Toxicity of TCDD in the mouse antral follicle
… growth, and atresia of intact mouse antral follicles in vitro. Interestingly, TCDD has been shown to act mainly through binding to the aryl hydrocarbon receptor (AHR) in other tissues, and the AHR has been identified as an important factor in ovarian function. Thus, these studies were …

ULTRASOUND CHARACTERIZATION OF ANTRAL FOLLICLE DYNAMICS ACROSS THE ADIPOSITY SPECTRUM
… hormone pulse amplitude in addition to lower follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH) production, albeit controversial. These endocrine aberrations likely reflect alterations in antral ovarian follicle development, but this has never been systematically evaluated in …

Associations of parental age, socioeconomic status, antral follicle count with assisted reproductive technology treatment outcomes
… age, low socio-economic status (SES), and antral follicle count (AFC) are significantly and independently associated with adverse ART outcomes. There is little known about their interaction effects with an unhealthy lifestyle on adverse ART outcomes. This PhD study investigated the …

The effects of adult exposure to genistein on female reproductive outcomes
… is because the ovary’s main functional unit, the follicle, is responsible for the production of sex steroid hormones and consists of the oocyte necessary for fertilization. In the adult ovary, the follicle is present in all stages ranging from the immature primordial follicle to the most mature …

Equol inhibits growth, induces atresia, and inhibits steroidogenesis of mouse antral follicles
… which could in turn influence ovarian follicle growth. However, no studies have examined the direct effects of equol on intact antral follicles, which are responsible for sex steroid synthesis and further development into ovulatory follicles. The present study tested the hypothesis that …

Mechanisms by which di(2-ethylhexyl) phthalate and mono(2-ethylhexyl) phthalate disrupt ovarian folliculogenesis and steroidogenesis
… are folliculogenesis and steroidogenesis. Follicles are the functional units of the ovary containing the oocyte required for ovulation and fertilization and somatic cells responsible for synthesizing sex steroid hormones. Folliculogenesis is the process by which follicles undergo several …

The effects of an environmentally relevant phthalate mixture on female reproduction
… are born with a finite pool of primordial follicles, and the size of primordial follicle pool determines the reproductive lifespan. To form the finite pool of primordial follicles, germ cells must undergo mitosis, formation of germ cell nests, meiosis, and germ cell nest breakdown. Any …

Endocrine markers of ovarian function: Clinical and biological aspects with focus on Anti Müllerian hormone
… potential are often requested. Currently the antral follicle count and the Anti Müllerian Hormone (AMH) level are considered to be the most predictive markers. The two markers roughly describe the same issue as they are both related to certain developmental stages of the folliculogenisis. …

Mechanism of Bisphenol A toxicity in adult mouse ovarian antral follicles
… endocrine responsive processes such as ovarian follicle growth and steroidogenesis. Follicles are the functional units of the ovary, responsible for ovulating an oocyte and producing sex steroid hormones during steroidogenesis. Follicles grow and develop from primordial, primary, pre-antral, and …

Management and nutrition of the replacement gilt.
… feed restriction reduced the number of medium follicles present on the ovaries of 161- and 175-day old gilts, as well as the proportion of oocytes reaching Metaphase II in vitro. However, feeding level during the 14 days prior to ovary collection had the greatest effect on follicular growth and …

Toxicity and detoxification of imidacloprid in mouse ovarian follicles
… to test the hypothesis that IMI causes ovarian follicle toxicity via acetylcholine pathways and the ovary itself contributes to this ovotoxicity using its metabolic machinery. In Chapter 3, I compared the effects of IMI and DNI on antral follicle physiology in vitro. Antral follicles were …

The transgenerational effects of Di(2-ethylhexyl) phthalate on female reproduction in mice
… the ovary is a heterogeneous organ composed of follicles, oocytes, corpora lutea, and interstitial tissue. The primary roles of the ovary are to produce sex steroid hormones and maintain a steady stream of growing follicles. Normal sex steroid hormone production by the mature follicles is …

The immediate and long-term consequences of temporary exposure during adulthood to di(2-ethylhexyl) phthalate and diisononyl phthalate on female reproduction
… number of oocytes in the form of the primordial follicle pool. Primordial follicles are composed of an oocyte surrounded by supporting somatic cells. Activated primordial follicles will grow through the primary, preantral, and antral follicle stages before ovulating. Proper maintenance of this …

Trace mineral supplementation in cattle: Implications in heifer development, reproductive performance, and fetal programming
… there was no difference (P = 0.60) in liver Mn. Antral follicle count and ovarian size did not differ (P ≥ 0.51) due to treatment. Throughout development, number of heifers cycling was lesser (P < 0.01) for MM than CON heifers. However, there was no difference (P ≥ 0.19) in reproductive tract …
