In aquatic ecosystems, progesterone (P4) and synthetic progestins (gestagens) originate
from excretion by humans and livestock. Synthetic progestins are used for contraception and …

Around 20 progestins (also called gestagens, progestogens, or progestagens) are used
today in assisting a range of medical conditions from endometrial cancer to uterine bleeding …

The aim of this study was to investigate the effects of progestins on the sex differentiation of
zebrafish by measuring the sex ratio and transcriptions of genes related to sex differentiation …

The aquatic environment is polluted with thousands of chemicals. It is currently unclear
which of these pose a significant threat to aquatic biota. The typical exposure scenario is …

The aim of this study was to assess the long-term effects of synthetic progestin
norethindrone (NET) on the growth, reproductive histology, and transcriptional expression …

Synthetic progestins have become widespread environmental contaminants and may cause
adverse effects on fish. In the present study, we investigated the effects of levonorgestrel …

Environmental exposure of fish to steroid hormones through wastewater and agricultural
runoff may pose a health risk. Thus far, ecotoxicological studies have largely been focused …

Progestins and estrogens are widespread in various aquatic environments and their
potential endocrine disruption effects to aquatic organisms have drawn growing concern …

Synthetic progestins act as endocrine disrupters in fish but their risk to the environment is not
sufficiently known. Here, we focused on an unexplored antiandrogenic progestin …

Farms and wastewater treatment plants (WWTPs) are important sources of endocrine
disruptors, which may have potential adverse effects on the nearby receiving river and …
