Background: Integration of family planning services (FPS) into human immunodeficiency virus (HIV) care for HIV-infected women is an important aspect of the global prevention of mother-to-child transmission (PMTCT) strategy. We assessed the integration of FPS into routine care of HIV-infected mothers by evaluating the uptake and barriers of contraception and PMTCT services.

Methods: We conducted an interventional study using the interrupted time series approach in the health care facilities located in Yaounde, Cameroon.

Article Synopsis
  • Human sperm DNA has a unique chromatin structure that requires specialized extraction methods compared to somatic cells.
  • The study compared three sperm DNA extraction techniques: modified guanidinium thiocyanate method (method A), phenol-chloroform method (method B), and TianGen kit method (method C).
  • Results showed that method A produced the highest quantity and purity of DNA and was more reliable for amplifying certain genes, making it the preferred choice for sperm DNA extraction, especially for methylation assays.
