Journal ArticleDOI
Overt and Subclinical Hypothyroidism Complicating Pregnancy
Marcos Abalovich,S. Gutierrez,Graciela Alcaraz,G. Maccallini,Antonio G. García,Oscar Levalle +5 more
TL;DR: The results show that the adequate treatment of hypothyroidism during gestation minimizes risks and generally, makes it possible for pregnancies to be carried to term without complications.
Journal ArticleDOI
Subclinical hypothyroidism and thyroid autoimmunity in women with infertility.
Marcos Abalovich,Laura Mitelberg,Carlos Allami,S. Gutierrez,Graciela Alcaraz,Patricia Otero,Oscar Levalle +6 more
TL;DR: The results support thyroid screening in women with reproductive failure, and observed a higher prevalence of SH, but not of TAI, in patients with infertility.
Journal ArticleDOI
Effect of rosiglitazone on insulin resistance, growth factors, and reproductive disturbances in women with polycystic ovary syndrome.
TL;DR: Associated with the decrease in LH, rosiglitazone improved insulin-resistance parameters and normalized the menstrual cycle, which suggests that this drug could improve the endocrine-reproductive condition in insulin-resistant women with PCOS.
Journal ArticleDOI
Hypothalamic-Pituitary-Testicular Axis and Seminal Parameters in Hyperthyroid Males
Marcos Abalovich,Oscar Levalle,R. Hermes,H. Scaglia,C. Aranda,C. Zylbersztein,A. Oneto,D. Aquilano,S. Gutierrez +8 more
TL;DR: The results confirm that hyperthyroidism causes marked alterations of the gonadotropic and PRL axis and dramatically affects spermatic function and bioT measurement was useful to identify hypoandrogenism in these patients in spite of the high concentration of total testosterone.
Journal ArticleDOI
The relationship of preconception thyrotropin levels to requirements for increasing the levothyroxine dose during pregnancy in women with primary hypothyroidism.
Marcos Abalovich,Graciela Alcaraz,Jessica Kleiman-Rubinsztein,María Magdalena Pavlove,Cecilia Cornelio,Oscar Levalle,S. Gutierrez +6 more
TL;DR: It is suggested that in women with hypothyroidism who are planning to become pregnant, serum TSH levels should be in the normal range but should not be greater than about 1.2 mIU/mL.
