Clinical Trial Summary

The incorporation of ovarian reserve tests in IVF management started after initial publications indicating a potential role for basal FSH in predicting pregnancy outcome after IVF and in counseling patients (1,2). Since these first publications, a large body of additional work on basal FSH and several other tests has been published, often with inconsistent findings on the magnitude and direction of the predictive effect. (3). Level of basal FSH at the start of IVF, in patients aged younger than 40 years, was shown to predict an oocyte yield by several authors, but wasn't related to pregnancy or implantation rates. (4).

Social egg freezing refers to the cryopreservation of mature oocytes on an elective basis for the purpose of delayed childbearing. Many women now have a solution to "bridge the gap between reproductive aging and readiness to have children. Assessment of ovarian reserve enables estimation of the remaining egg pool and can be compared with other women her age. Ovarian reserve tests aim at identifying women at risk of hypo or hyper response to ovarian stimulation: it can possibly detect reproductive lifespan and approximate menopausal timing, assist in counseling family planning and to optimize ovarian response whilst minimizing risks (5).

In Israel, retention of fertility for non-medical reasons is offered for women who have reached the age of 30, but have not yet reached the age of 41. These women may undergo up to 4 retrievals or until 20 eggs are obtained (whichever occurs earlier). The 2022 Health Services, decided to include, for the first-time, to cover cryopreservation for women with a diminished ovarian reserve (6). This unique population is currently addressing our clinic in order to preserve fertility. One of the criteria for coverage entitlement is elevated day 3 FSH level.

The tests used for assessing ovarian reserve include basal day -3 follicle stimulating hormone (FSH, introduced in 1998). Clomiphene citrate challenge test (CCCT, 1989), gonadotropins releasing - hormone agonist stimulation test (GAST, 1989), Inhibin -B (1997), antral follicle count (AFC, 1997) and antimullerian hormone (AMH, 2002.) (7) Measurement of basal FSH is relatively inexpensive, imposes no major burden on the patient, and is widely used in assisted reproductive technology programs.

Follicular fluid provides a very important microenvironment for the development of oocytes. It is reasonable to think that some biochemical characteristics may play a critical role in determining oocyte quality and the subsequent potential to achieve fertilization and embryo development. Components may also provide information on metabolic changes in blood serum, as the circulating biochemical milieu may be reflected in it's composition .

In our current research we wish to assess cycle yield as related to basal FSH level among women diagnosed as having a low ovarian reservoir and were acknowledge as eligible for oocyte cryopreservation coverage. We also would like to measure hormonal level like LH, FSH, Perlakan ,in a follicular fluid after the oocyte retrieval in order to asses the microenvironment .

Description:

As a routine monitoring, blood sample is drawn in the early follicular phase (day 3 ). FSH will be documented at this point, prior to IVF cycle initiation. Following this point the treatment will follow routine monitoring including Estradiol measurement, progesteroen measurement and an ultrasound.

Follicular fluid collection: After the laboratory licked the eggs follicular fluid will be aspirated and collected.

The database will include in addition : demographic variables (age, BMI, background morbidities , parity , menstrual parameters ) , number of follicles documented by US ,number of oocytes retrieved number of metaphase II oocytes

Inclusion criteria-

• Ages 30 -41

• Patients who undergo fertility preservation

• Patients with a low ovarian reservoir Exclusion criteria-

• Women with a medical indication for preservation

• Women with a single ovary

• Women planned to undergo in vitro fertilization STATISTICAL ANALYSIS - Descriptive statistics will be used to analyze demographic variables. Correlation coefficients will be used to which evaluate basal FSH , oocyte yield and follicular fluid content . All data will be anonymized prior to data extraction and analysis.

BUDJET- All the laboratory data and ultrasound monitoring are fully covered by the Ministry of Health . Data extraction and analysis will be performed by the IVF unit physicians
