COVID-19 does not seem to have any short-term effects on male fertility in patients with mild symptoms. SARS-CoV-2 was not detected in semen of recovered and COVID-19 acute infected men.
SARS-CoV-2 infection risk assessment in the endometrium: viral infection-related gene expression across the menstrual cycle
Expression of SARS-CoV-2 infection-related genes in the endometrium show different risks of infection de- pending on menstrual cycle phases, women’s age, and viral cell entry mechanisms.
First effective mHealth nutrition and lifestyle coaching program for subfertile couples undergoing in vitro fertilization treatment: a single-blinded multicenter randomized controlled trial
Endometrial thickness is associated with incidence of small-for-gestational-age infants in fresh in vitro fertilization–intracytoplasmic sperm injection and embryo transfer cycles
After fresh in vitro fertilization with embryo transfer, the risk of small for gestational age infants was increased twofold in women with endometrial thickness ≤7.5 mm compared with >12 mm.
Mortality from infancy to adolescence in singleton children conceived from assisted reproductive techniques versus naturally conceived singletons in Sweden
Conception through in vitro fertilization–intracytoplasmic sperm injection, especially using cryopreserved embryos, was associated with higher infant mortality in singleton children, predominantly during the first week of life.
Oocytes of women who are obese or overweight have lower levels of n-3 polyunsaturated fatty acids compared with oocytes of women with normal weight
There are remarkable differences in the oocyte fatty acid profile by body weight. Women who are obese or overweight have lower amounts of n-3 fatty acid.
Effect of a 6-week “Mediterranean” dietary intervention on in vitro human embryo development: the Preconception Dietary Supplements in Assisted Reproduction double-blinded randomized controlled trial
Couples randomized to a nutrient-rich diet had higher blood levels of eicosapentaenoic acid, docosahexaenoic acid, and vitamin D, and their embryos showed altered morphokinetic markers of development.
Therapeutic endometrial scratching and implantation after in vitro fertilization: a multicenter randomized controlled trial
Endometrial scratching in the luteal phase preceding ovarian stimulation significantly enhances the clinical pregnancy rate in women with three or more prior implantation failures.
ASTEROID 1 (phase 2b) supports the efficacy and safety of vilaprisan for treatment of uterine fibroids, and 2.0 mg vilaprisan is the selected dose.
Reproductive performance after the application of hyaluronic acid gel after dilation and curettage in women who have experienced at least one previous curettage: long-term results of a multicenter prospective randomized trial
Intrauterine application of auto-cross-linked hyaluronic acid after dilatation and curettage for miscarriage in women who have experienced at least one previous D&C may have a favorable effect on reproductive performance.
Medical comorbidities are associated with impaired sperm production, and the treatment of comorbidities is beneficial for not only for general health status but also for spermatogenesis restoration.
Parental subfertility and hypospadias and cryptorchidism in boys: results from two Danish birth cohorts
Compared to those conceived spontaneously, boys conceived after fertility treatment had higher occurrence of hypospadias, but not cryptorchidism. Waiting time-to-pregnancy was not associated with hypospadias or cryptorchidism.
In this 25-year follow-up study of 1,544 girls, we found that childhood obesity before 12 years of age appears to increase the risk of female infertility in later life.
Maternal diabetes mellitus and timing of pubertal development in daughters and sons: a nationwide cohort study
Gestational diabetes may accelerate pubertal development in daughters. The potential effects of pregestational diabetes on daughters’ puberty and any type of diabetes on sons’ puberty remain uncertain.
