ABSTRACT

BACKGROUND: Omega-3 fatty acids promote fertility in males and females and constitute an important factor in the normal development of the fetus. OBJECTIVES: We investigated the effect of omega-3 supplements during ovulation induction treatment in women with polycystic ovary syndrome (PCOS)-related infertility. METHODS: A randomized, double-blind study was conducted for 60 treatment cycles in 34 women with PCOS-related oligo/anovulation referred to the fertility clinic at the Bikur Cholim/Shaare Zedek Medical Center in Jerusalem, who underwent ovulation induction with clomiphene citrate (50 mg). Seventeen women (mean age 33.9 ± 0.9 years) received omega-3 supplements (3 × 600 mg/day) and 17 received placebo capsules (mean age 32.7 ± 0.9 years) for a maximum of two cycles. We recorded their characteristics and data from their serial hormonal blood tests and ultrasound examinations. We also conducted both univariate and multivariate analyses. The primary endpoint was conception. RESULTS: There were clinical pregnancies in 8/30 (26.7%) treatment cycles for women receiving omega-3 supplements versus 4/30 (13.3%) cycles with placebo. Among overweight/obese women (body mass index [BMI] 25-35), there were clinical pregnancies in 8/27 cycles (29.6%) versus 1/19 (5.3%) with placebo (P < 0.04). For overweight/obese PCOS women, omega-3, lower BMI rates, and higher values of the endometrium's thickness increased the odds of becoming pregnant. No harmful side effects from the omega-3 treatment were reported. CONCLUSIONS: Omega-3 supplements demonstrated beneficial effects for fertility in women diagnosed with PCOS. Among the overweight/obese participants, the increased clinical pregnancy rate was significant.

ABSTRACT

PURPOSE: To report outcome of planned oocyte cryopreservation (POC) in the first 8 years of this treatment in our center. METHODS: A retrospective study in a university-affiliated medical center. RESULTS: A total of 446 women underwent POC during 2011-2018. Fifty-seven (13%) women presented to use these oocytes during the study period (until June 2021). POC was performed at a mean age of 37.9 ± 2.0 (range 33-41). Age at thawing was 43.3 ± 2.1 (range 38-49). A total of 34 (60%) women transferred their oocytes for thawing at other units. Oocyte survival after thawing was significantly higher at our center than following shipping to ancillary sites (78 vs. 63%, p = 0.047). Forty-nine women completed their treatment, either depleting their cryopreserved oocytes without conceiving (36) or attaining a live birth (13)-27% live birth rate per woman. Only one of eleven women who cryopreserved oocytes aged 40 and older had a live birth using thawed oocytes. CONCLUSION: Women should be advised to complete planned oocyte cryopreservation before age 40, given low success rates in women who underwent cryopreservation at advanced reproductive age. In this study, oocyte shipping was associated with lower survival rate. These findings may be relevant for women considering POC and utilization of cryopreserved oocytes.

ABSTRACT

Mammalian oocyte quality reduces with age. We show that prior to the occurrence of significant aneuploidy (9M in mouse), heterochromatin histone marks are lost, and oocyte maturation is impaired. This loss occurs in both constitutive and facultative heterochromatin marks but not in euchromatic active marks. We show that heterochromatin loss with age also occurs in human prophase I-arrested oocytes. Moreover, heterochromatin loss is accompanied in mouse oocytes by an increase in RNA processing and associated with an elevation in L1 and IAP retrotransposon expression and in DNA damage and DNA repair proteins nuclear localization. Artificial inhibition of the heterochromatin machinery in young oocytes causes an elevation in retrotransposon expression and oocyte maturation defects. Inhibiting retrotransposon reverse-transcriptase through azidothymidine (AZT) treatment in older oocytes partially rescues their maturation defects and activity of the DNA repair machinery. Moreover, activating the heterochromatin machinery via treatment with the SIRT1 activating molecule SRT-1720, or overexpression of Sirt1 or Ezh2 via plasmid electroporation into older oocytes causes an upregulation in constitutive heterochromatin, downregulation of retrotransposon expression, and elevated maturation rates. Collectively, our work demonstrates a significant process in oocyte aging, characterized by the loss of heterochromatin-associated chromatin marks and activation of specific retrotransposons, which cause DNA damage and impair oocyte maturation.

ABSTRACT

RESEARCH QUESTION: Why are women who face poor prognoses for success in assisted reproductive technology (ART) treatment choosing to pursue procedures using their own eggs, despite receiving information that their chances of success are very low. DESIGN: Cross-sectional study based on an anonymous questionnaire distributed to women aged between 43 and 45 years, undergoing ART using their own oocytes, at six public outpatient fertility clinics and three public in-hospital IVF units in Israel between 2015 and 2016. The main outcome measure was personal estimation of chance to achieve a live birth after the current ART treatment cycle and the cumulative estimated rate after all the treatment cycles the patient intended to undergo. RESULTS: Response rate was 70.0%, with 91 participants of mean age 43.8 ± 0.7 years. Participants estimated their delivery rates after the next ART treatment cycle at 49.0 ± 31.8% (response rate 93.4%) and their cumulative delivery rates after all the ART treatments they would undergo at 57.7 ± 36.3% (response rate 90.1%). This is significantly higher than the predicted success rates of 5% and 15%, respectively (both P < 0.001), which are based on national register data. Nearly one-half of patients rated themselves as having a better than average chance of conception (47.3%). CONCLUSION: Women do not pursue futile treatments because they lack information. Despite being informed of the low success rates of conception using ART treatments, many patients of advanced maternal age have unrealistically high expectations from ART, essentially ignoring their estimated prognosis when deciding on treatment continuation. Future work should examine the psychological reasons behind continuing futile fertility treatments.

ABSTRACT

OBJECTIVE: The study aimed to assess whether sub-endometrial contractility is reduced by the use of intramuscular (IM) progesterone. DESIGN: This is a randomized clinical trial. Patients assigned to a medicated day 5 frozen embryo transfer (FET) were randomly allocated to "vaginal progesterone" or "IM progesterone": patients randomized to the vaginal arm were treated with 200 mg micronized progesterone 3 times daily while patients randomized into the IM progesterone arm were treated with a single daily injection of 50 mg progesterone in oil. The main outcome measure was the number of sub-endometrial contractions (waves) per minute 1 day before a blastocyst embryo transfer. RESULTS: Thirty-four patients were enrolled. The progesterone serum concentration was significantly higher in patients using the IM progesterone (85.2 ± 50.1 vs. 30.3 ± 11.2 nmol/L, respectively) but this did not translate into a lower sub-endometrial contractility (2.4 ± 4.8 vs. 1.4 ± 1.1 contraction/min, respectively). Clinical pregnancy rates were comparable between groups. The number of sub-endometrial waves was significantly lower among pregnant patients (p = 0.02). CONCLUSIONS: The use of IM progesterone in medicated FET cycles does not reduce the sub-endometrial activity compared to vaginal progesterone administration. Our data support a poor clinical pregnancy outcome with high wave activity, regardless of the progesterone mode.

ABSTRACT

Anti-Mullerian hormone (AMH), secreted by immature testicular Sertoli-cells, triggers the regression of male fetal Mullerian ducts. During puberty, AMH is downregulated by intratesticular testosterone. In females, AMH is secreted from granulosa cells of immature ovarian follicles from late prenatal life until menopause; serum concentration is 5-20 times lower in females than in males through lifetime. In boys, AMH determination is useful in the clinical setting as a marker of Sertoli cell function. Serum AMH is low in infants with hypogonadotrophic hypogonadism (and increases with FSH treatment), in patients with primary hypogonadism from early postnatal life and in Klinefelter syndrome from midpuberty. In boys with nonpalpable gonads, AMH determination is useful to distinguish between cryptorchidism and anorchism, as well as differentiating the dysgenetic causes of disorders of sexual development from those due to defective androgen synthesis or action. AMH can be used as a marker of sertoli/granulosa cell tumors and primary ovarian insufficiency in girls with delayed puberty, Turner Syndrome and after treatment with gonadotoxic agents.

ABSTRACT

OBJECTIVE: To determine whether the decrease in AMH levels during ovarian hyperstimulation for IVF occurs in patients with polycystic ovary syndrome (PCOS) and patients with low ovarian reserve (LOR), as in normal cycling women. STUDY DESIGN: A cohort of 22 infertile patients treated in a single tertiary center with a GnRH-antagonist short protocol for IVF were prospectively included and divided into three groups: PCOS with hyperandrogenism (n=7), LOR (n=8) and control (n=7). Serum AMH levels were measured before and during FSH treatment, on the day of HCG administration, at the mid-luteal phase, and 14 days after embryo transfer. The three groups were compared using an ANOVA model in the case of continuous data and with Fisher's exact test when the data were discrete. RESULTS: In the PCOS group, AMH levels increased at the beginning of the stimulation, but later decreased, until the mid-luteal stage. In the other two groups, AMH levels decreased throughout ovarian stimulation until the mid-luteal stage. In all groups, AMH levels returned to baseline levels two weeks after HCG administration, regardless of treatment outcome (pregnancy or not). CONCLUSIONS: AMH levels decline during controlled ovarian hyperstimulation with a GnRH-antagonist short protocol in women with low and normal ovarian reserves. In contrast, in women with PCOS, an increase in AMH levels precedes this decline. These findings may support the hypothesis that androgens may play a role in AMH regulation in women.

ABSTRACT

Chorangiocarcinoma is the name designated to a chorangioma with trophoblastic proliferation manifesting increased proliferative activity. Only 3 such cases have been published so far. Other studies challenged this entity by demonstrating that proliferation of the trophoblast around chorangioma is a common phenomenon. We present a case of a unique vascular lesion in a term placenta with a malignant trophoblastic component. Microscopic examination of a well-demarcated placental mass revealed a chorangioma with multiple nodules composed of pleomorphic cells displaying focal multinucleation, large areas of necrosis, and high mitotic activity. Immunohistochemical stains of these cells were strongly positive for pancytokeratin and the beta subunit of human chorionic gonadotropin and focally positive for HSD3B1. There was no invasion of the basement membrane, and no free-floating tumor cells in the intervillous space. No evidence of metastasis was found on follow-up of the mother and newborn. It is concluded that the tumor presented herein, displaying a histologically unequivocal malignant trophoblastic component in a benign chorangioma, is a true chorangiocarcinoma, and should be included within the category of gestational neoplasia as a tumor closely related to choriocarcinoma.

ABSTRACT

OBJECTIVES: Most patients with cystic fibrosis (CF) have pancreatic insufficiency; however, 15% of the patients are pancreatic sufficient (PS). Several laboratory tests have been developed to distinguish between pancreatic insufficiency and PS. The gold standard to determine pancreatic function apart from direct pancreatic stimulation test is the 72-hour fecal fat excretion, expressed as coefficient of fat absorption (CFA). The aim was to test the correlation between 2 other tests, fecal elastase-1 and serum immunoreactive trypsinogen (IRT), as compared with fecal fat excretion. PATIENTS AND METHODS: 21 patients with CF-PS performed the 3 tests of fecal fat excretion, fecal elastase-1, and IRT. Correlation between the tests was evaluated by the kappa statistics test, sensitivity and specificity, and positive and negative predictive values. RESULTS: CFA was abnormal in 5 patients, elastase was <200microg/g in 4 patients, and IRT was <20 ng/mL in 2 patients. The correlation between CFA and IRT was negative(kappa=-0.154), and between CFA and fecal elastase-1 was poor (kappa=0.213). The sensitivity, specificity, and positive and negative predictive values of IRT versus CFA were 0%, 88%, 0%, and 78%, and for fecal elastase-1 were 40%, 81%, 40%, and 81%, respectively. CONCLUSIONS: In CF-PS, poor correlation was found between IRT, fecal elastase-1, and CFA, therefore neither fecal elastase-1 in the stool nor IRT in the serum reaches the sensitivity or the specificity of the fecal fat excretion. Thus, fecal fat excretion is required in patients with CF for evaluation of pancreatic function.
