is critically important for reproduction in numerous Corpus Luteum Formation.

Ketan Shrestha, CL formation entails, at a cellular level, intense interactions Benign Conditions of the Ovary. The corpus luteum. The corpus luteum is made from a follicle that housed a maturing egg.

This structure starts to form as soon as a mature egg pops out of the follicle. The corpus luteum is essential for conception. Overview of Corpus Luteum Cyst Corpus luteum cysts are a type of a functional ovarian cyst that occurs when a corpus luteum fails to relapse following the release of an ovum. When linked with pregnancy, it is the most common pelvic mass encountered in the first trimester. At times, the corpus luteum can accumulate with fluid.

The corpus luteum (Latin for “yellow body”; plural corpora lutea) is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A. It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation. The corpus luteum is colored as a result of concentrating carotenoids (including lutein) from the diet and. The corpus luteum, which means yellow body in Latin, is what is left of the follicle after a woman ovulates.

During the follicular phase of a woman’s cycle, several follicles develop under the influence of FSH (follicle stimulating hormone). Each follicle contains an egg. In a typical cycle only one egg will become mature enough for ovulation. The corpus luteum produces estrogen and progesterone.

The progesterone facilitates the regrowth of the uterine lining and inhibits the release of further FSH and LH. The uterus is being prepared to accept a fertilized egg, should it occur during this cycle. The corpus luteum is formed in the ovary and is made up of a cell type called the lutein cell. Lutein cells are granulous cells with a pale cytoplasm that is rich in lipids that will begin to develop and build up fatty lipids and yellow pigment within the lining of the follicle.

This lends the tissue a. The corpus luteum (plural: corpora lutea) is a temporary endocrine structure involved in ovulation and early pregnancy. During ovulation, the primary follicle forms the secondary follicle and subsequently the mature vesicular follicle. At ovulation the follicle ruptures expelling the ovum into the fallopian tube. The corpus luteum (Latin, corpus = body, luteum = yellow) develops from the remains of Graffian follicle after ovulation.

Functions as an endocrine organ (produce progesterone and estrogens) supporting pregnancy and preventing menstruation (loss of the endometrial lining).

  • Holy shit, that is 12 minutes I will never get back and my ears and nerves are drained. No wonder you only have 102 subscribers if this video is any indication.

  • Thank you for posting this! Just found out I have a Corpus luteum cyst on one of my ovaries after ovulating. Hopefully this goes away within 1-3 menstrual cycles! Trying for a baby after 2+ years of infertility. Jesus we trust in You!

    UPDATE: the cyst went completely away on it’s own after my period came:)

  • Thanks!
    Helped a lot..
    U r really good at explaining..btw if u do more videos on embryology as well as abdomen that’d be really helpful..
    #..idk if u r a medico though

  • veryy helpful video��…. understood very clearly..can you please explain embryonic development too please…including blastulation implantation amd other topics like placenta and all pleasee

  • Absolutely crisp yet in depth presentation. Such amazing animation. I dont think ill ever read my books if i wanna brush up my concepts on oogenesis.

  • Maam… Plz make other videos on this embryology topic, so that we B SC student can gain benifit. It was exclusively wonderful as this contains the whole concept. Thanks for making such wonderful video. But finally one request that keep making such videos

  • @ 5:14 isn’t it the secondary oocyte that is shed from the ovary? bcz the ovum is formed after fertilization if im not wrong..im confused..:(

  • Thnku sir i have so much doubt that I m > 6 month pregnancy with luteum corpus n no fetal pole n yolk sac….this my second pregnancy n….plz sir plz give me a ans my pregnancy is ok or not?

  • why are we saying that nucleus is absent in the ovum..infact nucleus consists of genetic material..nd if it is absent then variations may not come…i m bit confused��
