OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic condition, predominantly related to the hormone used to induce oocyte maturation during IVF treatment. Kisspeptin is a hypothalamic neuropeptide that has recently been demonstrated to safely trigger final oocyte maturation during IVF treatment even in women at high risk of OHSS. However to date, the safety of kisspeptin has not been compared to current hormonal triggers of oocyte maturation. DESIGN: We conducted a retrospective single-centre cohort study investigating symptoms and clinical parameters of early OHSS in women at high risk of OHSS (antral follicle count or total number of follicles on day of trigger ≥23) triggered with hCG (n=40), GnRH agonist (GnRHa; n=99), or kisspeptin (n=122) at Hammersmith Hospital IVF unit, London, UK (2013-2016)...

BACKGROUND: The usage of Artificial Neural Networks (ANNs) for genome-enabled classifications and establishing genome-phenotype correlations have been investigated more extensively over the past few years. The reason for this is that ANNs are good approximates of complex functions, so classification can be performed without the need for explicitly defined input-output model. This engineering tool can be applied for optimization of existing methods for disease/syndrome classification. Cytogenetic and molecular analyses are the most frequent tests used in prenatal diagnostic for the early detection of Turner, Klinefelter, Patau, Edwards and Down syndrome...

C1q/tumor necrosis factor-related protein 3 (C1QTNF3) is a novel adipokine with modulating effects on metabolism, inflammation, and the cardiovascular system. C1QTNF3 expression levels in the sera and omental adipose tissues of women with PCOS are low compared to control subjects. However, the expression and function of C1QTNF3 in the ovary has not previously been examined. Here, we assessed the expression patterns of C1qtnf3 in the ovary and explored its role in folliculogenesis. The C1qtnf3 transcript abundance was higher in large follicles than in small follicles and was under the influence of gonadotropin...

AIM: Hypogonadotropic hypogonadism (HH) is a condition caused by the deficient secretion of pituitary gonadotropins, leading to diminished ovarian function. Several studies of in vitro fertilization (IVF) in women with HH revealed acceptable clinical pregnancy outcomes but high multiple pregnancy rates after multiple fresh embryo transfer (ET). The purpose of this study was to analyze the outcomes of combined freeze-all embryos and single vitrified-warmed ET in women with HH. METHODS: Of 91 infertile women with HH (basal luteinizing hormone and follicle-stimulating hormone levels <2...

STUDY QUESTION: Is the negative correlation between the numbers of 2-5 and 6-9 mm follicles influenced by ovarian and/or metabolic parameter(s) in young control women and in patients with polycystic ovarian syndrome (PCOS)? SUMMARY ANSWER: Our study confirmed that the negative correlation between numbers of follicles sized 2-5 and 6-9 mm was stronger in PCOS than in young control women and was not linked to any ovarian or metabolic parameter. WHAT IS KNOWN ALREADY: Previous reports described a direct negative correlation between the number of small antral follicles (2-5 mm) and large antral follicle (6-9 mm) during the early follicular phase (cycle Days 2-5) in normal and PCOS women...

This study aimed to determine whether consecutive ovarian stimulation in follicular and luteal phases within a single menstrual cycle (dual stimulation) is achievable and superior to conventional stimulation for poor ovarian responders (PORs). Data of 260 PORs were retrospectively collected and divided into three groups. Group A comprised of cycles with dual ovarian stimulation (n = 76), which were divided into two subgroups (follicular [group A-F] and luteal phase stimulation [group A-L]); group B comprised of cycles with ovarian stimulation that was performed only in the luteal phase (n = 52)...

BACKGROUND: During a cycle of in vitro fertilisation plus intracytoplasmic sperm injection (IVF/ICSI), women receive daily doses of gonadotropin follicle-stimulating hormone (FSH) to induce multifollicular development in the ovaries. Generally, the dose of FSH is associated with the number of eggs retrieved. A normal response to stimulation is often considered desirable, for example the retrieval of 5 to 15 oocytes. Both poor and hyper-response are associated with increased chance of cycle cancellation...

With advances in the methods of cancer treatment used in modern medicine, the number of breast cancer survivors has been consistently rising. As the number of women who wish to become pregnant after being diagnosed with breast cancer increases, it is necessary to consider fertility preservation in these patients. However, medical doctors may be unaware of the importance of fertility preservation among cancer patients because most patients do not share their concerns about fertility with their doctors. Considering the time spent choosing and undergoing treatment, an early referral to a reproductive specialist is the best way to prevent a delay in cancer treatment...

GnRH neurons regulate reproduction through pulsatile GnRH release. Women with polycystic ovary syndrome (PCOS) have persistently elevated LH release frequency reflecting GnRH release; this exacerbates hyperandrogenemia and disrupted reproductive cycles characteristic of this disorder. Clinical evidence suggests neuroendocrine features of PCOS may manifest peripubertally. Adult mice prenatally exposed to androgens (PNA) mimic several reproductive features of PCOS. GnRH neurons from these mice have increased firing activity and receive increased GABAergic transmission, which is excitatory...
