OBJECTIVE: Epilepsy is the most common neurological chronic condition worldwide, affecting about 2% of world population. Temporal lobe epilepsy (TLE) reaches 40% of all cases of this condition, and it is highly refractory to pharmacological treatment. Physical activity has been suggested as complementary therapy for epilepsy. However, there is no consistent information whether all these effects are plenty applicable to females, since clinical and experimental studies concerning physical exercise and epilepsy are largely performed in males...

This global overweight and obesity epidemics has become one of the largest public health problem worldwide and is increasingly more common among women in reproductive age. Along with the prevalence of overweight women, there is an increase in women with anovulatory infertility. Thus, we carried out a bibliographic research in the PubMed, Lilacs and SciELO databases, using the combinations in Portuguese, Spanish and English of the following descriptors: "Body Mass Index", "obesity", "overweight", "female infertility" and "anovulation"...

BACKGROUND: Infertility has been described as a devastating life crisis for couples, and has a particularly severe effect on women, in terms of anxiety and depression. Anovulation accounts for around 30% of female infertility, and while lifestyle factors such as physical activity are known to be important, the relationship between exercise and ovulation is multi-factorial and complex, and to date there are no clear recommendations concerning exercise regimes. OBJECTIVES: The objective of this review was to systematically assess the effect of physical activity on ovulation and to discuss the possible mechanisms by which exercise acts to modulate ovulation in reproductive-age women...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and affects fertility and pregnancy in cases of oligoanovulation. Ovulation induction is often used to treat anovulatory patients with PCOS, but many of these women fail to conceive and resort to assisted reproductive technologies. Alterations in oocyte competence (OC) are considered potential causative factors for subfertility in women with PCOS. In this review we present and critically assess all recent clinical and experimental data regarding OC in women with PCOS...

BACKGROUND: Subfertility due to anovulation is a common problem in women. First-line oral treatment is with antioestrogens such as clomiphene citrate, but resistance may be apparent with clomiphene. Alternative and adjunctive treatments have been used including tamoxifen, dexamethasone, and bromocriptine. The effectiveness of these is to be determined. OBJECTIVES: To determine the relative effectiveness of antioestrogen agents including clomiphene alone or in combination with other medical therapies in women with subfertility associated with anovulation, possibly caused by polycystic ovarian syndrome...

OBJECTIVE: The aim of this study was to evaluate an individualised gonadotrophin starting dose regimen for women with anovulatory infertility. STUDY DESIGN: We included 71 normogonadotrophic anovulatory infertile women in a prospective, observational study. All underwent one ovulation induction cycle in a flexible, low-dose step-up protocol. The gonadotrophin starting dose (75-150IU/day) was individualised according to a nomogram incorporating menstrual cycle pattern (oligo- or amenorrhoea), BMI, and mean ovarian volume...

INTRODUCTION: Polycystic ovary syndrome is the most frequent cause of anovulatory infertility and management involves a multistep approach. Laparoscopic ovarian diathermy is accepted as a second-line treatment of patients who failed to respond to clomiphene citrate. The aims of this study were to determine the efficacy of this technique at short and long-term and to perform an analysis of predictive factors of spontaneous pregnancy. MATERIAL AND METHODS: This retrospective study involved 76 women who underwent laparoscopic ovarian diathermy between 2004 and 2013 in a university hospital...

INTRODUCTION: The high prevalence of insulin resistance in women with polycystic ovary syndrome (PCOS) is considered to be one of the major pathophysiological changes in PCOS that leads to anovulatory infertility. We hypothesise that electroacupuncture pretreatment improves insulin sensitivity and leads to a higher ovulation rate and greater chances of live birth after the induction of ovulation. The effect of electroacupuncture pretreatment followed by ovulation induction in women with anovulatory PCOS has not been investigated before, and we present here a randomised controlled trial to test this hypothesis by comparing electroacupuncture pretreatment followed by letrozole versus letrozole alone in anovulatory women with PCOS...

Autophagy, a process of controlled cellular self-digestion, could be involved in cyclic remodeling of the human endometrium. We investigated endometrial mRNA expression of 23 autophagy-related (ATG) genes and transcription factors in healthy controls (n = 12) and anovulatory polycystic ovary syndrome (PCOS) patients (n = 24), as well as in their subgroup (n = 12) before and after metformin treatment. The mRNA levels of transcription factor forkhead box protein O1 (FOXO1) and several molecules involved in autophagosome formation (ATG13, RB1-inducible coiled-coil 1), autophagosome nucleation (ATG14, beclin 1, SH3-domain GRB2-like endophilin B1), autophagosome elongation (ATG3, ATG5, γ-aminobutyric acid receptor-associated protein - GABARAP), and delivery of ubiquitinated proteins to autophagosomes (sequestosome 1), were significantly reduced in anovulatory PCOS compared to healthy endometrium...

Polycystic ovary syndrome (PCOS) is a common endocrine disorder, with complex etiology and pathophysiology, which remains poorly understood. It affects about 5-10% of women of reproductive age who typically suffer from obesity, hyperandrogenism, ovarian dysfunction, and menstrual irregularity. Indeed, PCOS is the most common cause of anovulatory infertility in industrialized nations, and it is associated with insulin resistance, type 2 diabetes mellitus, and increased cardiovascular risk. Although insulin resistance is not included as a criterion for diagnosis, it is a critical pathological condition of PCOS...

The effect of goat nutritional condition on the response to biostimulation with sexually active males during different stages of anestrus was determined. Fifty-eight Criollo × Nubian females on high and low body mass index (BMI) diets were used. Each BMI group was divided into two for biostimulation with sexually active males during May (mid-anestrus) or July (transition period). Ovulatory responses to biostimulation were characterized from serum progesterone, as well as the delay for response (first and second ovulations followed by a normal length luteal phase, O-WNLP)...

BACKGROUND: Cervical incompetence is an important cause of miscarriage and premature birth and polycystic ovary syndrome is a heterogeneous endocrine disorder that is the most common cause of anovulatory infertility and eugonadotrophic hypogonadism. By now, it is still debated whether women with PCOS have an increased risk of miscarriage and there have been no studies about the pregnancy outcomes of cervical incompetence patients with PCOS. METHODS: The following clinical data of cervical incompetence patients with/without PCOS who were treated between September 2006 and September 2013 were retrospectively analysed: onset gestational age, termination gestational age, pregnancy outcome, co-morbid insulin resistance (IR) in PCOS patients, the influence of IR, co-morbid hyperandrogenism (HA) in PCOS patients, and the influence of HA...

Hypersecretion of luteinizing hormone (LH) is a common endocrinological finding of polycystic ovary syndrome (PCOS). This derangement might have a close relationship with hypothalamic kisspeptin expression that is thought to be a key regulator of gonadotropin-releasing hormone (GnRH). We evaluated the relationship between the hypothalamic-pituitary-gonadal axis (HPG axis) and kisspeptin using a rat model of PCOS induced by letrozole. Letrozole pellets (0.4 mg/day) and control pellets were placed subcutaneously onto the backs of 3-week-old female Wistar rats...

We determine whether Dorper rams treated with testosterone in the sexual resting season trigger both appetitive and consummatory sexual behaviors and sexual and reproductive outcomes in anestrous ewes at 26° North during March-April. Dorper rams (n = 12, 2.5 years) were randomly divided prior to mating in two groups: GT (treated group; n = 6), treated with testosterone propionate (25 mg i.m. every 3 days × 3 weeks) and GC (control group; n = 6), treated with saline. Thereafter, adult anovulatory Dorper ewes (n = 61) were exposed to the GT-rams while the other group (n = 60) was exposed to the GC-rams...
