Abstract

Background: Heterotopic abdominal pregnancy is a rare entity which poses unique management challenges.
Case: A 24-year-old Gravida 1 woman with history of two years infertility and treatment with clomiphene citrate presented with acute right lower quadrant abdominal pain. Heterotopic abdominal pregnancy was recognized at 16 weeks gestation by transvaginal ultrasound scan. We aimed to remove ectopic pregnancy with prevention of maternal complications and preservation of intrauterine pregnancy (IUP). Surgical removal of the ectopic fetus and placenta was done. Abdominal pregnancy removed successfully without intra- or post-procedural complications but the IUP was aborted spontaneously on the second postoperative day.
Conclusion: Gynecologists should consider the possibility of heterotopic pregnancy following ovulation induction with clomiphene citrate which is increasing in recent years. A high index of suspicion to heterotopic pregnancy may be followed by a nonsurgical approach safely and affectively if they are clinically stable and the abdominal pregnancy is recognized early in gestation.

Abstract

Background: Unovulation is the most common cause of infertility. The first line oral treatment has been clomiphene citrate. Another anti-estrogen used for ovulation induction is tamoxifen. Many unovulatory infertile women are resistance to anti-estrogens and need another treatment. Alternative treatments are aromatas inhibitors.
Objective: This study was designed to compare the effectiveness of clomiphene, tamoxifen and letrozole in ovulation induction outcomes in isolated non PCOS unovulatory patients.
Materials and Methods: 150 unovulatory infertile women who had isolated non- polycystic ovarian syndrome (PCOS), randomized to 3 groups. Group A received clomiphene 50 mg to maximum 150 mg for 5 days, Group B received tamoxifen 10mg to maximum 30 mg for 5 days, Group C received letrozole 2.5 mg for 5 days, to maximum 7.5 mg until ovulation was induced. If ovulation failed to occur with 5 days treatments, drug continued for 7 days. Treatment has been stopped if they became pregnant or if patient didn’t ovulate with maximum dose for 7 days (resistant to treatment) or failed to concept after six months despite ovulation (failure of treatment). Main outcome measures were: number of mature follicles, endometrial thickness, pregnancy rate, multiple pregnancy rate, live birth and miscarriage.
Results: Overall ovulation rate was 60 (73.4%), this rate in group A was 39 (78%), in group B it was 24 (68%) and in group C was 37 (74%). Pregnancy rate in groups A, B and C were, 32 (64%), 20 (40%), and 25 (50%) respectively, and live birth rate was 22 (44%) in A, 17 (34%) in B and 21 (42%) in C. Miscarriage rate with clomiphene was 10 (20%) while this was 3 (6%) in tamoxifen and 4 (8%) in letrozole group (p=0.05). One twin pregnancy was occurred with clomiphene and one with tamoxifen, while all pregnancies with letrozole were singleton.
Conclusion: Because of higher pregnancy rate with clomiphene citrate than tamoxifen and letrozole, Clomiphene citrate is still the first-line therapy for ovulation induction. Surprisingly, pregnancies after tamoxifen and letrozole have lower miscarriage rate than clomiphene.

Abstract

Background: Different protocols are used for controlled ovarian hyper stimulation (COH), but the optimal method has not yet been determined.
Objective: The aim of this study was to compare the outcome of controlled ovarian stimulation (COS) using clomiphen citrate (CC) plus HMG versus CC plus rFSH in intra uterine insemination cycles (IUI).
Materials and Methods: 144 women with unexplained or male factor infertility undergoing IUI cycles were randomized (72 patients in CC plus rFSH group and 72 patients in CC plus HMG group) and included in this single blind study from October 2006 to June 2010. The primary outcomes were clinical and ongoing pregnancy rates. The number of dominant follicles, mean of follicular size, endometrial thickness on the day of HCG administration, total dose of gonadotropins and duration of stimulation with gonadotropins were secondary outcomes.
Results: Clinical and ongoing pregnancy rates were not significantly different in the two groups .There was a significant higher multiple pregnancy rate in CC plus rFSH group (33.3%) versus CC plus HMG group (12.5%; p<0.005). There were no statistically significant differences in the secondary outcomes between the two groups.
Conclusion: According to our results it seems that CC plus HMG is a more suitable and cost-effective regimen than CC plus rFSH in IUI cycles in patients with unexplained or male factor infertility.

Abstract

Background: Intrauterine Insemination (IUI) remains the first thought of infertility treatment.
Objective: To compare the stimulation effects and Pregnancy rate (PR) outcomes of two ovulation induction (OI) medications, human-derived menopausal gonadotrophins (hMGH), Merional (MER), and recombinant follicular stimulating hormone (rFSH), Puregon (PUR), in a cohort of Saudi infertile patients, for better predictability of treatment results.
Materials and Methods: During a 24-month period, 296 women underwent IUI single treatments. PR’s were correlated with the type of stimulation medication that were prospectively and randomly assigned to each patient, and with the number and size of maturing follicles detected on the hCG injection day.
Results: MER and PUR needed comparable number of days (9.26±4.74 and 9.73±6.27 respectively) before follicles were ready for IUI, although the average amount used from MER, 1199.90 IU, was about double that was used from PUR, 621.08 IU. The overall PR in case of PUR however was nearly double that of MER, 13.28% and 7.14% respectively. The best PR, 16.22%, occurred when the follicles matured within 12-13 days. Three follicles of at least 15-mm diameter on the hCG day had better PR’s than one or two, however when the follicles’ diameters were at least 18-mm, PR was significantly higher, (p=0.013).
Conclusion: MER and PUR had comparable stimulation effects; however PUR had noticeably higher PR. The best PR occurred when the follicles matured within 12-13 days. PR in case of three maturing follicles on the hCG day was better than only one or two, and significantly better when their diameters were at least 18 mm.

Abstract

Background: Intracytoplasmic sperm injection (ICSI) is an advanced technique employed in assisted reproductive clinics for treatment of infertile couples. The reproductive endocrinologists try their level best to identify factors that enhance success rate after ICSI.
Objective: To compare estradiol progesterone ratio on ovulation induction day amongst pregnancy outcome groups following ICSI.
Materials and Methods: A cross sectional study was conducted on 323 couples of Assisted Reproductive Clinic in Islamabad from June 2010 till August 2011. Down regulation of females aged 18-40 years with gonadotrophin releasing hormone agonist was followed by calculated stimulation with gonadotrophin injections (COS). Oocytes pickup was done 36 hours after ovulation induction by 16G adapter and double lumen oocyte aspiration needle under general anesthesia. Oocytes were fertilized in vitro, graded and only blastocysts were transferred seven days after ovulation induction. Serum estradiol and progesterone were measured by enzyme linked immuno sorbent assay on ovulation induction day, ratio was compared in three groups of females; no conception with βhCG 5-25 mIU/ml, preclinical abortion with βhCG >25 mIU/ml and no cardiac activity on transvaginal scan and clinical pregnancy with βhCG >25mIU/ml and cardiac activity on transvaginal scan.
Results: Females having high estradiol/ progesterone ratio were able to achieve clinical pregnancy shown by a positive βhCG and cardiac activity on transvaginal scan. These females also had significantly high number of oocytes, endometrial thickness and implantation rate.
Conclusion: A high estradiol/progesterone ratio on the day of ovulation induction predicts the success of intra cytoplasmic sperm injection.

Abstract

Background: The beneficial role of cabergoline as a prophylactic agent to prevent ovarian hyper stimulation syndrome (OHSS) among high-risk patients has been demonstrated in previous studies. But data for its role as a treatment for established severe OHSS is still limited. We represent the treatment results of high dose oral cabergoline in management of six patients after the syndrome is established.
Case: High-dose oral cabergoline (1 mg daily for eight days) was prescribed as an adjuvant to symptomatic treatment for six hospitalized patients with established severe OHSS following infertility treatment cycles. In two cases OHSS resolved rapidly despite the occurrence of ongoing pregnancy.
Conclusion: Considering the treatment outcomes of our patients, high dose cabergoline did not eliminate the need for traditional treatments, but it was a relatively effective and safe therapy in management of established severe OHSS, and prevented the increase in its severity following the occurrence of pregnancy.

Abstract

Background: Despite extensive progress in IVF techniques, one of the most difficult problems is the variability in the response to controlled ovarian hyperstimulation (COH). Recent studies show the effects of individual genetic variability on COH outcome.
Objective: To evaluate the correlation between LHβ G1502A polymorphisms in exon 3 of the LH gene and ovarian response to COH.
Materials and Methods: A total of 220 women treated with a long protocol for ovarian stimulation were studied. Three genotypes of GG, GA and AA were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis.
Results: In total, 34 (17%) patients were poor responders, 154 (77%) were normal responders and 12 (6%) were hyper responders. The most frequent genotype was GA (55.5%) whereas 44.5% of patients showed GG genotype and there was no patient with AA genotype. In total 54.5% of normal responders, 61.8% of poor responders and 50% of hyper responders showed GA genotype.
Conclusion: Our results did not establish a significant relationship between this polymorphism and the ovarian response. Therefore it is still very difficult to use the genotype of patients for prediction of the ovarian response to stimulation.

Abstract

Background: N-acetyl cysteine (NAC) was proposed as an adjuvant to clomiphenecitratefor ovulation induction in patients with polycystic ovary syndrome (PCOS)without clomiphene citrate resistance.
Objective: To evaluate the effect of NAC on pregnancy rate in PCOS patients whowere candidates for intrauterine insemination.
Materials and Methods: In this randomized clinical trial 97 PCOS women aged 18-38 years were enrolled in two groups, randomly. For the case group (n=49), NAC(1.2 gr) + clomiphene citrate (100 mg) + letrozole (5mg) were prescribed dailyfromthe third day of menstruation cycle for five days. The control group (n=48) had thesame drug regimen without NAC. In order to follicular development, GONAL-Fwas injected on days of 7-11 menstrual cycles in all participants. When the folliclesize was 18mm or more, HCG (10000 IU) was injected intramuscular and theintrauterine insemination was performed after 34-36 hr.
Results: There was no significant difference between study groups regarding BMI(p=0.28), FSH level (p=0.66), LH level (p=0.67), mean endometrial thickness(p=0.14), mean number of mature follicles (p=0.20) and the pregnancy occurrence(p=0.09).
Conclusion: NAC is ineffective in inducing or augmenting ovulation in PCOSpatients who were candidates for intrauterine insemination and cannot berecommended as an adjuvant to CC in such patients.

Abstract

Background: Different combination of gonadotropin preparation has been introduced with no definite superiority of one over others in in vitro fertilization (IVF), but individualized regimens for each patient are needed.
Objective: The aim of the present study was to investigate the effect of controlled ovarian stimulation with recombinant- follicle stimulating hormone (r-FSH) plus recombinant-luteinizing hormone (rLH) versus human menopausal gonadotropin (HMG) plus r-FSH on fertility outcomes in IVF patients.
Materials and Methods: This is a randomized clinical trial study that was performed from October 2014-April 2016 on 140 infertile patients with a set of inclusion criteria that referred to infertility clinics in Vali- asr and Gandhi Hospital in Tehran. The women were randomly divided into two treatment groups. The first group (n=70) received rFSH from the second day of cycle and was added HMG in 6th day and the 2nd group (n=70), received rFSH from the second day of cycle and was added recombinant-LH in 6th day. Then ovum Pick-Up and embryo transfer were performed. In this study, we assessed the outcomes such as; chemical and clinical pregnancy rate, live birth and abortion rate.
Results: Number of follicles in ovaries, total number of oocytes or M2 oocytes and quality of fetuses has no significant differences between two groups (p>0.05). Total number of fetuses were significantly higher in patients who received rFSH + HMG (p=0.02). Fertility outcomes consisted of: live birth rate, chemical pregnancy and clinical pregnancy rate were higher in rFSH + HMG group in comparison to rFSH +r-LH group (p<0.05).
Conclusion: It seems that in IVF patients, HMG + rFSH used for controlled ovarian hyperstimulation have better effects on fertility outcomes, but in order to verify the results, it is recommended to implement studies on more patients.

Abstract
Background: Ovarian stimulation (OS) for poor ovarian response (POR) patients is still a major challenge in assisted reproductive techniques. Aromatase inhibitors as co-treatment in antagonist protocol are suggested to these patients, but there are controversial reports.
Objective: To evaluate the effectiveness Letrozole (LZ) as adjuvant treatment in gonadotropin-releasing hormone (GnRH)-antagonist protocol in POR patients undergoing in vitro fertilization/ intracytoplasmic sperm injection cycles.
Materials and Methods: This double-blind randomized clinical trial was conducted in Arash womenchr('39')s hospital. One hundred sixty infertile women with POR based on Bologna criteria were allocated into two groups randomly: LZ + GnRH-antagonist (LA) and placebo + GnRH-antagonist (PA) groups. In the experimental group, the patients received 5 mg LZ on the first five days of OS with 150 IU of recombinant human follicle-stimulating hormone (rFSH) and 150 IU of human menopausal gonadotropin (HMG). The cycle outcomes were compared between groups.
Result: The total number of retrieved oocytes and the metaphase II oocytes in LA-treated group were significantly higher than those in the control group (p = 0.008, p = 0.002). The dosage of hMG used and the duration of OS and antagonist administration in LZ-treated group were significantly lower than those of the control group. The number of patients with no oocyte, in the control group, was higher than the LZ-treated group, and the clinical pregnancy rate in LA-treated group (25%) was higher than the control group (18%); however, the differences were not significant statistically.
Conclusion: Adding 5 mg of LZ to rFSH/hMG antagonist protocol may improve the in vitro fertilization/intracytoplasmic sperm injection cycle outcome in POR patients.

Abstract

Background: Pinopods concentrations in endometrial surface is a marker of implantation. estradiol valerate (EV) was used for change the adverse effects of Clomiphene Citrate (CC) on the endometrium. Endometrial morphology was less examined in this fields.
Objective (s): To assess whether there is a significant difference in endometrial pinopods concentrations and other parameters after adding estradiol valerate (EV) and progesterone to higher doses of clomiphene citrate (CC).
Study design: In this prospective randomized clinical trial, a total of 30 women, who did not respond to 100 mg CC from February 2016 until June 2016 were evaluated. They received 150 mg CC alone or CC with EV or CC plus progesterone. On day 21 of the menstrual cycle, endometrial biopsy and a blood sampling and scanning by electron microscopy were performed.

Results: On day 21 of the menstrual cycle there was no significant difference regarding pinopods concentrations (P=0.641) and serum estrogen levels (P=0.276) between groups. Serum progesterone levels on day 21 of the menstrual cycle among patients treated with CC, was higher than the other two groups (P=0.007).
Conclusions: The addition of EV and progesterone to higher dosages of CC, did not changes the pinopods concentration and serum estrogen levels on day 21 of the menstrual cycle. It can be concluded that the anti- estrogenic effects of CC just appear on the endometrium. In this study, there were higher levels of serum progesterone on day 21 of the menstrual cycles in the CC alone compared to other two groups.
