Exposure of Porcine Oocytes to Methylparaben During In Vitro Maturation Alters the Expression of Genes Involved in Cumulus Cell Expansion and Steroidogenesis, Decreasing Hyaluronic Acid and Progesterone Synthesis.

Parabens are widely used because of their antimicrobial properties in drugs, cosmetics, and food; however, it has been reported that methylparaben may adversely influence female reproduction. Methylparaben decreases oocyte in vitro maturation at a maturation inhibition concentration 50 of 780.31 μM but also decreases oocyte viability at a lethal concentration 50 of 2028.

In vitro exposure of porcine spermatozoa to methylparaben, and propylparaben, alone or in combination adversely affects sperm quality.

Parabens (PBs) are widely used in the cosmetic, pharmaceutical, and food industries as preservatives of products. Because of its great use, humans and other organisms are highly exposed daily. However, little is known about the effect of PBs on male infertility.

Effects of methylparaben on in vitro maturation of porcine oocytes.

Parabens (PBs) are compounds widely used in industry for food and personal care products as antimicrobials and preservatives. Their indiscriminate use has resulted in their detection in different ecosystems so that humans and other organisms are highly exposed. Methylparaben (MePB), compared with other PBs, is mostly detected in food, personal care and baby care products.
