Association of In Utero Exposure to Maternal Smoking with Reduced Semen Quality and Testis Size in Adulthood: A Cross-Sectional Study of 1,770 Young Men from the General Population in Five European Countries
Tina Kold Jensen,Niels Jørgensen,Margus Punab,Trine B. Haugen,J. Suominen,Birute Zilaitiene,Antero Horte,Anne-Grethe Andersen,Elisabeth Carlsen,Øystein Magnus,Valentinas Matulevičius,Ingrid Nermoen,Matti Vierula,Niels Keiding,Jorma Toppari,Niels E. Skakkebæk +15 more
TL;DR: Maternal smoking may have long-term implications for the reproductive health of the offspring, and this is another good reason to advise pregnant women to avoid smoking.
Journal ArticleDOI
Varicocele Is Associated with Impaired Semen Quality and Reproductive Hormone Levels: A Study of 7035 Healthy Young Men from Six European Countries.
Jakob Damsgaard,Ulla Nordström Joensen,Elisabeth Carlsen,Juris Erenpreiss,Martin Blomberg Jensen,Martin Blomberg Jensen,Valentinas Matulevičius,Birute Zilaitiene,Inge A. Olesen,Antti Perheentupa,Margus Punab,Andrea Salzbrunn,Jorma Toppari,Helena E. Virtanen,Anders Juul,Niels E. Skakkebæk,Niels Jørgensen +16 more
TL;DR: The presence and increasing grade of varicocele is adversely associated with semen quality and reproductive hormone levels in young men from the general population.
Journal ArticleDOI
Higher than expected prevalence of congenital cryptorchidism in Lithuania: a study of 1204 boys at birth and 1 year follow-up
Romualdas Tomas Preikša,Birute Zilaitiene,Valentinas Matulevičius,N E Skakkebaek,J H Petersen,Niels Jørgensen,Jorma Toppari +6 more
TL;DR: No correlation between cryptorchidism at birth and maternal age, birth order or mode of delivery was demonstrated in this study, but paternal body mass index <20 kg/m2 was found to be a significant risk factor.
Journal ArticleDOI
Regional differences in semen qualities in the Baltic region.

TL;DR: The sperm counts of the Estonian and Lithuanian men investigated here are higher than recently shown for Norwegian, Danish, Estonia and Finnish men, and comparisons should be cautiously drawn as the groups are not completely comparable.
Journal ArticleDOI
Study in 1790 Baltic men: FSHR Asn680Ser polymorphism affects total testes volume
Marina Grigorova,Margus Punab,Olev Poolamets,Siim Sõber,Vladimir Vihljajev,Birutė Žilaitienė,J. Erenpreiss,Valentinas Matulevičius,I. Tsarev,Maris Laan +9 more
TL;DR: In conclusion, the study in 1790 Baltic men shows statistically highly significant association of the FSHR Asn680Ser with total testes volume and supportive association with serum reproductive hormone levels indicative to the functional effect of the alternative F SHR variants on male reproductive physiology.
