Stress increases the risk of pregnancy failure in couples undergoing IVF.

This study was designed to examine the relationship between the stress level as inferred from the amount of the enzyme alpha-amylase secreted in saliva (SAA) and pregnancy outcome in infertile couples undergoing in vitro fertilization and embryo transplantation (IVF-ET). A prospective cohort study was conducted in the Reproductive Medicine Centre of Zhengzhou University Hospital in Henan, China. Four hundred fifty-seven infertile couples undergoing in vitro fertilization and embryo transplantation (IVF-ET) for the first time participated in the study. Couples collected saliva samples the morning before the start of their first treatment cycle for the measurement of SAA. We found that the level of SAA (and hence, the amount of stress) in female partners, male partners, and couples analyzed together significantly affected IVF-ET outcome. Cutoff levels of SAA that predicted pregnancy failure were 136 μmol/L, 149 μmol/L, and 288 μmol/L in female partners, male partners, and couples, respectively. Female partners, male partners, and couples with high SAA levels had increased risk of pregnancy failure compared to those with low SAA levels. The SAA level directly correlated with the follicle-stimulating hormone level and was inversely proportional to the anti-Müllerian hormone level and endometrial thickness. Some semen parameters of male partners, such as density, survival rate, sperm rapid progressive motility (A%), and progressive motility [(A&t...

Being born and giving birth is full of pain, blood, and trauma. Many science fiction works, such as Brave New World, Matrix, The Island, or I am Mother imagine being brought to the world without actually being born in a mother’s womb. How far-fetched are these scenarios? Could the appearance of the artificial womb replace human mothers and natural birth in the future? How will we come into this world in 2050? Will we be born? The trauma of being born and giving birth The experience of being born and leaving the nurturing womb of our mother after more or less nine months is painful, bloody, and traumatic. Abrupt...

This study aimed to investigate the effect of different gonadotropin-releasing hormone agonist (GnRH-a) administration methods on pregnancy outcomes of patients undergoingin-vitro fertilization-embryo transfer (IVF-ET). Clinical data of 5217 patients who underwent IVF-ET were retrospectively analyzed. Patients were divided into the long-acting GnRH-a group (n=1330) and the short-acting GnRH-a group (n=3887) based on their various treatment plans. The clinical and laboratory embryo data and clinical pregnancy outcomes were compared between the two groups. The results showed that there were no significant differences in the ...

Conclusions In both mouse and human, uNK cells are the most prominent immune cells that occupy the maternal-fetal interface. The uNK cells appear to engage and establish complex interactions with the surrounding tissue, which impact their function. As more cell subsets are identified within the heterogeneous uNK cell population, it is anticipated that their functional heterogeneity will extend beyond vascular modification, growth-promotion and memory generation. Author Contributions DS wrote the manuscript. LY provided the micrographs and WY edited the manuscript. Funding Work in the Yokoyama lab on uterine NK cells i...

Uterine factor infertility (UFI) may affect up to 1 in 500 reproductive age women. The uterus is an essential component of achieving pregnancy and carrying a pregnancy to term successfully. There are many etiologies of UFI which may be categorized into either congenital or acquired causes. In this review, we discuss the different causes of UFI as well as the treatment options, which now includes uterine transplant.

cute; Abstract Systemic lupus erythematosus is the most characteristic of auto-immune disorders that can lead to tissue damage in many organs, including kidney. Lupus nephritis occurs in 10 to 40% of lupus patients. Its clinical hallmark is the appearance of a proteinuria as soon as a 0.5 g/g or 0.5 g/d threshold, which calls for a renal histological evaluation in order to determine the lupus nephritis severity and the need for specific therapy. More than half of renal biopsies lead to the diagnosis of active lupus nephritis-class III or class IV A according to the ISN/RPS classification-t...

On an afternoon in November, a couple hosted a birthday party for their 1-year-old son. As family and friends gathered around the child to sing “Happy Birthday,” his parents addressed a milestone that reached well beyond the room. “It was emotional,” recalls the mother. “It took a lot more than a nine-month pregnancy to get him, and we wouldn’t be where we are without everyone’s support.” Many parents will tell you their child is miraculous. But the mere existence of this particular boy, who just a month earlier had taken his first steps, brings the miracle somehow closer to ...

When Noah Shulman was born a few days after Christmas 2016, his parents Kristelle and Evan had no reason to worry about him. The pregnancy went smoothly, and so did the birth. But within a few days of taking his first breath, Noah began to struggle. He wasn’t feeding, so he started losing weight. He was also lethargic. Several pediatricians reassured the Shulmans that they were probably just overly sensitive to Noah’s symptoms because Kristelle is a nurse and Evan is a physician assistant–a case of first-time-parent-white-coat syndrome. “They kind of dismissed us as neurotic parents,” says Eva...

Concerning gynaecological cancer, AUFI may occur after hysterectomy for malignancy or after surgery/radiation that ...
