Introduction: Microbiota in the human body are closely related to human diseases. Female urogenital tract and rectal microbes have been considered as important factors affecting female pregnancy, but the mechanism is unknown.

Methods: Cervical, vaginal, urethral, and rectal swabs were collected from 22 infertile patients and 10 controls, and follicular fluid was extracted from 22 infertile patients. The microbial composition of different sampling sites of infertile patients was examined. By comparing the microbial composition difference between infertile patients and controls and combining bioinformatics methods to analyze the potential impact of the female urogenital tract (cervical, vaginal and urethral) and rectal microbial diversity on female infertility and pregnancy outcomes.

Results: predominated in the female urogenital tract, but its abundance decreased in infertile patients, whereas the abundance of and increased. The microbial changes in the urethra had the same trend as that in the vagina. Compared with healthy controls, the cervical and rectal microbial diversity of infertile patients were significantly increased and decreased, respectively. There might be interactions between microbes in different parts of female. was enriched in the urogenital tract and rectum of infertile patients, and has a good predictive effect on infertility. Compared with infertile patients, was enriched in the vagina, urethra, and intestine of the control group. in follicular fluid might be associated with Non-pregnancy.

Conclusion: This study found that the microbial composition of infertile patients was changed compared with that of healthy people. The translocation of Lactobacillus between the rectum and urogenital tract might play a protective barrier role. The changes of and might be related to female infertility or pregnancy outcome. The study provided a theoretical basis for the future treatment of female infertility from the perspective of microorganisms by detecting the microbial changes associated with female infertility.

Background: Numerous pathogenic variants causing human oocyte maturation arrest have been reported on the primate-specific TUBB8 gene. The main etiology is the dramatic reduction of tubulin α/β dimer, but still large numbers of variants remain unexplained.

Methods: Using microinjection mRNA and genome engineering to reintroduce the conserved pathogenic missense variants into oocytes or in generating TUBB8 variant knock-in mouse models, we investigated that the human deleterious variants alter microtubule nucleation and spindle assembly during meiosis.

Celiac disease is one of the most common lifelong autoimmune disorders and is currently understood as a genetically determined immune intolerance to gluten. In genetically predisposed individuals, the consumption of gluten, along with additional environmental factors, triggers an immunological reaction in the small intestinal epithelium, leading to the destruction of the mucosal architecture with villous atrophy. This can be asymptomatic, but may also cause a wide range of symptoms and lead to systemic complications, such as osteoporosis or infertility.

Background: Endometriosis, a prevalent chronic gynecological condition, is frequently associated with infertility and pelvic pain. Despite numerous studies indicating a correlation between epigenetic regulation and endometriosis, its precise genetic etiology remains elusive. Methyltransferase-like 14 (METTL14), a crucial component of the N6-methyladenosine (mA) RNA methyltransferase complex and an RNA binding scaffold, is known to play a pivotal role in various human diseases.

Background: Intrauterine insemination (IUI) is an effective and inexpensive method of managing patients with unexplained and male factor infertility. It is attempted before proceeding to more invasive assisted reproductive techniques such as fertilisation and intracytoplasmic sperm injection. Numerous semen parameters have been assessed to indicate successful outcomes with IUI.
