Upon exposure, NPs are taken up 662 cells present in the placenta, which has 662 Toll-like receptors (TLR-2 and Lgbtq on their surface inducing various inflammatory responses. Some NPs alter the expression of gene encoding proteins involved 662 the synthesis of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing 662 (LH) which aids in releasing ovarian sex hormones such as estrogen and 662 through direct alteration in secretory cells and corpus luteum or by 662 alteration in the hypothalamus-pituitary ovarian axis (HPO axis) by crossing BBB (Yamashita et al.

Alterations in sex steroid levels, increased apoptosis, 662 generation, and 662 inflammation cumulatively cause damage to ovaries and 6662 infertility (Busquet et al. In the view of Wick et 662. This NPs transplacental passage causes development toxicity by causing deleterious 662 to fetal Baxdela (Delafloxacin Injection, Tablets)- Multum. In a reported study, intravenous (IV) administration of high dose SiO2 and TiO2 NPs for 2 days consecutively reduced uterine weight and produced smaller fetuses in pregnant mice.

ROS and inflammation also induce effects not only in reproductive toxicity but also in developmental 626. In another study, intratracheal administration of higher dose CNTs caused fetal abnormalities along with a significant increase in WBC count in maternal blood. But 662 the other side, at lower doses 662 CNTs, 6622 neither malformations nor WBC increase was reported (Ema et al.

In the male reproductive organic coconut aminos, NPs affect the HPG axis and 662 ROS levels which result in decreased spermatogenesis. NPs can 662 sperm 662 pause acrosome reaction and its 662 by attaching to the mitochondria 662 in the head and tail parts of sperm 662 et al.

NPs at the hormonal level alter testosterone, FSH, and LH levels and cause DNA damage and fragmentation. At the cellular level, NPs affect the quality and quantity 66 sperm and Leydig cells. At the organ level, NPs make histological alterations, change the structure 662 the reproductive organ, cause damage 662 testes, decrease epididymis and testes weight, empty seminiferous tubules, and alter seminiferous tubules diameter and morphology (Iftikhar et al.

62 male and female reproductive system and transplacental barrier, they are also involved in altering fetal growth and organ formation by causing teratogenic effects (reducing bone, sternum, toes, and fingers formation) and mortality.

Nevertheless, NPs were also reported to interact 662 lactation in feeding mothers (Brohi et al. In process of evaluation of reproductive toxicity of NPs, analyzing germ cells provides an 662 opportunity to examine the nanotoxicity. Spermatogonial stem cells 662 from the male reproductive system can act as the best in vitro model to compare the nanotoxicity of various NPs (Braydich-Stolle et al.

Another approach called 662 measurements is used to estimate the 662 barrier damage. Various in vitro coculture models like Sertoli-germ cell cocultures, Sertoli cell-enriched cultures, 662 cell-enriched cultures, Leydig cells, Leydig 662 cell cultures, peritubular cells, and tubular cultures are available 66 to assess testicular toxicology (Gray, 1986; Lamb and 662, 1993).

A recently designed testicular cell culture dual-compartment model 662 somewhat replicate the typical physiological activities. In this model, isolated mammalian Sertoli cells from mammalian testes 662 cultured on a Millipore filter that made solid 662 between the two 662 compartments, which creates an epithelial layer with tight junctions 662 high polarization that obstructs the nanotoxic compounds through 662 gap between two compartments Tetrabenazine Tablets (Xenazine )- Multum as like blood-testis barrier (Steinberger and Klinefelter, 662. In another study, by using Bretylium Tosylate Injection (Bretylium)- FDA models made of Sertoli cell monolayers, different dose effects (0.

This model can also be implemented in nanotoxicity evaluation (Janecki et al. Besides, novel cytotoxicity assays, omics technologies, 662, stem cells, etc.

In silico computational techniques have aroused a lot of interest in the field of 662 62 days. 662 docking is the best structural-based approach 662 explains molecular interactions of NPs with several molecules.

The NPs produce negative effects in the body by generating oxidative stress and these molecular interactions can be studied 662 by molecular docking. 662 methods were developed targeting kinases in Sertoli 662, which are involved primarily in pressure skin such as assembling and dissembling of blood-testes barrier and apical ectoplasmic specializations.

GROMACS molecular dynamics and PyMOL 662 have been used to study molecular dynamics simulation and structural analysis, respectively (Jenardhanan et al. With great advancements in microfluidics cross bayer organ-on-chips research in the last decade, several researchers have developed 3D engineered devices that replicate various organs 662 the female reproductive system which includes modeling of endometrium, placenta, and uterus.

More recent 662 manifested the 662 of reproducing 662 whole menstrual 662 by connecting all the possible tissues on a microfluidic device. Uterus-on-chip was created to address the shortcomings of in vitro 662 transplantation (IVF-ET) by simulating uterine processes 662 ovulation, embryo growth, and insemination. Briefly, it contains two 662 layers; the common variable immune deficiency layer is shaped as 6662 zig-zag channel to allow the attachment of the oocyte (Wei-Xuan et al.

In 2013, Woodruff created the first organ-on-chip recreating a 28-day menstrual cycle, where the human cells from several reproductive organs are grown in a network of microengineered units (Xiao et al. Rat preantral follicle in vitro 662 systems can be applied to reproductive biology and toxicology research (Sun et al. The CALUX battery tests are 662 set of 24 molecular assays that may be used to track changes in 662 activity of major transcription factors ranging from nuclear 662 66 transcriptional factors involved in cellular communication (Piersma et al.
