Abstract
Estrogen excess in females has been linked to a diverse array of chronic and acute diseases. Emerging research shows that exposure to estrogen-like compounds such as bisphenol S leads to increases in 17β-estradiol levels, but the mechanism of action is unclear. The aim of this study was to reveal the underlying signaling pathway-mediated mechanisms, target site and target molecule of action of bisphenol S causing excessive estrogen synthesis. Human ovarian granulosa cells SVOG were exposed to bisphenol S at environmentally relevant concentrations (1 μg/L, 10 μg/L, and 100 μg/L) for 48 h. The results confirms that bisphenol S accumulates mainly on the cell membrane, binds to follicle stimulating hormone receptor (FSHR) located on the cell membrane, and subsequently activates the downstream cyclic adenosine monophosphate/protein kinase A (cAMP/PKA) signaling pathway, leading to enhanced conversion of testosterone to 17β-estradiol. This study deepens our knowledge of the mechanisms of environmental factors in pathogenesis of hyperestrogenism.

Abstract
Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility. Inadequate understanding of the ovulation drivers hinders PCOS intervention. Herein, we report that follicle stimulating hormone (FSH) controls follicular fluid (FF) glutamine levels to determine ovulation. Murine ovulation starts from FF-exposing granulosa cell (GC) apoptosis. FF glutamine, which decreases in pre-ovulation porcine FF, elevates in PCOS patients FF. High-glutamine chow to elevate FF glutamine inhibits mouse GC apoptosis and induces hormonal, metabolic, and morphologic PCOS traits. Mechanistically, follicle-development-driving FSH promotes GC glutamine synthesis to elevate FF glutamine, which maintain follicle wall integrity by inhibiting GC apoptosis through inactivating ASK1-JNK apoptotic pathway. FSH and glutamine inhibit the rapture of cultured murine follicles. Glutamine removal or ASK1-JNK pathway activation with metformin or AT-101 reversed PCOS traits in PCOS models that are induced with either glutamine or EsR1-KO. These suggest that glutamine, FSH, and ASK1-JNK pathway are targetable to alleviate PCOS.

Abstract
FSH-FSHR interaction is critical for folliculogenesis, spermatogenesis and progression of several cancers. Therefore, FSHR is an attractive target for fertility regulation and cancer therapeutics. Based on homology and structural analysis of hFSH-FSHR(ECD) complex, a minimal continuous stretch within FSHβ seat-belt loop (FSHβ (89-97)) was identified to be crucial for FSHR interaction. The ability of FSHβ (89-97) peptide to neutralize FSHR activity was evaluated by a panel of in vitro and in vivo experiments. The synthetic peptide significantly inhibited binding of [125I]-FSH to rat Fshr as well as FSH-induced cAMP production. In immature rats, FSHβ (89-97) peptide administration reduced FSH-mediated increase in ovarian weight. The peptide inhibited transition of follicles from pre-antral to antral stage and hindered the cell cycle progression of granulosa cells beyond G0/G1 phase. In adult rats, administration of the peptide inhibited estradiol synthesis and significantly perturbed folliculogenesis.

Melphalan, alone or conjugated to an FSH-β peptide, kills murine testicular cells in vitro and transiently suppresses murine spermatogenesis in vivo. Theriogenology 2014; 82:152-9.

Abstract
New approaches to sterilizing male animals are needed to control captive and wild animal populations. We sought to develop a nonsurgical method of permanent sterilization for male animals by administering the gonadotoxicant melphalan conjugated to peptides derived from the β-chain of FSHβ. We hypothesized that conjugating melphalan to FSHβ peptides would magnify the gonadotoxic effects of melphalan while minimizing systemic toxicity. The ability of conjugates of melphalan and FSHβ peptides to kill murine testicular cells was first tested in vitro in a three-dimensional testicular cell coculture system. In this system, melphalan caused considerable cell death as measured both by increases in lactate dehydrogenase concentrations in the culture supernatant and direct visualization of the cultures. Of the conjugates tested, melphalan conjugated to a 20-amino acid peptide derived from human FSHβ consisting of amino acids 33 to 53 (FSHβ (33-53)-melphalan) was very potent, with cell cytotoxicity and lactate dehydrogenase release roughly one-half that of melphalan. The effects of melphalan and FSHβ (33-53)-melphalan on spermatogenesis were then tested in vivo in mature C56Bl/6 male mice. Four weeks after intraperitoneal injection, all mice treated with either FSHβ (33-53)-melphalan or melphalan had approximately 75% reductions in testicular spermatid counts compared with control animals. Testicular histology revealed significant reduction in mature spermatids and spermatocytes in most tubules. However, 12 weeks after the injection, testicular spermatid counts and histology were similar to controls, except in one animal receiving FSHβ (33-53)-melphalan that had no apparent spermatogenesis. We conclude that melphalan and FSHβ (33-53)-melphalan are potent gonadotoxicants in male mice resulting in marked suppression of spermatogenesis 4 weeks after a single intraperitoneal injection. However, this effect is transient in most mice as spermatogenesis is similar to control animals 12 weeks after drug administration. Melphalan or FSHβ (33-53)-melphalan may be useful for the temporary control of fertility in male animals, but additional research will be needed to develop a single dose method of permanent sterilization for male animals.

Abstract
The involvement of serum anti-ovarian autoantibodies (AOA) in ovarian pathology still remains controversial. In some cases of clinically patent ovarian failure, there seems to be a causal relationship between AOA and the ovarian disease. In patients with various organ-specific or systemic autoimmune diseases, or with unexplained, repeated reproductive failure, but otherwise normal ovarian function, it is even more difficult to determine the significance of AOA for several reasons: i) AOA recognize many different antigenic targets in the ovary ii) the antiovarian response may be transient or variable with time iii) the presence of AOA does not imply their aetiopathogenic role in the disease. The present paper reviews the clinical significance of AOA based on their ovarian targets as far as they have been identified until now.

Abstract
The purpose of this study was to identify autoantigens contained in human ovary extracts. Serum samples from 36 infertile women with anti-ovary antibodies as detected with an ELISA technique were tested in Western blot against human ovary extracts. A reactive protein with a molecular mass matching that of the FSH was detected in 34 cases. These serum samples also reacted strongly in Western blot and ELISA with purified FSH and, in immunofluorescence, with pituitary cells. Using the Pepscan approach, with overlapping peptides matching the amino acid sequence of the human FSH beta-chain, several immunoreactive regions were evidenced. The 78-93 amino acid sequence of the human FSH beta-chain appeared as one of the major epitopes. Synthetic peptides of this region were prepared and demonstrated to react with human serum samples from women with anti-ovary antibodies. These data demonstrate that FSH can be an autoantigen, recognized by autoantibodies associated with infertility.

Abstract
We have previously reported that synthetic peptide amides corresponding to subdomains of the human FSH 3-subunit, hFSH-beta-(33--53) and hFSH-beta-(81--95), interact with the external domain of the FSH receptor in two in vitro model systems. Consistent with these in vitro observations, we found that intraperitoneal (i.p.) administration of each of these peptides prolonged vaginal estrus in normally cycling mice in vivo. Both hFSH-beta-(33--53) and hFSH-beta-(81--95) contain cysteine (Cys) residues with free sulfhydryl groups of potential significance in receptor interactions. To assess the possible involvement of these groups in the in vivo effects of hFSH-beta-(33--53) and hFSH-beta-(81--95), synthetic peptide analogs were prepared in which all Cys residues were replaced with serine (Ser). In the present study, we demonstrate that the in vivo effect of hFSH-beta-(33--53) on the mouse estrous cycle, extension of vaginal estrus, was not changed by substitution of Cys-51 with Ser. In contrast, mice receiving the Ser-substituted analog of hFSH-beta-(81--95) had normal estrus stages, but were arrested in diestrus. hFSH-beta-(33--53)-(81--95), a linear peptide encompassing both domains, also prolonged vaginal estrus. The Ser-substituted analog of this peptide, however, prolonged vaginal estrus in some of the mice tested and induced cycle arrest at diestrus in others. hFSH-beta-(90--95), the active subdomain at the C-terminus of hFSH-beta-(81--95), extended vaginal estrus, but diestrus stages were of normal duration. Its Ser-substituted analog, however, prolonged the estrus stage of the majority of mice treated, but induced diestrus arrest in some. The differing responses to these peptides are presumably due to interactions of the synthetic peptides with different regions of the FSH receptor. This further suggests that one consequence of ligand interaction with multiple receptor binding domains may be variable effects on ovarian function, and that Cys to Ser analogs may have value in the design of a novel class of synthetic peptides capable of fertility regulation and control.
