Expert Rev Mol Diagn. 2021 Sep 23. doi: 10.1080/14737159.2021.1985469. Online ahead of print.ABSTRACTINTRODUCTION: Infertility is a major health problem, worldwide, which affects 10-15% of couples. About half percent of infertility cases are related to male-related factors. Male infertility is a complex disease that is the result of various insults as lifestyle issues, genetics, and epigenetic factors. Idiopathic infertility is responsible for 30% of total cases. The genetic factors responsible for male infertility include chromosomal abnormalities, deletions of chromosome Y, and mutations and genetic variations of key gen...

Conclusions Tubal factor infertility prevalence was 2-fold higher among Black than White women seeking care for infertility. Among women with TFI, data suggested a lower likelihood of Black women starting IVF than White women. Improved sexually transmitted disease prevention and treatment might ameliorate disparities in TFI.

In conclusion, the endometrial blood flow after LM changed over time, and recovery of blood flow was negatively correlated with patient age.IMPACT STATEMENTWhat is already known on this subject? Uterine blood flow is important for wound healing after myomectomy, but no studies have evaluated endometrial blood flow after myomectomy.What do the results of this study add? The endometrial blood flow impedance of RA-RI increased after LM and returned to before surgery at 3 months postoperatively. RA-RI recovery index negatively correlated with patient age.What are the implications of these findings for clinical practice and/or ...

Biol Reprod. 2021 Sep 23:ioab179. doi: 10.1093/biolre/ioab179. Online ahead of print.ABSTRACTCurrently, spermiogram analysis is the most relevant method used to clarify the potential infertility of a couple. However, in some cases, the reasons for infertility remain obscure. Smoking is among the factors that have been described to adversely affect male fertility. Smoking increases oxidative stress and thus promotes various pathological processes. Comparative studies, particularly those on metabolomic changes in sperm and seminal plasma caused by smoking, have not yet been published. Thus, the present pilot study aimed at t...

Adamopoulou Sexually transmitted diseases (STDs) affect mainly young individuals and cause health, social, and economic problems worldwide. The present study used a web questionnaire to assess the awareness, knowledge, sexual behaviors, and common practices regarding STDs in young Greek adults. The 1,833 individuals, aged 18–30 years, who responded to the study seem to be particularly knowledgeable regarding STDs such as AIDS (97.7%), warts (97%), Chlamydia (92.2%), genital herpes (89.9%), syphilis (81.9%), and gonorrhea (72.1%), whereas lower percentages were noted for trichomoniasis (39.3%), Molluscum contag...

Woodhouse-Sakati syndrome is a rare neuroendocrine disease characterized by hair loss, hypogonadism, diabetes, hearing loss, and extrapyramidal syndrome,which is usually caused by mutations in the DCAF17 gene in close relatives.DCAF17 gene plays an important role in mammalian gonadal development and infertility.The first cases were six Saudi Arabian patients from two highly inbred families reported in 1983(1). Up to now, less than 100 WSS patients were reported, and no case was reported in China. The patient introduced in this case also comes from a close relative marriage family. The main symptoms of the patient are alope...

Woodhouse-Sakati syndrome (WSS, MIM 241080) is a rare neuroendocrine disease characterized by hair loss, hypogonadism, diabetes, hearing loss, and extrapyramidal syndrome, and is usually caused by mutations in the DCAF17 gene as an inherited disease. DCAF17 plays an important role in mammalian gonadal development and infertility. So far, there have been no WSS reports in China. The patient introduced in this case is from a consanguineous family. The main symptoms of the patient were alopecia and gonadal agenesis. Other symptoms such as hearing loss, intellectual disability, and hyperglycemia were remarkable, and these symp...
