A multi-centre international study of salivary hormone oestradiol and progesterone measurements in ART monitoring.

RESEARCH QUESTION: Ovarian stimulation during IVF cycles involves close monitoring of oestradiol, progesterone and ultrasound measurements of follicle growth. In contrast to blood draws, sampling saliva is less invasive. Here, a blind validation is presented of a novel saliva-based oestradiol and progesterone assay carried out in samples collected in independent IVF clinics. DESIGN: Concurrent serum and saliva samples were collected from 324 patients at six large independent IVF laboratories. Saliva samples were frozen and run blinded. A further 18 patients had samples collected more frequently around the time of HCG trigger. Saliva samples were analysed using an immunoassay developed with Salimetrics LLC. RESULTS: In total, 652 pairs of saliva and serum oestradiol were evaluated, with correlation coefficients ranging from 0.68 to 0.91. In the European clinics, a further 237 of saliva and serum progesterone samples were evaluated; however, the correlations were generally poorer, ranging from -0.02 to 0.22. In the patients collected more frequently, five out of 18 patients (27.8%) showed an immediate decrease in oestradiol after trigger. When progesterone samples were assessed after trigger, eight out of 18 (44.4%) showed a continued rise. CONCLUSIONS: Salivary oestradiol hormone testing correlates well to serum-based assessment, whereas progesterone values, around the time of trigger, are not consistent from patient to patient.

Salivary estradiol as a surrogate marker for serum estradiol in assisted reproduction treatment.

INTRODUCTION: Controlled ovarian hyper-stimulation for in vitro fertilization or intra cytoplasmatic sperm injection necessitates close monitoring using ultrasound and estradiol measurements. Monitoring is also important to prevent or limit the severity of ovarian hyper stimulation syndrome, an iatrogenic and potentially life-threatening complication. Self-operated endovaginal telemonitoring has been shown to offer an attractive and less costly alternative to classic consultation and saliva estradiol measurements could be a stress-free and practical alternative to serial blood determinations. Objectives were to evaluate whether saliva can be a surrogate marker for serum estradiol and its potential applicability in assisted reproduction treatment monitoring. MATERIAL AND METHODS: Serial blood and saliva samples were collected from 31 patients undergoing ovarian hyper-stimulation. All patients were followed-up using in-house serial vaginal sonograms and immunoassay serum estradiol measurements. Afterwards estradiol was determined in saliva and serum by LC-MS/MS. For a subset equilibrium dialysis and measurement of free serum estradiol was performed. RESULTS: About 1% of estradiol is present in serum in its free, unbound, form. Salivary estradiol correlates well to both serum free estradiol and serum total estradiol (r=0.80). The concentration of salivary estradiol corresponds to the unbound concentration in serum. The dynamics observed in serum monitoring during treatment are closely mimicked in saliva. ROC analysis on the current limited dataset suggested a saliva cut-off of 22pg/mL (81pmol/L) could help predict risk for OHSS. CONCLUSIONS: Salivary E2 can be considered a surrogate marker for free serum estradiol and total serum estradiol in assisted reproduction treatment. Additionally there might be a role as a prediction marker for OHSS although this finding has to be validated in larger datasets.

Gonadotropin Therapy versus Laparoscopic Ovarian Drilling in Clomiphene Citrate-Resistant Polycystic Ovary Syndrome Patients: A Retrospective Cost-Effectiveness Analysis.

BACKGROUND: Gonadotropin therapy and laparoscopic ovarian drilling (LOD) are treatment options for ovulation induction (OI) in clomiphene citrate (CC)-resistant polycystic ovary syndrome (PCOS) patients. The current evidence of the cost-effectiveness of both treatments is scarce, conflicting and performed from different health-economic perspectives. METHODS: A retrospective health-economic evaluation was performed from a societal perspective in which human menopausal gonadotropin (hMG) therapy (n = 43) was compared with LOD (n = 35), followed by OI with CC and/or hMG if spontaneous ovulation did not occur within 2 months. Data were collected until the patients were pregnant, with a time limit of 6 months after the onset of treatment. Outcomes were expressed as ongoing pregnancy rate and number of live-born children. RESULTS: The ongoing pregnancy rate was 21/35 (60%) after LOD and 30/43 (69.8%) after hMG treatment (relative risk 0.85, 95% CI 0.61-1.19). The societal cost per patient, up to an ongoing pregnancy, was significantly higher after LOD versus hMG treatment (adjusted mean difference EUR 1,073, 95% CI 180-1,967). CONCLUSION: This economic evaluation based on real-life data shows that the societal cost up to an ongoing pregnancy is less after hMG treatment when compared with LOD surgery in CC-resistant PCOS patients.

Mutation-free baby born from a mitochondrial encephalopathy, lactic acidosis and stroke-like syndrome carrier after blastocyst trophectoderm preimplantation genetic diagnosis.

To investigate the applicability of preimplantation genetic diagnosis (PGD), we used trophectoderm (TE) biopsy to determine the mutation load in a 35-year-old female with mitochondrial encephalopathy, lactic acidosis and stroke-like syndrome (MELAS). Transfer of a mutation-free blastocyst gave birth to a healthy boy with undetectable mutation in any of the analyzed tissues. We found strong correlation among TE cells (r=0.90) within blastocysts and also between cytoplasmic fragments and TE (r=0.95). This is the first case of mutation-free baby born from a MELAS patient after TE biopsy and supports the applicability of blastocyst PGD for patients with mtDNA disorders to establish healthy offspring.

Adding serum estradiol measurements to ultrasound monitoring does not change the yield of mature oocytes in IVF/ICSI.

In a non-randomized, comparative prospective study (416 patients) we compared the outcome of IVF/ICSI in two parallel control groups: one in which patients were followed up using combined monitoring (ultrasound plus serum estradiol monitoring, the UHM group) and one in which only ultrasound monitoring was used (the UM group). This study has taken the number of mature oocytes at the moment of egg retrieval as its primary end variable. After adjustment for age, gravidity, antagonist protocol, AMH and infertility diagnosis, the average difference in number of mature oocytes between the UHM group and the UM group was -0.4 (95% CI: -1.7 to 1.0), which met our definition of clinical equivalence (95% CI for the adjusted mean difference between -2 and 2). Larger studies are still needed to evaluate the differences in the live birth rates per cycle and to further confirm that blood sampling definitively has no added value in monitoring ovarian stimulation for IVF/ICSI.

Delaying the oocyte maturation trigger by one day leads to a higher metaphase II oocyte yield in IVF/ICSI: a randomised controlled trial.

BACKGROUND: The negative impact of rising progesterone levels on pregnancy rates is well known, but data on mature oocyte yield are conflicting. We examined whether delaying the oocyte maturation trigger in IVF/ICSI affected the number of mature oocytes and investigated the potential influence of serum progesterone levels in this process. METHODS: Between January 31, 2011, and December 31, 2011, 262 consecutive patients were monitored using ultrasound plus hormonal evaluation. Those with > =3 follicles with a mean diameter of > =18 mm were divided into 2 groups depending on their serum progesterone levels. In cases with a progesterone level < = 1 ng/ml, which was observed in 59 patients, 30-50% of their total number of follicles (only counting those larger than 10 mm) were at least 18 mm in diameter. These patients were randomised into 2 groups: in one group, final oocyte maturation was triggered the same day; for the other, maturation was triggered 24 hours later. Seventy-two patients with progesterone levels > 1 ng/ml were randomised in the same manner, irrespective of the percentage of larger follicles (> = 18 mm). The number of metaphase II oocytes was our primary outcome variable. Because some patients were included more than once, correction for duplicate patients was performed. RESULTS: In the study arm with low progesterone (<= 1 ng/ml), the mean number of metaphase II oocytes (+/-SD) was 10.29 (+/-6.35) in the group with delayed administration of the oocyte maturation trigger versus 7.64 (+/-3.26) in the control group. After adjusting for age, the mean difference was 2.41 (95% CI: 0.22-4.61; p = 0.031). In the study arm with elevated progesterone (>1 ng/ml), the mean numbers of metaphase II oocytes (+/-SD) were 11.81 (+/-9.91) and 12.03 (+/-7.09) for the delayed and control groups, respectively. After adjusting for PCOS (polycystic ovary syndrome) and female pathology, the mean difference was -0.44 (95% CI: -3.65-2.78; p = 0.79). CONCLUSIONS: Delaying oocyte maturation in patients with low progesterone levels yields greater numbers of mature oocytes.

Relation of androgen receptor sensitivity and mood to sexual desire in hormonal contraception users.

BACKGROUND: Since very little research in this field is available, this study aims to assess the role of psychosexual, relationship, hormonal and genetic measures in the sexual desire of users of three hormonal contraceptive products [low-dose combined oral contraceptive (20 mcg ethinylestradiol/150 mcg desogestrel), progestin-only pill (75 mcg desogestrel) and vaginal ring (daily dose of 15 mcg ethinylestradiol/120 mcg etonogestrel)]. STUDY DESIGN: Fifty-five couples were randomized over three groups in which the women consecutively used each product during 3 months. Both partners repeatedly filled out questionnaires on solitary and dyadic sexual desire (desire to behave sexually by oneself or towards a partner). Total and free testosterone, sex hormone binding globulin and a genetic marker of androgen receptor sensitivity [cytosine-adenine-guanine (CAG) repeat length] were assessed on blood samples of the female partners. RESULTS: Sexual desire was higher in women with either short or long CAG repeats (solitary, p=.004; dyadic, p=.008). Desire levels were higher during vaginal ring use (solitary, p=.018; dyadic, p=.007). The woman's mood was found to impact her dyadic sexual desire (p<.001); this scale was also strongly associated with the male partner's dyadic sexual desire (p<.001). CONCLUSIONS: The current study found evidence for a role of androgen receptor sensitivity and mood in the sexual desire of hormonal contraceptive users.

Clinical and transvaginal sonographic evaluation of the prostate in transsexual women.

OBJECTIVES: To assess feasibility and diagnostic performance of prostate examination through transvaginal palpation and transvaginal ultrasound in transsexual women (TSW). METHODS: Fifty TSW who were at least 6 months' posttransition were recruited in a University Hospital. Speculum examination and digital vaginal examination were performed by a gynecologist. Transvaginal ultrasound of the prostate was performed by a radiologist. The information gathered included: ease of insertion of the speculum, vaginal length, palpability of the prostate, vaginal mobility and presence of scar tissue, ease of introduction of the ultrasound probe, ability to visualize prostate and seminal vesicles, echogenicity of the peripheral zone and the central gland, presence of calcifications and delineation of prostatic capsule, attitude toward gynecologic examinations, and anticipated and experienced painfulness of the different examinations. RESULTS: Speculum examination was possible in all but 1 patient and was easy in 78% of the patients. Median vaginal length was 7 cm. A regular digital vaginal examination was possible in 44% of the patients, the vagina was rather mobile and with limited scar tissue on average. In 48% of the patients, the prostate was palpable. In 94% of the patients, the prostate was visible on transvaginal ultrasound. Mean prostate volume was 14 mL, calcifications were present in 33%, and none had cysts. Capsule of the prostate was well delineated in 74% and seminal vesicles were visualized in 80%. All examinations were very well tolerated and nearly painless. CONCLUSIONS: Gynecologic examination and prostate assessment were acceptable to TSW. Transvaginal palpation of the prostate is of poor clinical value, yet transvaginal ultrasound allows for proper evaluation of the prostate status.

Long-term assessment of the physical, mental, and sexual health among transsexual women.

INTRODUCTION: Transsexualism is the most extreme form of gender identity disorder and most transsexuals eventually pursue sex reassignment surgery (SRS). In transsexual women, this comprises removal of the male reproductive organs, creation of a neovagina and clitoris, and often implantation of breast prostheses. Studies have shown good sexual satisfaction after transition. However, long-term follow-up data on physical, mental and sexual functioning are lacking. AIM: To gather information on physical, mental, and sexual well-being, health-promoting behavior and satisfaction with gender-related body features of transsexual women who had undergone SRS. METHODS: Fifty transsexual women who had undergone SRS >or=6 months earlier were recruited. MAIN OUTCOME MEASURES: Self-reported physical and mental health using the Dutch version of the Short-Form-36 (SF-36) Health Survey; sexual functioning using the Dutch version of the Female Sexual Function Index (FSFI). Satisfaction with gender-related bodily features as well as with perceived female appearance; importance of sex, relationship quality, necessity and advisability of gynecological exams, as well as health concerns and feelings of regret concerning transition were scored. RESULTS: Compared with reference populations, transsexual women scored good on physical and mental level (SF-36). Gender-related bodily features were shown to be of high value. Appreciation of their appearance as perceived by others, as well as their own satisfaction with their self-image as women obtained a good score (8 and 9, respectively). However, sexual functioning as assessed through FSFI was suboptimal when compared with biological women, especially the sublevels concerning arousal, lubrication, and pain. Superior scores concerning sexual function were obtained in those transsexual women who were in a relationship and in heterosexuals. CONCLUSIONS: Transsexual women function well on a physical, emotional, psychological and social level. With respect to sexuality, they suffer from specific difficulties, especially concerning arousal, lubrication, and pain.
