Changes in seminal parameters among Brazilian men between 1995 and 2018.

Aiming to investigate trends in seminal parameter values among Brazilian men between 1995 and 2018, we performed a retrospective analysis of spermograms of couples admitted for infertility testing at UNICAMP/Brazil. For the present study, only the first sample produced by each man was analyzed (9,267 samples). Total motile sperm count (TMSC), percentage of spermatozoa with normal morphology (NM), and sperm concentration after seminal processing (SCA) were considered dependent variables.

[Weight variation in users of the levonorgestrel-releasing intrauterine system, of the copper IUD and of medroxyprogesterone acetate in Brazil].

Background: Assess weight variations in Brazilian users of the 20 microg/day levonorgestrel-releasing intrauterine system (LNG-IUS, Mirena) for comparison with a cohort of users of the TCu 380A intrauterine device (IUD) and a cohort of users of the injectable contraceptive, depot-medroxyprogesterone acetate (DMPA) over a period of five years.

Methods: A total of 163 users of the LNG-IUS, who had the device inserted in 1998, were admitted to the study. At the time of enrollment, each woman was matched by weight (+/- 1 kg) and age (+/- 1 year) to a woman using a TCu 380A IUD and to another woman using DMPA.
