STUDY QUESTION: Can focused application of time-lapse microscopy (TLM) lead to a more detailed map of the morphokinetics of human fertilization, revealing novel or neglected aspects of this process? SUMMARY ANSWER: Intensive harnessing of TLM reveals novel or previously poorly characterised phenomena of fertilization, such as a cytoplasmic wave (CW) preceding pronuclear formation and kinetics of pronuclear chromatin polarization, thereby suggesting novel non-invasive biomarkers of embryo quality...

At present, there is no reliable in vitro assembled prepubertal testis-like biomimetic organ culture system designed to assess the functional effects of human gonadotropins on Sertoli and Leydig cells. Spermatogenesis is regulated by endocrine, paracrine, and juxtacrine factors (testicular cross-talk), mainly orchestrated by gonadotropins such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) that play a pivotal role by stimulating Leydig and Sertoli cells, respectively. The aim of our study was to set up an in vitro prepubertal porcine bioengineered construct as a new model for experimental studies on reassembled Sertoli and Leydig cells...

The DJ-1 gene is an oncogene and also causative gene for a familial form of Parkinson disease. Although exits of cancer and neurodegenerative diseases, including Parkinson disease, are completely opposite, there are some common points of view between both diseases, including growth and death signaling pathways, and oxidative stresses affect the onset and pathogenesis of both cancer and neurodegenerative diseases. DJ-1 has versatile functions and plays a role in protection against oxidative stress. Inactivation and/or excess activation of DJ-1 functions, therefore, leads to onsets of oxidative stress-related diseases such as type 2 diabetes and male infertility in addition to cancer and neurodegenerative diseases, and studies about DJ-1 will give rise to the common mechanism among these diseases...

Objectives: We intended to determine whether the ovarian varicose which is one of the common etiologies of the pelvic congestion syndrome, has the ability to interfere with the DNA methylation reprogramming in the oocyte and thereby affect the oocyte quality or not. Materials and Methods: Varicose model was induced according to the Turner's method in the rats. Briefly, a 20-gauge needle was placed on the left renal vein and a thread was tied over both the needle and the renal vein medial to the insertion of the ovarian vein, and then the needle was removed...

Proper physiological function of the ovaries is very important for the entire female reproductive system and overall health. Reactive oxygen species (ROS) are generated as by-products during ovarian physiological metabolism, and antioxidants are indicated as factors that can maintain the balance between ROS production and clearance. A disturbance in this balance can induce pathological consequences in oocyte maturation, ovulation, fertilization, implantation, and embryo development, which can ultimately influence pregnancy outcomes...

Infertility is a global health problem with an estimated incidence of 15%. Exposure to chemicals is a potential causal factor, and there is a lack of studies examining the effects on female germ cells. Here, we have studied the impact of different aryl hydrocarbon receptor (AHR) modulators on human ovarian follicles using a human ovarian tissue culture model. Expression of AHR was analyzed in tissue samples, and effects of the selected ligands resveratrol (RSVL), 6-formylindolo(3,2-b)carbazole (FICZ), and alpha-naphthoflavone (aNF) on AHR transactivation studied in a granulosa cell tumor line...

Infertile couples including cancer survivors stand to benefit from gametes differentiated from embryonic or induced pluripotent stem (ES/iPS) cells. It remains challenging to convert human ES/iPS cells into primordial germ-like cells (PGCLCs) en route to obtaining gametes. Considerable success was achieved in 2016 to obtain fertile offspring starting with mouse ES/iPS cells, however the specification of human ES/iPS cells into PGCLCs in vitro is still not achieved. Human ES cells will not yield patient-specific gametes unless and until hES cells are derived by somatic cell nuclear transfer (therapeutic cloning) whereas iPS cells retain the residual epigenetic memory of the somatic cells from which they are derived and also harbor genomic and mitochondrial DNA mutations...

BACKGROUND/AIMS: Obese and overweight women experience a lower probability for pregnancy after IVF. However, despite the increasing prevalence of obesity, the large majority of infertile women are non-obese. One of the most common indications for IVF is endometriosis. Thought-provoking inverse correlation has been established between BMI and endometriosis. Lower BMI is a risk factor for development of endometriosis and a predictive factor for severe endometriosis. Since severe endometriosis carries lower reproductive chances, even after IVF, we preliminary tested a hypothesis that higher BMI among non-obese endometriosis patients improves IVF outcomes...

PURPOSE: Some of the women that go through repeated fertility treatments will not adjust well to the treatments and will experience increased distress. The present study examined how centrality of the fertility problem in the woman's identity and dispositional goal adjustment (disengagement and reengagement) are associated with the woman's psychological adjustment. These issues are examined in a context of a pro-natal society (Israel) where parenthood is a major life goal. METHODS: One hundred ninety-three women in ongoing fertility treatments filled out questionnaires, and follow-up on their psychological well-being was carried out after 3 months (N = 130)...

BACKGROUND: Male factor infertility has increased to more than 40% during the last decade. About 30% of these couples are diagnosed with unexplained infertility. In fact, reactive oxygen species (ROS), especially superoxide anion (O2(-)·) and hydrogen peroxide (H2O2), play a crucial role in regulation of physiological and pathological processes in spermatozoa. Moreover, since the diagnosis of unexplained infertility just through semen analysis is a matter of much controversy; we aimed to evaluate the levels of ROS and sperm DNA fragmentation in the semen samples of unexplained infertile and fertile control couples...

Celiac disease (CD) is an immune-mediated enteropathy and is a rare disease in Asia, including in Korea. However, the ingestion of wheat products, which can act as a precipitating factor of CD, has increased rapidly. CD is a common cause of malabsorption, but many patients can present with various atypical manifestations as first presented symptoms, including anemia, osteopenia, infertility, and neurological symptoms. Thus, making a diagnosis is challenging. We report a case of CD that mimicked amyotrophic lateral sclerosis (ALS)...

Severe ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication of assisted reproductive technology. Herein, we report the case of an infertile couple, with the husband being azoospermic, who underwent in-vitro fertilisation and intracytoplasmic sperm injection at our institute. The woman presented with late OHSS 7 days after embryo transfer. Inpatient management was performed with intensive surveillance. Oral cabergoline was started prophylactically but was replaced by the vaginal route due to intolerance...

Mullerian anomalies cause a significant impact on the reproductive outcomes. A bicornuate uterus is a type of lateral fusion defect, which constitutes 26% of all uterine anomalies. Strassmann's metroplasty is a unification procedure performed to correct the two smaller uterine cavities into a more spacious single cavity. Improved reproductive performance was reported after unification metroplasty. Laparoscopic route can be adopted for this procedure with all the advantages of minimally invasive surgery. Here, we report a success story of a woman who suffered with six miscarriages and secondary infertility who underwent laparoscopic Strassmann's metroplasty in a tertiary care center and later delivered a baby by caesarean section...
