“…Even age does not critically influence oocyte maturation rates based on our findings. These findings partially agree with a prior study at our institution ( Cortés-Vazquez et al ., 2021 ). Additionally, our previous experience could only reflect the patients’ outline corresponding to low ovarian responders.…”

“…Previous experience shows a negative influence of progesterone in oocyte maturation (Cortés-Vazquez et al, 2021;Salehnia & Zavareh, 2013). So it is reasonable to assess the impact of progesterone levels on HCG day on the oocyte maturation process.…”

Objective Does progesterone levels on hCG day influence maturation rates and number of mature oocytes during ovarian stimulation for IVF/ICSI cycles?. Methods A retrospective, observational, analytic, cross-sectional and cohort study was performed at the Reproductive Endocrinology Department of the Centro Médico Nacional 20 de Noviembre in Mexico City between 2015 to 2020. All female patients underwent an ovarian stimulation cycle for IVF/ICSI, either with a mild or conventional stimulation protocol. Patients were classified according to their progesterone levels, Group 1 <1.5ng/ml and Group 2 >1.5mg/ml. A Spearman Rho test, a simple linear regression model, a Principal Component Analysis and a Student’s T-test, were performed. Results A total of 600 patients were included. The overall results showed that there is a positive correlation between the number of retrieved, mature oocytes and progesterone levels on HCG day. After the Principal Component Analysis we observed that poor ovarian responders had the lowest maturation rate and number of mature oocytes. While the Student’s t test showed that progesterone levels beyond 1.5ng/ml are associated to a higher number of mature oocytes but not a better maturation rate. Conclusions Higher serum progesterone levels are associated with increased retrieved and mature oocytes in high responders. At the same time, higher progesterone levels in lower responders are not associated with optimal ovarian response.

“…The application of short focused U/S protocols helps to diagnose diseases of lower extremities, aorta, pulmonary arteries, atherosclerotic changes in vessels (Balakhonova et al, 2022). The development of supplementary reproductive technologies made U/S a key method in the evaluation of ovarian syndrome, as well as the control method in ovary paracentesis with ovum collection for IFV and monitoring of the patient's condition after the embryo transfer into the uterine cavity (Cortés-Vazquez et al, 2021). The absence of radiation exposure resulted in the fact that U/S method is the most sought-after for (Lees et al, 2022).…”

Relevance. For more than 100 years, medical practice has used imaging methods to observe pathological changes localized in the human body. The first method was radiography, which became popular among doctors, but later it turned out that high radiation exposure increases the incidence of tumor diseases, which is why standards for permissible radiation doses were developed for patients and radiologists. The introduction of radiocontrast agents also had contraindications that should be taken into account. Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and angiography methods have significantly increased the diagnostic capabilities of instrumental methods. The purpose of this review is to analyze the advantages and disadvantages of modern imaging methods in medicine. Methods. To achieve the purpose of the review, a literature search was conducted in Google Scholar and PubMed databases. Results. 1) The main indication for the X-ray method is visualization of bone structures. 2) X-ray contrast methods are optimal for studying hollow organs and blood vessels. 3) The advantage of MRI is the ability to visualize soft tissue well. 4) CT helps to reconstruct the spatial architecture of organs. 5) Ultrasound allows you to observe the condition of the embryo and fetus, as well as internal organs.
