The germ cell transplant demonstrates that spermatogonial stem cells can engraft recipient seminiferous tubules and produce spermatogenesis. Here we describe the protocol for germ cell transplant by efferent duct injection.
All the papers from the October 2014 issue of Fertility and Sterility.
This video demonstrates a technique for separating miscarriage tissue from maternal decidua to reduce maternal cell contamination for chromosome analysis.
Laparoscopic surgery for distal tubal occlusions Lessons learned from a historical series of 434 cases
Fertility after laparoscopic neosalpingostomy is largely dependent on the tubal status and should only be proposed for patients with tubal stage 1 or 2.
Randomized experimental study to investigate the peritoneal adhesion formation of conventional monopolar contact coagulation versus noncontact argon plasma coagulation in a rat model
Conventional monopolar contact coagulation induces significantly more adhesions that are more vascularized than noncontact argon plasma in a randomized experimental rodent model.
RvD1 and 17(R)-RvD1 reduced cyst vascular permeability and associated vaginal hyperalgesia in rats with surgically-induced endometriosis suggesting that further investigation of therapeutic anti-inflammatory potentials of resolvins can be considered.
Effect of oocytes vitrification on deoxyribonucleic acid methylation of H19 Peg3 and Snrpn differentially methylated regions in mouse blastocysts
Vitrification can lead to a loss of deoxyribonucleic acid methylation of imprinted genes in blastocysts, possibly because of reduction of deoxyribonucleic acid methyltransferase abundance in mouse MII oocytes after vitrification.
Methylation status of human chorionic gonadotropin beta subunit promoter and TFAP2A expression as factors regulating CGB gene expression in placenta
During pregnancy, regulation of the expression of human chorionic gonadotropin beta subunit genes correlates with methylation of their promoters and TFAP2A expression.
Association of abdominal obesity insulin resistance and oxidative stress in adipose tissue in women with polycystic ovary syndrome
The strong correlation of insulin resistance and oxidative stress at the visceral adipose tissue level suggests that local oxidative stress and abnormalities of insulin signaling in the adipose tissue play critical roles in polycystic ovary syndrome insulin resistance.
Preferences and needs regarding future contact with donation offspring among identity release gamete donors Results from the Swedish Study on Gamete Donation
Several years after donation, a majority of 210 identity-release donors feel positive about future contact with an offspring, and their preferences should be taken into account by health-care services.
Image guided drainage versus antibiotic only treatment of pelvic abscesses Short term and long term outcomes
Patients with pelvic abscess treated with antibiotics alone are more likely to require surgical intervention than patients who also receive image guided drainage.
Genetic variation of the E cadherin gene is associated with primary infertility in patients with ovarian endometriosis
The study showed that genetic variants on the E-cadherin gene may be a potential molecular marker for the development of primary infertility in northern Chinese women with ovarian endometriosis.
Gene dose effect between a fat mass and obesity associated polymorphism and body mass index was observed in Korean women with polycystic ovary syndrome but not in control women
In women with polycystic ovary syndrome, the variant allele of Fat mass and obesity associated (FTO) rs9939609 was associated with increased body mass index.
MED12 mutations inversely correlate with leiomyoma size; in this study where size bias is carefully controlled, over 80% of uterine leiomyomas display a MED12 mutation.
Genome wide copy number analysis and systematic mutation screening in 58 patients with hypogonadotropic hypogonadism
Molecular analyses of 58 patients with hypogonadotropic hypogonadism revealed the relatively minor contribution of known genetic defects, and identified submicroscopic genomic rearrangement and SOX3 and WDR11 mutations as rare etiologies.
This is the first study showing that repeated ejaculates from cancer patients did not show substantial variation in semen quality.
Is subfertility or fertility treatment associated with long term growth in the offspring A cohort study
Compared with children born to fertile parents, no systematic differences were observed for body weight, height, body mass index, or head circumference at age 5 in children conceived after fertility treatment or in children born to subfertile parents.
Perinatal outcomes in 6338 singletons born after intrauterine insemination in Denmark 2007 to 2012 The influence of ovarian stimulation
Treatment with clomiphene citrate is associated with an increased risk of small for gestational age in children born after intrauterine insemination, whereas ovarian stimulation with follicle-stimulating hormone did not seem to increase the risk of adverse perinatal outcomes.
The study results suggest that physical activity is not deleterious to testicular function, as captured by semen quality parameters in this population of healthy young men in Spain.
Incidence of hypertension stroke coronary heart disease, and diabetes in women who have delivered after in vitro fertilization A population based cohort study from Sweden
In a cohort study, the incidence of hypertension increased in women after IVF pregnancies, suggesting that these women could have a propensity to develop cardiovascular disease later in life.
Prokineticin 1 and leukemia inhibitory factor mRNA expression in the endometrium of women with idiopathic recurrent pregnancy loss
Increased mRNA expression of prokineticin 1 and leukemia inhibitory factor could be one of several abnormalities characterizing the endometrium of women with recurrent pregnancy loss.
