CoronaVac vaccine does not affect ovarian reserve.

OBJECTIVES: In this study, our aim is to investigate the effect of CoronaVac vaccine on ovarian reserve in female patients followed up for infertility. MATERIAL AND METHODS: Our study is a retrospective study. Forty-six infertile patients who received two doses of CoronaVac vaccine one month apart and had not had a previous Covid 19 infection were included in the study. Anti-müllerian hormone (AMH) and folliculometry of 46 patients one month before CoronaVac vaccine and one month after the second dose of vaccine were compared. RESULTS: There was no statistically significant difference in the change of AMH level and follicle number before and after vaccination (respectively p = 0.366; 0.610). CONCLUSIONS: Considering that having a COVID-19 infection has a negative effect on female fertility and causing ovarian damage in recent studies, vaccination is a rational and cost-effective approach to protect ovarian reserve. Knowing that the vaccine does not have a negative effect on fertility may increase the application of the vaccine in women of reproductive age.

Antenatal diagnosis of left atrial isomerism and heterotaxy syndrome in fetus with Meckel-Gruber syndrome.

We aimed to present a fetus with Meckel-Gruber syndrome (MKS) who had left atrial isomerism, heterotaxy syndrome and complete heart block. A 26-year-old healthy female was referred to our clinic in the 23rd week of her pregnancy. The fetus had multiple systemic anomalies including fetal heart. Fetal echocardiography revealed a horizontal liver, left-sided stomach and vena cava interruption with azygos continuation. There was also an apical trabecular ventricular septal defect, aorta and pulmonary artery arising from the left ventricle, pulmonary artery hypoplasia, pulmonary valve stenosis and left atrial isomerism. The heart rate was 46/min, consistent with third-degree atrioventricular block. Multiple anomalies including occipital encephalocele, bilateral polycystic kidneys, cleft lip, cleft palate, and polydactyly were also detected in the obstetric ultrasonography. The pregnancy was terminated in the 23rd gestational week based on the consensus of perinatology council. The autopsy examination confirmed the diagnosis of MKS, left atrial isomerism and heterotaxy syndrome. Although some cardiac defects have been reported previously in MKS fetuses, here we expand the cardiac spectrum of anomalies associated with MKS to include left atrial isomerism and heterotaxy syndrome.
