If the follicle is not yet mature and ovulates, can it still be pregnant?
Why can my follicles only grow up to 16 or 17mm and then drain?
Can an undeveloped follicle be conceived successfully after ovulation?
Today with these questions, let's understand the small follicle ovulation, and why the follicles do not grow up!
What is small follicle ovulation?
Small follicle ovulation, i.e. the dominant follicle has not matured before it has ovulated, is found in the process of ultrasound monitoring ovulation.
General studies have suggested that the average of the 3 diameter lines of the dominant follicles ≥ 18 mm for mature follicles.
Various literature reports indicate the average of the three diameter lines of follicles for ovulation of small follicles
The vast majority of patients with small follicle ovulation have regular menstrual performance, normal luteal function, and no obvious abnormalities in the level of basal hormones, but the released follicles are stunted.
Follicular dysplasia causes the ability of egg cells to conceive over the dominant follicle to decline, causing infertility.
Why doesn't it grow up?
FSH is ineffective
The most direct cause of the follicle not rising is the lack of FSH potency.
FSH is one of the six tests of hormones, Chinese called follicle maturation hormone, and its name is enough to illustrate its role. FSH is secreted by the pituitary gland, which sends signals to follicular granule cells and activates the CYP19A1 gene, a move that activates aromatase and promotes testosterone metabolism into estradiol.
To stimulate follicle development, the quickest way is to hit FSH, commonly known as urine promotion, which is a clinical ovulation promotion program (urinary promotion refers to the extraction of FSH from the urine of menopausal women).
Of course, this fertility solution only solves the immediate need, but it cannot restore the follicle-stimulating effect of your own FSH from the root.
To make FSH better promote follicle maturation, we need to do 3 points.
1. Improve the transmission efficiency of FSH
2. Lower the level of insulin
3. Reduce the level of inflammation
After finding these three points, we can improve our daily conditioning in a targeted manner.
What is the difference between large and small follicles?
The follicle fluid of the large follicle is more abundant, and more estrogen can be produced during the ovulation period to act on the endometrium and fallopian tubes, and the corpus luteum cell content formed by the large follicle after ovulation is more than that of the small follicle, and the luteal function of the large follicle is better than that of the small follicle, so the large follicle produces more estrogen after ovulation to regulate the endometrium and prepare the embryo for implantation. Large follicles provide more "nutrients" for implantation of fertilized eggs.
How is small follicle ovulation diagnosed?
In order to determine the specific time of follicle rupture and dynamically monitor the development status of follicles, vaginal B ultrasound combined with urine LH dipsticks is currently the best way to diagnose ovulation in small follicles.
Ultrasound monitoring of ovulation is the only way to visually understand the morphological changes of the follicle from the outside of the body, and it is also possible to monitor whether ovulation occurs or if there is an unruptured follicle flavinylation syndrome (LUFS).
Urine LH dipstick can quickly and accurately predict the time of ovulation, and is economical, harmless, convenient, if the urine measurement of LH peak, ovulation occurs within 14 to 26 hours.
