BackgroundOur goal was to investigate immunoglobulin G1 (IgG1) and immunoglobulin G3 (IgG3) antibody responses to Chlamydia trachomatis proteins Pgp3 and Hsp60 in males of subfertile couples and to explore the association of these antibodie…

BackgroundOur goal was to investigate IgG1 and IgG3 antibody responses to Chlamydia trachomatis proteins Pgp3 and Hsp60 in women with tubal factor infertility (TFI). Our goal was to determine the role of these biomarkers in the diagnosis of…

BACKGROUND: There is concern that assisted reproductive technology (ART) may increase ovarian cancer risk, but previous studies are inconclusive. We compared ovarian cancer risk for women who gave birth after ART vs natural conception. MET…

OBJECTIVES: To investigate whether risks of stillbirth and neonatal death differ after fresh embryo transfers (fresh-ETs) and frozen embryo transfers (frozen-ETs) compared with singletons conceived without medical assistance. DESIGN: A pop…

INTRODUCTION: The incidence of ectopic pregnancy is up to four times higher after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) than in spontaneous pregnancies, and the risk of ectopic pregnancy is increased by tubal fa…

STUDY QUESTION: Is a low (<1.0 μg/L) or moderately low (1.0-1.9 μg/L) serum anti-Müllerian hormone (AMH) level a risk factor for early pregnancy loss in IVF/ICSI with a fresh or frozen-thawed embryo transfer (ET)? SUMMARY ANSWER: A low or …

PURPOSE: Pentraxin 3 (PTX3) is a locally secreted, quicker responsive pro-inflammatory protein than C-reactive protein (CRP). We evaluated the value of PTX3 in the prediction of ovarian hyperstimulation syndrome (OHSS), a severe complicatio…

OBJECTIVE: To study reproductive outcomes, and pregnancy and delivery complications after conservative or operative treatment of rectovaginal endometriosis during long-term follow-up. DESIGN: Retrospective cohort study. SETTING: Universit…

INTRODUCTION: The association between endometriosis and breast cancer is unclear. We assessed the risk of breast cancer in women with surgically verified endometriosis, with special focus on the age at cancer diagnosis, time from endometrio…

STUDY QUESTION: Is all-cause and cause-specific mortality increased among women with surgically verified endometriosis? SUMMARY ANSWER: The all-cause and cause-specific mortality in midlife was lower throughout the follow-up among women wi…

Chlamydia trachomatis IgG antibody testing (CAT) has been used as a screening test for tubal factor infertility (TFI), but as the CAT is only a marker of a past exposure to C. trachomatis and not of late sequelae, the positive predictive va…

We assessed the association of surgically verified endometriosis and risk of non-gynecological cancers according to the type of endometriosis (i.e., ovarian, peritoneal and deep infiltrating endometriosis). All diagnoses of endometriosis co…

OBJECTIVE: To assess the risks of gynecologic cancer according to the type of endometriosis in women with surgically verified endometriosis. METHODS: This is a population-based study of women with surgically verified endometriosis retrieve…

Urinary tract endometriosis (UTE) is a rare form of deep infiltrating endometriosis. We studied the operative treatment of UTE and evaluated postoperative recurrences and fertility outcomes. This is a retrospective cohort study of 53 women …

BACKGROUND: Regulation of immune responses is critical for controlling inflammation and disruption of this process can lead to tissue damage. We reported that CXCL13 was induced in fallopian tube tissue following C. trachomatis infection. H…

Endometriosis-associated infertility is poorly treatable with various forms of surgery. Therefore, assisted reproduction techniques (ARTs), such as controlled ovarian hyperstimulation, intrauterine insemination, or in vitro fertilization, a…

To assess and compare the gynaecological consequences of the use of 2 antioestrogens we examined 167 postmenopausal breast cancer patients before and during the use of either tamoxifen (20 mg/day, n = 84) or toremifene (40 mg/day, n = 83) a…

OBJECTIVE: To investigate the impact of an IVF program on serum levels of tumor markers CA 125, tumor-associated trypsin inhibitor, free hCG beta-subunit, and free glycoprotein hormone alpha-subunit. DESIGN: A prospective controlled clinic…

BACKGROUND: To compare intrauterine insemination (IUI), direct intraperitoneal insemination (DIPI), and timed-intercourse (TI), each combined with superovulation, in the treatment of couples with unexplained infertility, including couples w…

Direct intraperitoneal or intrauterine insemination in combination with superovulation was used randomly as the treatment of infertility that was unexplained or due to male subfertility or mild endometriosis in 124 couples during 326 cycles…
