This review inspects the usage of animal models and the practical solutions of this method for different challenges of endometriosis. The objectives of the study are to determine and compare the histopathology, biomarkers, and development of endometrial lesions in murine homologous and heterologous endometriosis models.

The literature search was performed on PubMed, Scopus, Web Cochrane, and EMBASE from January 1990 to January 2019. Experimental articles in which the establishment of the endometriosis model had been proven through the examination of size, weight, number of implants, adhesion, histologic score, and altered biomarker were eligible for inclusion.

Based on type of induction, articles were categorized into two groups: heterologous-induced method (n=5) and autologousinduced method (n=13). In general, in case of establishing the heterologous induction method is less reliable than the autologous induction method.

Using human endometrial tissues for endometrial inductions is possible in heterologous models under immunosuppression, which is more suitable for therapeutic studies, but time limitation considerations are mandatory for this type of model. Homologous endometriosis inductions cause larger endometrial lesions, biomarkers, and reproduction rate changes similar to those occurring in humans. Similarities make this method more appropriate for pathogenesis and genetic studies and also observe the impact of endometriosis on the next generation. Choosing an appropriate model for the induction of endometriosis is dependent on the purpose of each study.

The current study was conducted on adult male models to assess the impact of the Syzygium aromaticum (clove) extract on male fertility factors and oxidative stress after torsion/detorsion using the intrauterine insemination (IUI) method.

This experimental study was performed on 56 adult male Wistar rats including 28 males and 28 females. The male subjects were randomly assigned to four groups of sham (G1), 4 hours of testicular torsion following a surgical torsion/detorsion (TD/G2), TD treated with the clove extract (4 mg/kg, orally/G3) 30 minutes before detorsion, and healthy subjects treated with the clove extract (4 mg/kg/G4). The levels of blood testosterone and some oxidative stress indices were investigated in the testis tissue. In addition, some sperm parameters were evaluated, including the concentration, motility, and morphology of the sperm. Finally, the fertilization potential of adult female rats was assessed through the IUI method.

The histological evaluation revealed considerable adverse changes in the G2 in comparison with the sham group. The serum levels of testosterone, and glutathione peroxidase, and superoxide dismutase meaningfully reduced in the testis of rats in the G2. In addition, the malondialdehyde level was significantly higher during the ischemia although all the mentioned changes improved in the treated groups. Nonetheless, the sperm quality and fertility power considerably reduced in the G2 compared to the sham group.

The results of the current experimental study demonstrated that the testicular torsion/detorsion has an adverse impact on the testis function and decreases the fertilization potential, and finally, treatment with the clove extract can improve these adverse changes.

Threatened miscarriage is a common disorder in early pregnancy and is seen in 20% of pregnant women. Currently, there is no effective therapeutic solution for this condition. This study aimed to determine the effects of a special food (fried egg with grape molasses) on threatened miscarriage in combination with conventional therapies.

This randomized controlled clinical trial was conducted on 93 pregnant women with mild or moderate vaginal bleeding up to 16 weeks of gestation in two groups. The control group (n = 47) used progesterone 400 mg suppository daily with abstinence from sexual intercourse and physical activity. The intervention group (n = 46) consumed fried eggs with grape molasses and the routine treatment like the control group. The treatment was considered successful if the pregnancy continued up to 20 weeks. Finally, the risk of abortion (miscarriage rate) and the duration of vaginal bleeding were compared between two groups.

The risk of abortion in the control group was about 26% (12 of 45 pregnancies), while in the intervention group, it was 15% (7 of 45 pregnancies). This result was not statistically significant between the two groups (Risk ratio: 0.69, 95% CI: 0.37-1.30, P= 0.197). Additionally, no significant difference was detected regarding the duration of vaginal bleeding between the intervention and control groups (P= 0.699).

There is no significant statistical relationship between the consumption of “fried eggs with grape molasses” and reduction of abortion risk.

One of the most prevalent benign tumors in women is uterine leiomyoma. Large quantities of fluid absorbed during myomectomy may cause serious problems such as volume overload and hyponatremia. The aim was to see how intraoperative oxytocin infusion affected irrigation fluid absorption in individuals having hysteroscopic myomectomy.

50 women between 25-45 years who underwent hysteroscopic myomectomy and had an American Society of Anesthesiologists class I or II were evaluated in this randomized, double-blind clinical trial study. A 250 mL ringer solution containing 15 units of oxytocin was administered at a 125 mL/h in the oxytocin group (group S). In contrast, the placebo group (group P) received 1.5 mL of normal saline in the same amount of Ringer solution. Intraoperative hemodynamic alterations, fluid deficit, decreased hemoglobin, hematocrit, sodium, and albumin levels from baseline, complications, and the incidence of toxicity with the administered solutions were assessed intraoperative and 24 hours later.

Group S had considerably reduced irrigation fluid volume (P=0.021) and volume deficit (P=0.001). The frequency of hypotension in individuals receiving oxytocin did not differ significantly from the placebo group (P=0.26). In group S, serum hematocrit (P=0.036) and sodium (P=0.026) were decreased significantly.

Intraoperative oxytocin infusion during hysteroscopic myomectomy may be associated with reduced irrigation fluid absorption and the problems that come with it. As a result, this approach might decrease the risks associated with high amounts of irrigation fluid being absorbed during hysteroscopic myomectomy.

To evaluate the in vitro fertilization success rate by transferring top- versus low-quality embryos.

This prospective cohort study was conducted on 199 infertile women. Ninety-nine patients underwent an agonist cycle (70 fresh embryo transfer [ET] and 29 frozen ET), and 100 patients received an antagonist cycle (28 fresh ET and 72 frozen ET) in the infertility department of a tertiary university-based hospital between May 2019 and March 2020. The blastocysts classified as AA, AB, and BB, as well as AC, BC, and CC were considered as top- and poor-quality embryos (TQE and PQE). The study outcomes were biochemical and clinical and determined the rate of pregnancy.

The average age of the participants was 32.44±5.25 years old. Women with TQE were significantly younger than those with PQE (31.35±4.97 vs. 34.09±5.27, P<0.001). In addition, the duration of women’s infertility was significantly (P<0.001) correlated with the embryo’s top quality. A positive β-human chorionic gonadotropin was detected in 12.6% (n=25) of women while clinical pregnancy was investigated in 8% (n=16) of them. The fetal heart rate was detected in 7.5% (n=15). Eventually, the clinical (P=0.020) and determined (P=0.030) pregnancy rates significantly differed between two study groups with a higher level in the TQE group.

It seems that TQP transfer should be the first recommendation for infertile women, but when the double-embryo transfer (DET) is needed according to the patient’s condition, she should be informed that the quality of the second embryo may have an adverse impact on pregnancy consequences.

Although ovarian cancer is the sixth most common cancer among women, in most cases, it is not diagnosed until it covers the entire peritoneum. In the present study, it was examined the clinical outcomes of the women with epithelial ovarian cancer (EOC) in stage IIIC-IV treated with neoadjuvant chemotherapy (NACT) and its association with decreased ovarian cancer antigen (CA-125).

In this cross-sectional study, 78 women with EOC (Stage IIIC-IV) who underwent NACT at Imam Khomeini hospital, Tehran, Iran were evaluated. Demographic characteristics, aged at diagnosis, severity and stage of disease, serum CA-125 level, histological type, tumor pathology before and after chemotherapy, overall survival, and recurrence of disease was examined.

In total, 78 women with mean age of 52.83 ± 10.18 (between of 29 to 77) years were evaluated. The majority of the patients had positive initial ascitic fluid cytology for malignancy (68.9%). After surgery, papillary serous was the most common histologic finding (73, 81.1%). CA-125 level post NACT (median of 25 U/mL) was significantly reduced compare to before NACT (median of 980 U/mL; P<0.0001), and the rate of CA-125 reduction was significantly lower in older participants’ ages (r=0.274, P=0.017). Survival time showed a significant and strong negative correlation with the CA-125 levels before (r=-0.363, P=0.003) and after NACT (r=- 0.383, P=0.002). Moreover, there was a significant negative correlation between survival time and chemotherapy courses (r=-0.363, P=0.003) and age (r=-0.474, P=0.000).

The results of this study showed that the clinical outcomes of patients with advanced ovarian cancer can be predicted by a decrease in serum CA-125 levels after NACT.

Newborns with fetal growth restriction (FGR) are at a high risk of prenatal mortality and morbidity compared to infants with appropriate intrauterine growth. The importance of Doppler ultrasound as a non-invasive method for estimating the pulmonary artery pressure (PAP) in newborns and adults has been mentioned in many studies. This study investigated the relationship between peak systolic velocity in pulmonary artery color Doppler and neonatal respiratory outcomes in FGR with abnormal fetoplacental circulation.

In this prospective cohort study, 60 pregnant women with a gestational age of 32-37 weeks were studied in two groups: group I (women with fetus suspected of FGR according to ultrasound assessment) and group II (women with normal pregnancy). All women underwent Doppler ultrasound of pulmonary artery, umbilical artery, middle cerebral artery, and venous ductus. The pick systolic velocity (PSV) of the trunk of the pulmonary artery was evaluated in the fetus of all participants. After delivery, all infants were studied for respiratory outcomes at birth. Finally, variables included gestational age, fetal estimated weight based on Hadlock table, fetal amniotic fluid index, maternal parity, umbilical artery pulsatility index (PI), middle cerebral artery PI, maximum pulmonary artery velocity (PV), umbilical artery to middle cerebral artery index ratio, and the number of infants admitted to the newborn intensive care unit (NICU) due to respiratory distress were compared between two groups.

Our results showed a significant association between pulmonary artery PI in FGR fetuses with abnormal fetoplacental circulation. The rate of early NICU hospitalization of infants in the group I was higher than group II due to respiratory diseases, as well as the need for oxygen and continuous positive airway pressure (CPAP).

Pulmonary artery color Doppler ultrasound can be effective in diagnosing FGR embryos during pregnancy and making the necessary predictions to reduce prenatal mortality and morbidity in these infants.
