Abstract
Androgen concentrations in follicular fluid samples collected from patients undergoing in vitro fertilization (IVF) may provide useful clinical indicators. This study aimed to analyze possible associations of the androgen levels in follicular fluid and blood plasma in patients with diminished ovarian reserve (POR) in IVF programs. Cross-sectional study with a parallel group design, conducted in 2019–2021, enrolled 300 patients with infertility, aged 18–42 years, applying for assisted reproduction involving IVF/intracytoplasmic sperm injection and embryo transfer. The androgen profiles of blood plasma and follicular fluid were determined by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Androgen concentrations in blood plasma and follicular fluid, particularly those of dehydroepiandrosterone (DHEA-S), androstenedione and total testosterone, significantly correlated. The results implicate androgen levels in blood plasma and follicular fluid as early markers of POR in patients with infertility.

Gonadotropin Stimulation Has Only a Limited Effect on the Concentration of Follicular Fluid Signalling Proteins: An Antibody Array Analysis. Int J Reprod Med 2021; 2021:2906164. [PMID: 33575317 PMCID: PMC7857919 DOI: 10.1155/2021/2906164] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 12/28/2020] [Accepted: 01/15/2021] [Indexed: 12/03/2022] Open
Abstract
Objective The follicular fluid (FF) plays an essential role in the physiology of the follicle and the oocyte. Gonadotropin stimulation affects the FF steroid hormone and anti-Mullerian hormone (AMH) concentrations, which has been suggested to be the reason for lower oocyte competence in conventional gonadotropin stimulated in vitro fertilisation (cIVF) compared to natural cycle IVF (NC-IVF). To analyse the effect of gonadotropin stimulation on a broad spectrum of signalling proteins, we ran proteomic antibody arrays on FF of women undergoing both treatments NC-IVF and cIVF. Method Twenty women underwent one NC-IVF and one cIVF treatment cycle. Follicular fluids of the first aspirated follicle were compared between the two groups using a protein microarray which included antibodies against 224 proteins related to cell signalling and reference proteins. Each of the 40 albumin-stripped, matched-pair samples was labelled in the reverse-dye (Cy3/Cy5) procedure before undergoing array hybridisation. Signal analysis was performed using normalisation algorithms in dedicated software. Five proteins yielding a value of P < 0.05 in the array experiment (Cystatin A, Caspase-3, GAD65/67, ERK-1, and ERK-2) were then submitted to quantitative determination by ELISA in the same follicular fluids. Results Array analysis yielded only a small number of differentially expressed signalling markers by unadjusted P values. Adjustment as a consequence of multiple determinations resulted in the absence of any significant differential marker expression on the array. Five unadjusted differentially expressed proteins were quantified immunometrically with antibodies from different sources. Follicular fluid concentrations of Cystatin A and MAP kinase ERK-1 concentrations were significantly higher in the cIVF than in the NC-IVF follicles, while GAD-2 (GAD65/67) did not differ. The assays for Caspase-3 and MAP kinase ERK-2 did not have the required sensitivities. Conclusion In contrast to FF steroid hormones and AMH, FF concentrations of signalling proteins are not or only marginally altered by gonadotropin stimulation.

Abstract
RESEARCH QUESTION Is the endocrine milieu different in women with low serum anti-Müllerian hormone (AMH) concentration compared with women with high concentration? DESIGN Cohort study of 84 women (four groups) classified according to AMH concentration and age undergoing natural cycle IVF treatment. Concentrations of LH, oestradiol, testosterone, androstenedione and AMH were determined in follicular fluid (FF), associations analysed and clinical outcome parameters evaluated. RESULTS A positive correlation between serum and FF AMH concentrations was confirmed. Follicular fluid androstenedione concentration was positively correlated with serum AMH concentration (P < 0.0001, r2 = 0.197). The correlation between FF LH and FF testosterone concentration in all women was not significant (P = 0.050, r2 = 0.046); however, the correlation between FF androstenedione in women with high serum AMH concentration was significant (P = 0.032, r2 = 0.220). Follicular fluid testosterone and androstenedione were positively correlated with FF oestradiol overall and in some individual groups. The high serum AMH concentration group showed the highest FF AMH and androstenedione concentrations and lowest oestradiol-testosterone and oestradiol-androstenedione ratios. High FF AMH concentration was associated with a higher clinical pregnancy rate and high FF oestradiol concentration with a slightly better embryo quality. CONCLUSIONS Differences in the endocrine milieu in women with high serum AMH concentration seem to be caused by increased follicular LH concentration. In women with high serum AMH concentration, FF androstenedione is increased and ratios of oestradiol-testosterone and oestradiol-androstenedione are decreased, suggesting a disturbed endocrine milieu caused by reduced metabolization of FF androgens into oestrogens. In natural cycles, FF AMH concentrations are positively associated with higher clinical pregnancy rates and oestradiol concentrations with a higher embryo score.

Abstract
STUDY QUESTION What is the relationship between the anti-Müllerian hormone (AMH), gonadotropin and androgen concentrations within a single follicle and live birth after ICSI and a transfer of an embryo developed from the matched oocyte? SUMMARY ANSWER Among the analysed markers on the day of oocyte retrieval, AMH concentration in follicular fluid (FF) is a predictor of live birth after single embryo transfer (SET). WHAT IS KNOWN ALREADY High serum concentrations of AMH and low FSH concentrations have been associated with a high chance of pregnancy after ART. Whether there are differences in the hormonal milieu for individual follicles and whether this impacts the laboratory and clinical outcomes for the individual oocyte developing within that follicle are unknown. STUDY DESIGN, SIZE, DURATION This prospective cohort study included 322 individual FF samples from 199 infertile women scheduled for ICSI/SET over an 18-month period. Of these women, 76 provided a single FF sample, while 123 women contributed two FF samples taken from two different follicles. PARTICIPANTS/MATERIALS, SETTING, METHODS The first follicle aspirated in each ovary on the day of oocyte retrieval had the FF aspirated; the individual cumulus-oocyte complex (COC) was tracked, and the associated FF was stored at -80°C. FF AMH, FSH, LH, testosterone (T) and androstenedione (A2) levels were measured by mass spectrometry (androgens) and immunoassays. The laboratory and clinical outcomes for each individual oocyte were related to their unique follicle hormone concentrations. MAIN RESULTS AND THE ROLE OF CHANCE Of the 322 oocytes with paired FF samples, 70 (21.7%) oocytes did not fertilise. From the remaining 252 2PN embryos, 88 (34.9%) were transferred as single embryos on Day 3; of the remaining 164, 78 developed into blastocysts, and 18 single blastocyst transfers were performed. Thus, a total of 106 transferred embryos had matching FF samples. An analysis of these individual FF concentrations revealed that AMH concentrations were higher in follicles in which the oocyte developed into a top quality (TQ) blastocyst (6.33 ± 5.52 ng/ml) and whose transfer led to live birth (7.49 ± 5.03 ng/ml) than those in which there was a failure of fertilisation (3.34 ± 2.21 ng/ml). In contrast, follicular FSH concentrations were the lower for oocytes that resulted in a TQ blastocyst (5.36 ± 2.20 mIU/ml) and live birth (5.60 ± 1.41 mIU/ml) than for oocytes that failed to fertilise (9.06 ± 3.36 mIU/ml). FF AMH was the only studied marker that increased the chance of live birth (odds ratio: 1.93 [95% CI: 1.40-2.67], P < 0.001). The receiver operating characteristic analysis showed that FF AMH levels predicted live birth with a very high sensitivity (91.2%), specificity (91.7%) and an excellent AUC value of 0.954, whereas serum AMH level only had a fair (AUC = 0.711) significance as a predictor for live birth after ICSI/SET. The predictive capabilities of the interfollicular markers were not limited to the TQ embryos or blastocysts; they applied to all SET cycles. LIMITATIONS, REASONS FOR CAUTION Whether an altered intrafollicular hormonal environment reflects the developmental capacity of the oocyte or defines cannot be determined from this cross-sectional analysis. Inclusion of 21 subjects with polycystic ovary syndrome (PCOS) may have biased the findings due to a unique intrafollicular milieu associated with PCOS. WIDER IMPLICATIONS OF THE FINDINGS Our results suggest that highly competent human oocytes have an FF composition of AMH, FSH, T and A2 that is close to that in a natural cycle. Also, the relationships between intrafollicular AMH, gonadotropin and androgen levels in the same follicle support the hypothesis that FF AMH concentration may reflect granulosa cell proliferation during gonadotropin-stimulated follicle growth. Finally, the serum AMH concentration is markedly lower than the FF AMH concentration, with a moderate correlation between serum and FF AMH, implying ovarian follicle autonomy with regards to its secretory products.

Abstract
Basic research into a possible link between serum and follicular fluid androgen concentrations to detemine whether androgen supplementation in low responders affects follicular endocrine milieu is still lacking. Ninety-seven women (aged 28-43 years) undergoing one natural IVF cycle without any hormone stimulation were analysed. Serum and follicular fluid were collected at the time of follicle aspiration, and the concentrations of LH, total testosterone, oestradiol, dehydroepiandrosterone and anti-Mullerian hormone (AMH) were determined. Serum LH (P = 0.003) and AMH (P = 0.026) concentrations, and follicular fluid AMH (P = 0.015) decreased with increasing age. Within follicular fluid, total testosterone was correlated with oestradiol (P < 0.001) and AMH (P = 0.010); LH correlated with AMH (P = 0.005). Correlation analysis of serum and follicular fluid hormone concentrations revealed that LH, oestradiol and AMH correlated (P < 0.001), whereas testosterone did not. Testosterone serum concentrations did not correlate with other follicular fluid hormones, such as dehydroepiandrosterone, oestradiol and AMH, whereas serum LH correlated with follicular flulid AMH (P < 0.008). Follicular fluid hormone concentrations seem to be independent from serum testosterone. Therefore, it is questionable whether an increase in serum testosterone concentration by androgen supplementation could improve the follicular endocrine milieu.

Intrafollicular inflammatory cytokines but not steroid hormone concentrations are increased in naturally matured follicles of women with proven endometriosis. J Assist Reprod Genet 2017; 34:357-364.

Abstract
PURPOSE The aim of this study was to assess whether the intrafollicular cytokine profile in naturally developed follicles is different in women with endometriosis, possibly explaining the lower reproductive outcome in endometriosis patients. METHODS A matched case-control study was conducted at a university-based infertility and endometriosis centre. The study population included 17 patients with laparoscopically and histologically confirmed endometriosis (rAFS stages II-IV), each undergoing one natural cycle IVF (NC-IVF) treatment cycle between 2013 and 2015, and 17 age-matched NC-IVF women without diagnosed endometriosis (control group). Follicular fluid and serum was collected at the time of follicle aspiration. The concentrations of inflammatory cytokines (IL-1β, IL-6, IL-8, IL-15, IL-18, TNF-α) and hormones (testosterone, estradiol, AMH) were determined in follicular fluid and serum by single or multiplexed immunoassay and compared between both groups. RESULTS In the follicular fluid, IL-1β and IL-6 showed significantly (P < 0.001 and 0.01, respectively) higher median concentrations in the endometriosis group than in the control group and a tendency towards endometriosis severity (rAFS stage) dependence. The levels of the interleukins detectable in follicular fluid were significantly higher than those in the serum (P < 0.01). Follicular estradiol concentration was lower in severe endometriosis patients than in the control group (P = 0.036). Follicular fluid IL-1β and IL-6 levels were not correlated with estradiol in the same compartment in neither patient group. CONCLUSIONS In women with moderate and severe endometrioses, some intrafollicular inflammatory cytokines are upregulated and not correlated with intrafollicular hormone concentrations. This might be due to the inflammatory microenvironment in endometriosis women, affecting follicular function and thereby possibly contributing to the reproductive dysfunction in endometriosis.

Why more is less and less is more when it comes to ovarian stimulation. J Assist Reprod Genet 2015; 32:1713-9.

Abstract
PURPOSE The purpose of the present study is to describe the possible mechanisms which may explain the apparent paradox of "less is more." Mild ovarian stimulation for in vitro fertilization (IVF) minimizes ovarian hyperstimulation syndrome (OHSS) and multiple gestations without compromising the pregnancy rate (PR). METHODS The pertinent English literature (PubMed) addressing mild stimulation for IVF/assisted reproductive technology (ART) and publications addressing "mild" or "soft" controlled ovarian stimulation (COS) vs conventional COS for IVF, OHSS, natural cycle IVF, and IVF outcome in association with COS was searched. RESULTS Four possible mechanisms can be put forward to explain the apparent paradox of "less is more." (1) In the natural or mild stimulation cycles, the healthiest follicles are selected by the principle of "quality for quantity"; (2) high estradiol (E2) in the late follicular phase significantly correlated with higher rates of small for gestational age (SGA) and low-birth-weight (LBW) neonates; (3) anti-Mullerian hormone (AMH), LH, testosterone, and E(2) are significantly higher in natural cycle (NC)-IVF than in stimulated IVF follicles, suggesting an alteration of the follicular metabolism in stimulated cycles; and (4) supraphysiological E(2) may increase the growth hormone-binding protein (GH-BP) bio-neutralizing GH and diminishing the resultant insulin-like growth factor (IGF) levels, necessary for optimal synergism with follicle-stimulating hormone (FSH). CONCLUSIONS It is suggested to aim at the retrieval of around eight to ten eggs. Mild stimulation should be the common practice for IVF. In cases where more than ten ova are retrieved or high E(2) levels are reached, either intentionally or unintentionally, "freeze-all policy" should be considered and embryo transfer (ET) done in a subsequent natural cycle.

Abstract
OBJECTIVE The aim of this study was to investigate the relationship of cathepsin B, relaxin and anti-Mullerian hormone (AMH) in follicular fluid (FF) with pregnancy rates in infertility patients. STUDY DESIGN Seventy-nine infertile couples who underwent ICSI were included in the study. The FF levels of cathepsin B, relaxin and AMH were measured using ELISA kits. RESULTS The FF cathepsin B levels were statistically higher in pregnant patients compared with non-pregnant patients (0.20±0.13 versus 0.13±0.03; P<0.001). There were statistically significant differences in the total number of oocytes (10.00±6.85 versus 5.96±3.94); the mean number of M2 oocytes (8.65±5.63 versus 4.58±3.36) between the pregnant and non-pregnant patients (P<0.05). There were no significant correlations between pregnancy rates and relaxin and AMH (P>0.05). The area under the curve of cathepsin B for prediction of pregnancy was 0.662 (p=0.024, 95% Confidence Interval 0.528-0.797). CONCLUSIONS This study demonstrated that increased level of cathepsin B in FF significantly correlates with a better chance of clinical pregnancy. Further studies are needed to clarify the role of cathepsin B in the reproductive process of humans.

Abstract
Our aim is to investigate the follicular fluid concentrations of antimullerian hormone and its effect on assisted reproductive technology (ART) outcome in non-obese, non-hyperandrogenemic polycystic ovary syndrome patients. Subjects were categorized according to in vitro fertilization (IVF) indications: Group 1 PCOS (n:16), Group 2 male factor infertility (n:19) and Group 3 unexplained infertiliy patients (n:19). Follicular fluid antimullerian hormone levels (FF AMH) on the day of oocyte retrieval were analysed and ART outcome was studied. FF AMH levels in group 1, 2 and 3 were 35.70 ng/ml (median); 17.90 ng/ml (median); 17.90 ng/ml (median), respectively (p = 0.18). There were correlations between the FF AMH levels and follicle, oocyte, 2PN and embryo numbers in pathophysiology of polycystic ovary syndrome (PCOS) patients (p = 0.012; 0.024; 0.027; 0.013 respectively). There were no correlations between the FF AMHand ART outcome parameters in group 2 and 3. FF AMH levels were not different between the groups who were pregnant or not (p = 0.06). In conclusion there were no significant differences in terms of FF AMH levels in the three groups. FF AMH levels can predict the recovery of oocytes but not oocyte quality, embryo quality or pregnancy in non-obese non-hyperandrogenemic PCOS patient.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common metabolic dysfunction and heterogeneous endocrine disorder in women of reproductive age. Although patients with PCOS are typically characterized by increased numbers of oocytes retrieved during IVF, they are often of poor quality, leading to lower fertilization, cleavage and implantation rates, and a higher miscarriage rate. METHODS For this review, we searched the database MEDLINE (1950 to January 2010) and Google for all full texts and/or abstract articles published in English with content related to oocyte maturation and embryo developmental competence. RESULTS The search showed that alteration of many factors may directly or indirectly impair the competence of maturating oocytes through endocrine and local paracrine/autocrine actions, resulting in a lower pregnancy rate in patients with PCOS. The extra-ovarian factors identified included gonadotrophins, hyperandrogenemia and hyperinsulinemia, although intra-ovarian factors included members of the epidermal, fibroblast, insulin-like and neurotrophin families of growth factors, as well as the cytokines. CONCLUSIONS Any abnormality in the extra- and/or intra-ovarian factors may negatively affect the granulosa cell-oocyte interaction, oocyte maturation and potential embryonic developmental competence, contributing to unsuccessful outcomes for patients with PCOS who are undergoing assisted reproduction.
