The aim of this study was to examine more closely the interaction between thyroid function and pituitary--ovarian axis in infertile women. In 185 infertile women without clinical signs of thyroid dysfunction, TRH-tests (TSH basal and 30 min after 200 micrograms TRH i.v.) were performed in the early follicular phase in addition to routine hormonal checks (gonadotrophins, oestradiol, DHEAS, testosterone, prolactin). The women were classified as euthyroid (n = 74; TSH stim 5-20 mU/l), latent hyperthyroid (n = 31; TSH stim less than 5 mU/l), and preclinical hypothyroid (n = 80; TSH stim greater than 20 mU/l). From frozen serum, the following determinations were performed: TSH IRMA, laevothyroxine (T4), thyroxine binding globulin (TBG), microsomal (Mab) and thyroglobulin (Tab) antibodies. Various correlations between the thyroid parameters and the pituitary--ovarian axis were demonstrated. With increasing TBG concentrations, the interval between menses decreased. Overall and spontaneous pregnancy rates were highest in women with normal (less than 75th perc.) basal and stimulated TSH, high (greater than 75th perc.) T4 and low (less than 25th perc.) Mab. Women with normal Tab or high TBG experienced the highest delivery rate (77 versus 30%), while in women with low Tab or high Mab abortion and tubal pregnancies were most frequent. As only 25 women exhibited elevated Mab (greater than 500 U/ml) or Tab (greater than 200 U/ml) which correlated with elevated TSH and normal T4, the routine determination of thyroid antibodies was not necessary. The TRH-test, however, should be included in infertility work-up.

Primary ovarian insufficiency (POI) is a disease defined as a reduction in ovarian function under the age of 40 and represents the main cause of female infertility. In recent years, many genetic mutations associated with POI have been identified using high-throughput sequencing technology. However, one big challenge today is to determine the disease-causing gene associations through functional assessment.

Classified as endocrine disrupting chemicals (EDCs), perchlorate, nitrate, and thiocyanate have been implicated with obesity and reproductive disorders. This study used three cycles of the National Health and Nutrition Examination Survey (NHANES 2013-2018); 813 women of reproductive age were finally included. We used multivariable logistic regression to analyze the associations between the three anions and obesity and infertility.

Methods: This retrospective cohort study analyzed 7378 singleton births (2643 non-ART, 4219 FET, 516 FreshET) from 2013 to 2022. Outcomes were compared using inverse probability weighting regression adjustment, with adjustment for maternal factors.

Oxidative stress (OS) is established as a key factor in the etiology of both male and female infertility, arising from an imbalance between reactive oxygen species (ROS) production and the endogenous antioxidant (AOX) defenses. In men, OS adversely affects sperm function by inducing DNA damage, reducing motility, significantly impairing sperm vitality through plasma membrane peroxidation and loss of membrane integrity, and ultimately compromising overall sperm quality. In women, OS is implicated in various reproductive disorders, including polycystic ovary syndrome, endometriosis, and premature ovarian failure, leading to diminished oocyte quality, disrupted folliculogenesis, and poorer reproductive outcomes.

Background: Infertility constitutes a leading reproductive health problem with profound psychosocial outcomes, including elevated depressive symptoms that compromise quality of life (QoL). While the literature has suggested social support as a protective psychological mechanism, its role in depressive symptoms and QoL among women with infertility remains underexplored. This study aimed to examine the moderating effect of perceived social support on the relationship between depressive symptoms and QoL among South Korean women experiencing infertility.
