简要总结
Women with a severely diminished ovarian reserve and monofollicular growth are at a higher risk of premature ovulation as well as poor quality oocytes. Our group showed previously that women with severely diminished ovarian reserve benefit from receiving the final oocyte maturation at smaller follicle sizes in terms of reducing the risk of premature ovulation and finding mature oocytes even out of small size follicles.
Adding the measurement of the follicular volume at the time of final oocyte maturation might provide more information on the proper timing of trigger administration compared to the follicular size alone, hormonal profile as well as previous stimulation attempts. Setting a cutoff value of follicular volume for trigger might help to avoid premature ovulation and possibly increase the chances of ending up with a euploid embryo.

研究组 & 干预措施
The study population is the infertile patients seeking IVF treatment in ART fertility clinics of Abu
Recruited patients will be stimulated in a antagonist protocol with the use of Pergoveris as gonadotropin with a starting dose of 450 IU. The antagonist will be started on day 5 of the stimulation. Patients will be triggered according to clinical standard protocol for poor ovarian reserve patients when the leading follicle reaches 15 mm (2). The only additional measure will be the measurement of the follicle volumes on the day of trigger and before oocyte pick up procedure. This will be performed at the same time as the pre oocyte pick up ultrasound prior to the patient admission to the recovery room for preparation. The ultrasound that will be used already has a pre build program that calculates the follicular volume automatically and hence not extending the ultrasound time. Oocyte pickup will be performed the same way as per the SOP of the clinic for the patients who have less than 7 follicles on the day of the ovum pickup i.e. each follicle will be punctured, aspirated and then flu
干预措施: transvaginal Ultrasound (Other)

时间窗: 1 year
The objective of this study is to evaluate the relationship between follicular volume at the time of trigger and oocyte maturity in patients undergoing assisted reproductive techniques, specifically those with fewer than four follicles of at least 11 mm in size. This study aims to determine whether follicular volume just before trigger is a significant predictor of oocyte maturation. By focusing on this specific patient group, the study seeks to provide insights that could inform treatment strategies and improve outcomes in assisted reproductive technology.
