Background: Previous studies highlighted the negative effect of premature progesterone elevation (PE) during IVF cycles on the cycle outcomes. The aim of this study was to assess the validity of progesterone level on hCG day (P4) in the prediction of IVF/ICSI cycles’ outcome. Methods: In a retrospective cohort study, all fresh cycles of 256 patients who underwent IVF or ICSI cycles in 2017 at reproductive endocrinology & infertility unit/ Obg/Gyn department at King Abdulaziz Medical city, Riyadh, Saudi Arabia, were followed up. They were started on gonadotropin medications for ovarian hyperstimulation, followed by serial transvaginal U/S and serum estrogen levels each visit. Patients having 2 or more 18mm follicles were triggered by hCG 10,000 IU and ovum pickup was done 34-36 hrs after. Data were collected on patients’ characteristics [age, BMI infertility type], cycles’ characteristics [number of follicles and endometrium thickness on hCG day, P4 and estrogen levels], rates of pregnancy and pregnancy outcomes. Receiver operating characteristic curve was applied to determine the cut-off of P4 that corresponds with a negative pregnancy test. Logistic regression analysis was used and significance was considered at p - value of ≤0.05. Results: Pregnancy rate in the study sample was 36.7%. The mean P4 level in cycles with negative pregnancy tests was significantly higher than the mean in cycles with positive tests (p = 0.018). After adjusting for confounders, significant negative association between P4 and pregnancy rate was evident (p < 0.03). The optimum trade-off of P4 for prediction of a negative pregnancy test was 1.5nmol/L. This cut-off level had a 59% sensitivity, 51% specificity and 68% positive predictive value and 10% & 15% absolute and relative risk reductions respectively. Cycles with mean P4 of ≥1.5nmol/L were significantly associated with primary infertility (p = 0.011), lower mean BMI (p = 0.009) higher mean estrogen level (p < 0.001), lower live birth rate (p = 0.048), higher abortion rate (p = 0.039), and higher ovarian hyperstimulation rate (p = 0.027). Conclusion: Premature elevation of progesterone level on the hCG day in IVF/ICSI cycles may have adversely impacted the pregnancy rate and pregnancy outcome. The cutoff point of 1.5nmol/L for this P4 was not valid in predicting pregnancy outcomes.

Endometrial thickness and frozen thaw embryo transfer: A prospective study

Published on: 14th October, 2020

OCLC Number/Unique Identifier: 8691248908

Aim and objectives: Endometrial Window of Implantation (WOI) is open in the midsecretory phase wherein the markers of invasion and cell adhesion are manifested .The primary objective was to find out the predictive value of Endometrial thickness and profile as a prognostic factors for embryo transfers during ART. Materials and Methods: Endometrial thickness assessment was performed with grey scale ultrasound on the day of transfer just before thawing the embryos in patients undergoing Frozen embryo transfer cycle after endometrial preparation. Results: The mean age and standard deviation of study population was is 33.26+5.95.Out of 69 patients there was clinical pregnancy in 33 patients , miscarriage in 10 patients and ongoing pregnacy in 23 patients. So the implantation rate was 47.83% (33/69), early miscarriage rate (pregnancy ending before 12 weeks) was 14.49%(10/69) and the ongoing pregnancy rate was 33.33% (23/69). Endometrial thickness < 6 mm had comparable implantation rates but low ongoing pregnancy rates. Conclusion: The ultrasound morphological and vascular grading of endometrial thickness and vascularity is useful to synchronise Day 5 embryo transfer and window and implantation thereby minimizing the loss of good embryos in nonreceptive endometrium.

Application of autologous adipose-derived stem cells for thin endometrium treatment in patients with failed ART programs

Published on: 12th February, 2019

OCLC Number/Unique Identifier: 8012133540

One of the factors of assisted reproduction technology (ART) success is an adequate growth and development of endometrium. At the end of follicular phase of menstrual cycle endometrium reaches its greatest thickness. It is believed that there is a critical limit of endometrial thickness beyond which the implantation of embryo is unlikely or impossible [1-5]. In practice of ART programs ultrasound measurement of endometrial thickness is used to evaluate uterine lining growth. Scientific literature is debatable as to what thickness of endometrium should be considered optimal, some researchers emphasize the negative impact of “thin endometrium” on the success of ART programs [1-12], while others do not agree [6,7,9]. Nevertheless, when endometrial thickness in ART program does not exceed 6 mm the chance of pregnancy occurring is very low (Kumbak B, et al. 2009).

Could metabolic risk factors contribute to the development of cervical cancer?

Published on: 18th December, 2019

OCLC Number/Unique Identifier: 8501565253

The role of human papillomavirus infection as etiological factor for cervical squamous intraepithelial lesions and cervical cancer is well established. However, the presence of this virus is not sufficient condition for developing of cervical cancer. Currently, the contribution of other viral, environmental and host cofactors in triggering of this neoplasm is being investigated. Some metabolic risk factors have been associated with the development of several gynecological cancers such as endometrium, ovary and cervix. However, the mechanisms through which these factors contribute to carcinogenesis are complex and not fully elucidated. Few interventions regarding host metabolic factors have been performed on women at risk of developing cervical cancer. Some specific treatments and or changes in lifestyles could be carried out to avoid or delay progression to this kind of cancer. This paper aims to enlarge and update this topic based on the article ¨Association between components of the metabolic syndrome and degree of cervical squamous intraepithelial lesions in Cuban women¨, with emphasis on possible mechanisms that explain the link between central adiposity, insulin resistance and dyslipidemia with risk of premalignant lesions and cervical cancer.

Abnormal uterine bleeding and severe anemia cause the life-threatening condition

Published on: 22nd November, 2022

The World Health Organisation (WHO) defines anemia as a global public health problem. It is a medical condition in which the number of red blood cells or the hemoglobin concentration within them is below the physiological range. We present a case of a 40-year-old woman with Abnormal Uterine Bleeding (AUB) accompanied by malaise, weakness, and tachycardia. The patient reported heavy menstrual bleeding for the past 14 days. Speculum examination revealed that the bleeding was from the uterus. There were no pathological findings during a gynecological and transvaginal ultrasound examination. A complete blood count performed at the time of her arrival showed a low hemoglobin level of 24 g/L, a low hematocrit level of 7,4%, a mean corpuscular volume of 98,7 fL and a number of red blood cells 0,75 x 1012/L. Due to the severity of the anemia, she was given 6 units of red blood cell transfusion, 2 fresh frozen plasmas and tranexamic acid accompanied with calcium carbonate. The curettage was performed. The pathohistological finding was endometrium in proliferation. Afterward, the hemoglobin level increased to 90 g/L. Their past medical history revealed that she abused alcohol. On an abdominal CT scan, Alcohol-Related Liver Disease (ARLD) was confirmed. We should keep in mind that coagulopathy could be the underlying cause of abnormal uterine bleeding and that anemia must be analyzed for successful treatment. A multidisciplinary approach to anemia caused by AUB is required in cases of severe anemia.

A two-phase sonographic study among women with infertility who first had normal sonographic findings

Published on: 15th December, 2022

Introduction: Sonographic scan tests are real-time procedures but the female reproductive systems are subject to continued changes beyond the mid-menstrual period. Therefore a second test may be useful after mid-menstrual ultrasound tests among women with infertility who first had normal ultrasound tests during the mid-menstrual period. Aim: The aim of this study is to find out whether physiological changes beyond the mid-menstrual period in the female reproductive system could develop into findings that could be missed at the first ultrasound test among women with infertility during mid menstrual period. Method: One hundred and forty (140) women participated in this study, over a period of 12 months. The inter-observer correlations were carried out. The ultrasound test measured the diameters of the endometrium and ovarian follicle. The study was carried out during the mid-menstrual cycle when normal changes are optimal. The subjects were women of childbearing age (18 years - 40 years) with 28 days cycles who were referred from the fertility clinic. Women who had previous pelvic surgery, women on fertility therapy, and women who were unsure of the date were excluded from the study. Only women who met the inclusion criteria were selected for the study. The selection was by convenience sampling method. The women underwent the first phase of the ultrasound test during the mid-menstrual cycle. Those who had ultrasonographic-positive infertility reports were returned to the referral clinic. Only women who had normal ultrasonographic fertility reports were included in the second phase of further ultrasonographic tests. The scans were carried out further for four days for this second phase study and the result was again compared with normal values. (Endometrium Normal range 7.4 mm - 13.5 mm and ovarian follicles normal range 17.4 mm to 23.5 mm). Results: The first phase of the scan showed 108 (77%) of the women had positive infertility results for endometrium and ovarian follicles, while 32 (23%) of the women had a normal ultrasonographic result and were rescanned over days. The findings of the second phase scan showed that 10 subjects (7.30%) showed new abnormalities, Findings were distributed in three sub-groups in this second phase of the study. Sub-group A, 4 (2.67%) had enlarged unruptured follicles, sub-group B, 6 (4.30%) had an endometrial cavity filled with fluid, sub-group C, 22 (15.70%) subjects still had normal scans who may be referred for other studies. Conclusion: Women with infertility who had a normal scan at the mid-menstrual cycle should be followed up with a second-phase ultrasound scan before other tests.
