Diminished Ovarian Reserve Predisposes to Premature Luteinizing Hormone Surges in Gonadotropin-Releasing Hormone Antagonist Cycles in In vitro Fertilization.

CONTEXT/BACKGROUND: A premature luteinizing hormone (LH) surge, in in vitro fertilization (IVF) cycles with gonadotropin-releasing hormone (GnRH)-antagonist downregulation, leads to cycle cancellation. Currently, risk factors for the development of premature LH surge remain unknown. OBJECTIVE: The aim of the study was to determine the incidence and identify the contributing factors for premature LH surge in IVF cycles with GnRH antagonist suppression. DESIGN: This was a retrospective cohort study. SETTING: IVF-embryo transfer program at a fertility and research center. MATERIALS AND METHODS: The study included all patients undergoing IVF from December 1, 2014, to November 30, 2018, in whom GnRH-antagonist (cetrorelix 0.25 mg/d) flexible protocol was used. The primary outcome measure was the identification of premature LH surges (documented by a 2.5-fold increase in LH from the baseline above a threshold of 17 mIU/mL) with or without a decrease in E2 and appearance of free fluid on ultrasound. RESULTS: Premature LH surges occurred in 15 (2.16%) of 692 patients undergoing IVF with GnRH-antagonist suppression. Patients with premature surges had significantly lower ovarian reserve as compared to the controls (as seen from their higher age group, higher day 2 follicle-stimulating hormone (FSH), lower antral follicle counts, and lower anti-Müllerian hormone). CONCLUSIONS: Premature LH surge in a GnRH-antagonist cycle can lead to cycle cancellation and disappointment. Although this is a rare event, the incidence is higher in patients with diminished ovarian reserve. Further studies are needed to determine if giving the human chorionic gonadotropin trigger a day earlier or giving higher doses of GnRH-antagonist can benefit such cases.

Intracytoplasmic Sperm Injection with Assisted Oocyte Activation Resulting in Successful Pregnancies and Live Birth in Couples with Globozoospermia: A Report of Two Cases.

Globozoospermia, characterized by round-headed acrosomeless sperm, is a rare and severe form of teratozoospermia. We report a successful pregnancy in two cases of total globozoospermia after intracytoplasmic sperm injection (ICSI) with oocyte activation with calcium ionophore. In thefirst case, globozoospermia was diagnosed on the day of oocyte retrieval. Among 11 retrieved oocytes, only one fertilized after ICSI. The pregnancy test 2 weeks after embryo transfer was negative. Two months later, the patient underwent ovarian stimulation again. The 12 retrieved oocytes were exposed to calcium ionophore medium following ICSI. Four oocytes were fertilized and two blastocysts were transferred resulting in a clinical pregnancy. In the second case, among seven retrieved oocytes, three fertilized after ICSI and assisted oocyte activation, and two 8-cell embryos were transferred, resulting in a positive pregnancy. The successful outcome here justifies the use of ICSI with oocyte activation to improve the pregnancy rate significantly when dealing with globozoospermia.

Conservative management of cesarean scar pregnancy with uterine arteriovenous malformation: a case report.

BACKGROUND: Cesarean scar pregnancy is a rare type of ectopic pregnancy in which implantation occurs in a previous lower segment cesarean scar. It may be associated with uncontrolled hemorrhage ending in hysterectomy. It can become potentially life threatening for the patient when it further gets complicated by uterine arteriovenous malformation (AVM). To the best of our knowledge there are only a few previous reports of AVM complicating a scar pregnancy. It is still unclear which treatment is most optimal. CASE: We describe a case of a scar pregnancy complicated by uterine AVM. The diagnosis was made using 3D color Doppler ultrasound, showing a highly vascular tumor in the isthmic region of the uterus. Computed tomography angiography supported the diagnosis. The patient underwent selective embolization of the uterine artery followed by weekly intramuscular injections of methotrexate. Recovery was uneventful. CONCLUSION: The decision regarding mode of treatment should be made by the patient and the clinician based on the local expertise and experience. Judicious use of medical management (methotrexate) and uterine artery embolization may prevent hysterectomy and allow preservation of fertility.

Intravenous iron sucrose versus oral iron in treatment of iron deficiency anemia in pregnancy: a randomized clinical trial.

AIM: Iron deficiency is a leading cause of anemia in pregnancy. The present study aimed to compare the efficacy of oral and intravenous iron therapy in improving iron deficiency anemia in pregnancy and restoring iron stores, compare the obstetric outcome in the two groups and evaluate the safety of intravenous iron sucrose. MATERIAL AND METHODS: This was a prospective study, where 100 anemic antenatal women with hemoglobin 7-9 g/dL, mean corpuscular volume <85 fL and serum ferritin <15 ng/mL, were randomized into two groups. In group A (n=50), the women received 200 mg tablets of ferrous sulphate, each containing 60 mg elemental iron, three times a day for 4 weeks. In group B (n=50), iron sucrose was given in divided doses of 200 mg each on alternate days by slow intravenous infusion. Primary outcome measure was treatment efficacy, assessed by measurement of hemoglobin, red blood cell indices and reticulocytes on days 7, 14, 21, and 30 and at delivery, and of ferritin on day 30 and at delivery. Any side-effects of treatment and the neonatal outcome were studied as secondary outcome measures. RESULTS: There was a statistically significant difference in increase of hemoglobin levels (3.1g/dL in group A vs 5.1 g/dL in group B; P=0.002) and ferritin levels between the two groups on day 30 (P=0.005). The adverse effects from iron treatment were mild but more prominent in group A. Neonatal outcome was comparable in the two groups. CONCLUSION: Intravenous administration of iron sucrose is a safe treatment for correction of anemia in pregnancy, without serious side-effects.

Reproductive outcome of couples with recurrent miscarriage and balanced chromosomal abnormalities.

AIM: Despite known association of parental carriers of structural chromosomal rearrangements with a history of recurrent pregnancy loss (RPL), the possibility of having a miscarriage due to an unbalanced chromosomal aberration remains unknown. There has been limited research on the reproductive outcome of such couples. The present study was done to report the distribution of structural chromosome rearrangements in patients experiencing RPL and to describe subsequent pregnancy outcomes in the carriers. MATERIAL AND METHODS: Chromosomal analysis was performed on blood samples from 788 individuals with RPL and distribution of chromosomal anomalies was studied. In couples found to have chromosomal rearrangements, pregnancy outcomes were recorded over 2 years. In the subsequent pregnancy, cytogenetic analysis was done on amniotic fluid (obtained at 16-20 weeks), or on miscarriage specimens (in pregnancies that failed to continue). RESULTS: Chromosomal rearrangements were identified in 6.8% (54/788) cases (including 5.9% reciprocal translocations, 0.7% Robertsonian translocations, and 0.1% inversions). The risk of having a chromosomal aberration was not related to the number of previous miscarriages. Over the next 2 years, two-thirds of the 49 documented pregnancies resulted in a normal live birth, and one-third miscarried. Most miscarriages (56.2%) were euploid, two were trisomic and 12.5% had an unbalanced translocation. CONCLUSION: In couples with no other cause of RPL other than a structural chromosomal rearrangement, nearly two-thirds are likely to have a normal outcome in subsequent pregnancy. Couples with pure abortion histories carry higher risk for cytogenetic abnormality than couples with normal children in addition to abortions.

Obstetric and gynecological outcome in a patient with traumatic pelvic fracture and perineal injuries.

A 19-year-old woman presented with pelvic trauma following a road accident. She was hemodynamically stable. Examination revealed perineal injuries and type C pelvic fracture, which was stabilized with an external fixator. The broken ends of the pubic bone were brought together by an orthopedic wire. The detached vaginal wall and torn anal sphincter were surgically repaired after making a diverting colostomy. The postoperative period was uneventful. Colostomy was reversed after 3 months. Postoperatively the patient developed a cystocele, dyspareunia and vaginal pain. She conceived spontaneously and was planned for an elective cesarean at 37 weeks gestation; however, she presented in labor at 36 weeks and had a normal vaginal delivery. Pelvic fractures may be associated with genitourinary and anal sphincter injuries, which require management by a multidisciplinary team. On recovery the patient may develop prolapse, dyspareunia and persistent local pain. Spontaneous conception and normal vaginal delivery are nevertheless possible.
