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.

This video demonstrates a technique for separating miscarriage tissue from maternal decidua to reduce maternal cell contamination for chromosome analysis.

Fertility after laparoscopic neosalpingostomy is largely dependent on the tubal status and should only be proposed for patients with tubal stage 1 or 2.

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.

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.

During pregnancy, regulation of the expression of human chorionic gonadotropin beta subunit genes correlates with methylation of their promoters and TFAP2A expression.

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.

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.

Patients with pelvic abscess treated with antibiotics alone are more likely to require surgical intervention than patients who also receive image guided drainage.

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.

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.

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.

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.

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.

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.

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.
