Phthalates in Albumin from Human Serum: Implications for Assisted Reproductive Technology

Area of Science:

• Reproductive biology
• Toxicology
• Biochemistry

Background:

• Human serum albumin (HSA) is crucial for assisted reproduction technologies (ART).
• HSA is sourced from human blood stored in polyvinyl chloride (PVC) bags containing di-2-ethylhexyl phthalate (DEHP).
• DEHP can leach into blood and co-purify with HSA.

Purpose of the Study:

• To review the role of HSA in ART.
• To examine HSA production from whole blood.
• To highlight the potential impact of phthalate contamination in HSA on gametes during in vitro procedures.

Main Methods:

• Literature review of HSA function and production.
• Analysis of phthalate leaching from PVC blood bags.
• Review of studies on phthalate effects on gametes and embryos.

Main Results:

• DEHP and its metabolite MEHP are endocrine disruptors.
• Phthalates can contaminate HSA during blood storage.
• Studies indicate adverse effects of phthalates on gametes in animal IVF models.

Conclusions:

• Phthalate contamination of HSA used in ART is a potential concern.
• This contamination may adversely affect ART success rates.
• Further examination of phthalate levels in HSA and their impact on human ART is warranted.
