Association of Trace Elements with Polycystic Ovary Syndrome in Women-A Case-Control Study.
Metabolites ·doi:10.3390/metabo15020079

Objectives: There are still limited or lacking data on the association of trace elements (TEs) with polycystic ovary syndrome (PCOS). This case-control study aimed to determine levels of essential TEs (manganese (Mn), copper (Cu), zinc (Zn)…

Associations of Essential and Non-Essential Trace Elements' Levels in the Blood, Serum, and Urine in Women with Premature Ovarian Insufficiency.
Biological trace element research ·doi:10.1007/s12011-024-04507-8

Premature ovarian insufficiency (POI) is poorly understood, with causes identified in only 25% of cases. Emerging evidence suggests links between trace elements (TEs) and POI. This study is the first to compare concentrations of manganese (…

Polycystic Ovary Syndrome and Endocrine Disruptors (Bisphenols, Parabens, and Triclosan)-A Systematic Review.
Life (Basel, Switzerland) ·doi:10.3390/life13010138

Exposure to endocrine disrupting chemicals (EDCs) can result in alterations of the female reproductive system, including polycystic ovary syndrome (PCOS). The aim of this review was to summarize the knowledge about the association of EDCs (…

Antimüllerian Hormone and Oxidative Stress Biomarkers as Predictors of Successful Pregnancy in Polycystic Ovary Syndrome, Endometriosis and Tubal Infertility Factor
Acta chimica Slovenica ·doi:10.17344/acsi.2020.5864

Oxidative stress in the follicular fluid (FF) is thought to be responsible for the abnormal development of oocytes. In our study patients with polycystic ovarian syndrome (PCOS), endometriosis, and tubal infertility factor (TIF), and health…

Presence and role of stem cells in ovarian cancer.
World journal of stem cells ·doi:10.4252/wjsc.v11.i7.383

Ovarian cancer is the deadliest gynecological malignancy. It is typically diagnosed at advanced stages of the disease, with metastatic sites disseminated widely within the abdominal cavity. Ovarian cancer treatment is challenging due to hig…

Singleton pregnancy outcomes after in vitro fertilization with fresh or frozen-thawed embryo transfer and incidence of placenta praevia.
BioMed research international ·doi:10.1155/2014/431797

The aim of the study was to compare the single pregnancy and neonate outcome after fresh and frozen-thawed embryo transfer in the in vitro fertilization programme (IVF). The study focused on clinical and laboratory factors affecting the abn…

The IMSI procedure improves poor embryo development in the same infertile couples with poor semen quality: a comparative prospective randomized study.
Reproductive biology and endocrinology : RB&E ·doi:10.1186/1477-7827-9-123

BackgroundSperm of poor quality can negatively affect embryo development to the blastocyst stage. The aim of this comparative prospective randomized study was to evaluate the role of an intracytoplasmic morphologically selected sperm inject…

Outcome of frozen-thawed blastocysts derived from gonadotropin releasing hormone agonist or antagonist cycles.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-006-9051-3

PurposeThe aim of this retrospective study was to compare the outcome of frozen-thawed blastocysts derived from the cycles using controlled ovarian stimulation with GnRH agonists vs. GnRH antagonists.MethodsSurvival, pregnancy and cumulativ…

Sperm single-stranded DNA, detected by acridine orange staining, reduces fertilization and quality of ICSI-derived embryos.
Journal of assisted reproduction and genetics ·doi:10.1023/a:1016006509036

PurposeThe aim of this study was to evaluate the effect of sperm single-stranded DNA, detected by acridine orange (AO), and classical sperm parameters on embryonic quality after ICSI.MethodsBefore ICSI, the spermatozoa of 183 infertile pati…
