In the follicular phase, the biochemical and physiological events (secretions of LH, FSH and estrogen) support the growth of the follicle (the cell complex that surrounds and nurtures the egg) in the ovary and build up the lining of the uterus to receive a fertilized egg. At mid-cycle, when the egg is ready, a chemical signal -- a surge of LH and FSH -- tells the ovary to release the egg. This stage is called ovulation, and is the optimum time for fertilization to take place. The follicular phase basically is a cluster of cells that surrounds an egg and prepares it for release into the human female reproductive tract.
What else can I help you with?
Palpable uterine artery pulsation?
Palpable uterine artery pulsation refers to a medical doctor feeling the uterine artery when your heart beats. Studies are underway to determine if a palpable uterine artery is a possible indicator of early pregnancy.
What is palpable uterine artery pulsation?
It means you can feel the pulses of blood flowing through your main artery in the uterus (uterine artery) just by touching the area where the uterine artery passes through.
Were Does Hair Come From?
From the hair follicle.
Name for a ruptured follicle?
I think it's called Corpus Luteum
My Dr found during hysterectomy surgery and commented that I have enlarged uterine arteries what does this mean?
Gynecologists often tell women after exploratory surgery or hysterectomy that the blood supply to their uterus consisted of large veins and arteries. It is not a problem or concern, there is no reason to worry about it.
What happens to the egg follicle the ovary?
A mature follicle will be released during ovulation and travel to the uterus. If is it fertilized, then it will implant in the uterine wall. If it does not then it will be passed out of the body during the menstrual cycle.
What are the two effects a peak in LH has on the follicle?
A peak in luteinizing hormone (LH) triggers ovulation, leading to the release of a mature egg from the follicle. Additionally, it stimulates the transformation of the ruptured follicle into the corpus luteum, which then produces progesterone to prepare the uterine lining for potential implantation of a fertilized egg.
What hormones influences the follicle to become corpus luteum?
The transformation of the follicle into the corpus luteum is primarily influenced by luteinizing hormone (LH). After ovulation, LH stimulates the remaining cells of the ruptured follicle to differentiate into luteal cells, which form the corpus luteum. Additionally, follicle-stimulating hormone (FSH) plays a supportive role in the early stages of follicle development leading up to ovulation. The corpus luteum then produces progesterone and estrogen, which are essential for maintaining the uterine lining during the early stages of pregnancy.
What happens to the lining of the uterus when the follicle changes into a yellow body?
As the follicle grows it produces certain hormones which reactive uterine wall to become thickened and to be supplied with a lot of blood. This change is a kind of preparation of the uterus to receive the fertilized egg and to provide for the development of the future embryo
What structure releases progesterone to increase the vascularity of the uterine lining?
The corpus luteum, formed from the remnants of the ovarian follicle after ovulation, is the structure that releases progesterone to increase the vascularity of the uterine lining. Progesterone helps prepare the uterus for potential embryo implantation by promoting a rich blood supply to the endometrium.
What is the difference between ovarian and uterine cycle?
The ovarian cycle refers to the changes that occur in the ovaries, including follicle development, ovulation, and corpus luteum formation. The uterine cycle, on the other hand, involves the changes in the endometrium lining of the uterus in preparation for implantation of a fertilized egg. The ovarian cycle is responsible for the production of eggs, while the uterine cycle provides a suitable environment for embryo implantation.
Is it worth pursuing IUI with just one 20mm follicle and a lining of 6?
Pursuing IUI with one 20mm follicle and a uterine lining of 6mm may not be ideal. While the follicle size suggests ovulation could occur, the endometrial lining is generally considered thin for optimal implantation. It's essential to consult with a fertility specialist to evaluate the overall situation and consider potential adjustments to improve the chances of success.
Which region of the uterine tube captures the ovum?
During ovulation, the ovum is released due to rupture of the Mature or Graafian follicle. The unfertilized ovum is captured by the fimbria of the tuba uterina or oviduct at the infundibulum region.
What are the changes that take place during the menstrual cycle from day 1-4 to unfertilized egg in ovary?
During days 1-4 of the menstrual cycle, menstruation occurs as the uterine lining sheds due to the decline of hormones like estrogen and progesterone from the previous cycle. As the cycle progresses, the follicles in the ovaries begin to develop under the influence of follicle-stimulating hormone (FSH). By the end of this period, one follicle becomes dominant and continues to mature, while others undergo atresia. An unfertilized egg remains in the dominant follicle, and as estrogen levels rise, the uterine lining begins to thicken in preparation for a potential pregnancy.
What are the stages of follicle development?
Follicle development occurs in several stages: primordial follicle, primary follicle, secondary follicle, preantral follicle, antral follicle, and mature (Graafian) follicle. Each stage involves specific changes in the follicle and oocyte as they mature towards ovulation.
How is the oocyte transported from the ovary to the uterus?
Near the ovary you have fimbriated end of the Fallopian tube. It take in the ovum inside. Then you have cilia in the Fallopian tube to push the ovum towards the uterus.
What is A mature ovum in its sac sometimes called is it an oocyte or a primary follicle or a graafian follicle or an ovarian follicle?
graafian follicle
