Pregnancy is accompanied by changes in thyroid function, but limited data are available on these changes in the very first weeks of pregnancy. Yet, T(4) plays a major role in implantation and early fetal development. We sought to determine thyroid function during this period and during the first trimester, in pregnancies achieved by assisted reproductive technology. Furthermore, the thyroid hor...

BACKGROUND Women with hyper-and hypothyroidism are at increased risk for infertility and adverse pregnancy outcomes. Whether in women considered euthyroid thyroid function (TSH values) and thyroid autoimmunity (thyroid antibodies) influence in vitro fertilization (IVF) cycle outcome has, however, remained controversial. Any such effect should be easily visible in women with low functional ovari...

BACKGROUND Thyroid dysfunction is the most common autoimmune endocrine disorder in women of reproductive age, and is associated with menstrual irregularities, anovulation and infertility. Whether it is thyroid function or thyroid autoimmunity that affects functional ovarian reserve (FOR, i.e., the small growing ovarian follicle pool) reflected in anti-Müllerian hormone (AMH) has, however, remai...

The persistent presence in plasma of medium to high levels of IgG and/or IgM class anticardiolipin antibodies (aCL) and/or the lupus anticoagulant (LAC) is associated with both “recurrent pregnancy loss” and venous and arterial thrombosis. This clinicoserological entity, first described in the early eighties in patients with systemic lupus erythematosus was termed the antiphospholipid syndrome ...

OBJECTIVE To examine whether the concentrations of maternal serum TSH and free thyroxine (fT4) through pregnancy, the presence of thyroid autoimmunity (TAI) or the dose of levo-thyroxine (LT4) replacement can predict the occurrence of maternal or fetal/neonatal complications in pregnant women treated for maternal hypothyroidism. DESIGN The study included 92 women with singleton pregnancies an...

Background Preconception care means interventions required for maternal and fetal health care and detection of pre-pregnancy risk factors. Some risk factors that have a significant effect on the outcome of pregnancy can be detected and controlled before pregnancy. The present study aimed to determine the prevalence of pre-pregnancy risk factors, and its relationship with preconception care in I...
