PURPOSE: Polar body biopsy (PBB) is a common technique in preimplantation genetic testing (PGT) to assess the chromosomal status of the oocyte. Numerous studies have been implemented to investigate the impact of biopsies on embryo development; however, information on embryo morphokinetics is still lacking. Hence, we investigated the impact of PBB on morphokinetic parameters in early embryo development. METHODS: Four hundred four embryos (202 PBB, 202 control) were retrospectively analyzed...

OBJECTIVES: Controlled ovarian hyperstimulation is an important step in infertility treatment. In some cases, however, ovar-ian hyperstimulation syndrome (OHSS) can occur. In its severe forms, ascites is likely to develop, associated with dyspnea. The aim of this study was to explore the usefulness of Ascites Index (AsI), a new tool for quantitative determination of ascites in patients with OHSS, to obtain data for planning further trials. MATERIAL AND METHODS: Twelve patients with OHSS and ascites were included in the study...

AR-mediated androgen signaling plays a key role in female reproductive system. Granulosa-lutein cells (GCs) are the main sites for expression of androgen receptor (AR). There is also a close relation between AKT signaling and AR. Here, we assayed the role for a synthetic AR ligand methyltrienolone (R1881) in expressions of AKTs and AR. Controlled ovarian hyperstimulation (COH) was performed in 20 normal women. Mural GCs were isolated by filtration method, cultured, and passaged. Then, the cells were starved for 48 h with 10% charcoal stripped FBS...

The presence of smooth endoplasmic reticulum aggregates (SERa) in the ooplasm is considered as the most severe oocyte dysmorphism due to its serious and potentially lethal outcomes in offspring. In the present case report, a couple underwent their first intracytoplasmic sperm injection (ICSI) cycle using a gonadotrophin releasing hormone (GnRH) antagonist protocol, followed by fetal ultrasound scanning and amniocentesis. SERa were observed in all oocytes retrieved. A singleton pregnancy was established. The second trimester fetal ultrasound scan revealed a female fetus with overlapping fingers in both hands, and amniocentesis was performed for the detection of chromosomal abnormalities...

PURPOSE OF REVIEW: Gonadotrophin in IVF increases the number of oocytes retrieved, and many doctors regard a high number of oocytes as a measurement of success in IVF. Thus, the dogma of more oocytes provides better IVF success has been broadly accepted. However, some European fertility specialists have argued against this concept, saying fewer eggs might, in some instances, be a better option for the patient. RECENT FINDINGS: The concept of 'one size fits all' stimulation in artificial reproductive technologies is not broadly supported by the current literature...

REVIEW
Sine Berntsen, Anja Pinborg
Increase in success rates with frozen embryo transfer (FET) and reduced risk of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancies has lead to a steady rise in FET. Further, FET is associated with lower risk of prematurity and low birth weight in singletons, when compared with fresh transfer. However, there is a growing concern of increased risk of large for gestational (LGA) and/or macrosomic children after FET. Macrosomic/LGA births have a higher risk of cesarean section, fetal hypoxia and stillbirth...

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of controlled ovarian stimulation. The use of gonadotropin releasing hormone (GnRH) agonist for the trigger of oocyte maturation is effective in the prevention of OHSS although it may result in a lower pregnancy rate. The use of adjuvant low dose human chorionic gonadotropin (hCG) at the time of trigger or at the time of oocyte retrieval may improve pregnancy rates. The goal of this dual trigger study is to evaluate the safety and efficacy of the use of low dose hCG administered at the time of GnRH agonist trigger or 35 h later as well as the potential impact on pregnancy rates...

Purpose: To evaluate the efficacy and safety of self-injections of the prefilled recombinant human chorionic gonadotropin (r-hCG) in a syringe in assisted reproductive technology (ART) treatment for the maturation trigger (MT), as compared to self-injections of conventional hCG and intranasal administration of gonadotropin-releasing hormone agonist (GnRH-a). Methods: Between January and April, 2017, 396 patients who underwent oocyte retrieval were recruited. Of these, 396 patients were classified into three groups, according to the types of MT: (1) the urinary human chorionic gonadotropin (u-hCG) group that consisted of patients who had a self-injection of u-hCG (n = 127); (2) the GnRH-a group that received nasal administration of GnRH-a (n = 159); and (3) the r-hCG group that had a self-injection of r-hCG (n = 110)...

Aim: Gonadotropin stimulation is used as the second line of treatment in patients with thin endometrium following clomiphene citrate (CC) administration, which is associated with higher cost, multiple births, and ovarian hyperstimulation syndrome. Tamoxifen (TMX), a selective estrogen receptor modulator, acts as an agonist on the endometrium. The objective of the present study was to compare the efficacy of low-dose CC, TMX, and gonadotropins in women with thin endometrium (<7 mm) following Clomiphene in intrauterine insemination (IUI) cycles...

Background: Assessment of ovarian reserve before an in vitro fertilization cycle (IVF) is one among the many factors that predicts a successful cycle. Individualized protocol based on ovarian reserve is designed to optimize the pregnancy outcome without compromising the patient safety. Although authors have shown that anti-Mullerian hormone-tailored (AMH) protocols have reduced the treatment burden and improved pregnancy rates, a few others have questioned its efficacy. Aims: The aim of this study was to decide whether the AMH-tailored protocol or the conventional protocol better decides IVF outcomes...

REVIEW
Claudio Benadiva, Lawrence Engmann
Despite the increasing utilization of freeze-only IVF protocols, there is still a need for adequate management of the luteal phase after GnRH agonist trigger for patients who desire a fresh embryo transfer. Two approaches, intensive luteal support with E2 and P, and the use of adjuvant low-dose hCG either at the time of GnRH agonist trigger (dual trigger) or at the time of oocyte retrieval, have been shown to be effective in maintaining adequate pregnancy outcomes. The addition of low-dose hCG should be used with caution, because it may increase the risk of ovarian hyperstimulation syndrome...

Background: The use of embryo cryopreservation excludes the possible detrimental effects of ovarian stimulation on the endometrium, and higher reproductive outcomes following this policy have been reported. Moreover, gonadotropin-releasing hormone agonist trigger in gonadotropin-releasing hormone (GnRH) antagonist cycles as a substitute for standard human chorionic gonadotropin trigger, minimizes the risk of ovarian hyperstimulation syndrome (OHSS) in fresh as well as frozen embryo transfer cycles (FET)...

OBJECTIVE: A high dose of prolonged gonadotropins can yield higher numbers of oocytes and embryos. The high dose or prolonged regimens can be associated with ovarian hyperstimulation syndrome (OHSS), multiple gestations, emotional stress, economical burden and treatment dropout. In mild stimulation lower doses and shorter duration times of gonadotropin are used in contrast to the conventional long stimulation protocol in IVF. It has been proposed that supraphysiologic levels of hormones may adversely affect endometrium and oocyte/embryo...

We aimed to investigate the different effects of low oxygen (5% O2 ) and atmospheric oxygen (20% O2 ) on in vitro fertilization for older poor ovarian responders (PORs). We selected 1080 older PORs who met two criteria: (i) advanced maternal age (≥40) and (ii) an abnormal ovarian reserve test. All the patients used the ultra-short term protocols with GnRH agonist and recombinant FSH for controlled ovarian hyperstimulation (COH). About 506 cycles were performed in the incubators with 5% O2 and 574 cycles were performed in the incubators with 20% O2 ...

PURPOSE OF REVIEW: Traditional approach of ovarian stimulation monitoring for in-vitro fertilization involves transvaginal sonography and serum estradiol measurements. Accumulating evidence has shown that hormonal evaluations during ovarian stimulation allow individual cycle optimization, moving away from only predicting the risk of ovarian hyperstimulation syndrome, but in addition assessing the impact of ovarian stimulation on endometrial receptivity, quality of oocytes, and subsequently embryos...

The study aimed to assess the effect of high estrogen exposure and coasting on cycle outcome in women at risk for developing ovarian hyperstimulation syndrome (OHSS). Retrospective case-control study was conducted to figure out the outcomes of GnRH antagonist cycles in which women were at risk to develop OHSS. Women who underwent coasting (n = 100) were compared with a control group of women who did not undergo coasting (n = 287). Effect of endometrial estrogen exposure was determined by calculating area under curve of temporal estrogen measurements (AUCEM) through the cycle...

Ventriculoperitoneal shunt (VPS) insertion is a common neurosurgical procedure for hydrocephalus. Unfortunately, VPS malfunction is not uncommon, with an estimated cumulative rate of 32% at 5 years. As flow through the shunt is influenced by the pressure gradient between the ventricles and the peritoneal cavity, malfunction may be caused by elevated intra-abdominal pressure. We present a rare patient with ascites following ovarian hyperstimulation syndrome (OHSS) leading to shunt malfunction. OHSS is a potentially life-threatening complication of controlled ovarian stimulation caused by the administration of exogenous gonadotropins...
