Negative associations of ideal family size achievement with hypertension, obesity and maternal age in women with and without polycystic ovary syndrome. Clin Endocrinol (Oxf) 2022; 97:217-226. [PMID: 35394665 DOI: 10.1111/cen.14736] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 03/07/2022] [Accepted: 03/08/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To investigate lifetime reproductive outcomes and the relationship of ideal family size (IFS) achievement with metabolic, psychiatric and reproductive history in women with and without polycystic ovary syndrome (PCOS). DESIGN Cross-sectional. PATIENT(S) A total of 9034 women with (n = 778) and without self-reported PCOS (n = 8256) born between 1973 and 1978 in the Australian Longitudinal Study on Women's Health. MEASUREMENTS Self-reported IFS achievement and total number of live births. RESULTS Women with and without PCOS aspired for similar IFS. Compared with women without PCOS, significantly less women with PCOS achieved their IFS (53.08% vs. 60.47%, p < 0.001). Higher proportion of women with PCOS did not achieve a live birth (37.15% vs. 31.64%, p = 0.002) and their median total number of live births was also lower (1 vs. 2, p < 0.001) than women without PCOS. After controlling for sociodemographic factors, negative associations were observed between IFS achievement and PCOS status, various metabolic, psychiatric and reproductive history. However, only hypertension (adjusted odds ratio [OR]: 0.82, 95% confidence interval [CI]: 0.67-1.00), obesity (adjusted OR: 0.79, 95% CI: 0.69-0.90), history of in vitro fertilisation use (IVF) (adjusted OR: 0.49, 95% CI: 0.38-0.63) and maternal age at first childbirth (adjusted OR: 0.92, 95% CI: 0.91-0.93) remained inversely associated with achievement of IFS in further multivariable regression models. CONCLUSION Metabolic conditions and reproductive history of maternal age at first childbirth and history of IVF use, but not psychological conditions, were associated with reduced odds of achieving IFS. Early family planning/initiation and optimisation of metabolic health may help to improve reproductive outcomes.

Abstract
OBJECTIVE The aim of this study was to assess whether luteinising hormone (LH) surge characteristics influenced the likelihood of conceiving naturally. METHODS This was a single-cycle, home-based, observational, case-controlled study. Volunteers collected daily urine samples for one menstrual cycle. LH was measured and the basal levels, surge day, peak day, peak concentration and magnitude of LH surges were examined. Predictive models using sociodemographic data, LH surge characteristics, and sociodemographic data combined with LH profile properties, were evaluated. RESULTS The surge profile did not differ between cycles with early or late ovulation and was not affected by age or body mass index (BMI). The mean LH surge day was day 16 for both groups. Mean LH surge and concentrations did not differ between groups (surge concentration 54.8 IU/l vs. 58.2 IU/l and peak concentration 82.0 IU/l vs. 81.6 IU/l for pregnant vs. non-pregnant volunteers, respectively). Non-pregnant volunteers were more likely, however, to have a raised or a reduced basal LH on day 6 or have an atypical LH profile. Sociodemographic characteristics were significant predictors of pregnancy, and sociodemographic variable-based models had the greatest predictive ability for conception, providing up to 65% predictive accuracy. CONCLUSIONS Sociodemographic variables can be used to predict the likelihood of a woman conceiving naturally. Provided an LH surge is present, its profile does not relate to the likelihood of spontaneous pregnancy. The conception rate was significantly lower, however, in women with elevated or reduced basal levels of LH, suggesting that follicular maturation needs an optimal basal level of LH in natural conception cycles.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is one of the most common (15-20%) endocrine disorders in women of childbearing age. Although it is a major cause of infertility, its etiology remains unknown and its treatment difficult. AIM To evaluate the incidence, treatment and outcome of patients with PCOS. DESIGN Retrospective analysis. MATERIALS AND METHODS PCOS patients (914 of the 1057) attending the outpatient department (OPD) from June 2003 to February 2008 were evaluated for this study. Of the 914 patients investigated, 814 came for treatment and these patients were studied for hormonal disturbances and their response to various modalities of treatment. RESULTS Of the 2270 infertility patients, 46.50% (1057) had PCOS, out of these, 86.47% (914) were investigated and 77% (814) came for treatment. Our overall pregnancy rate was 48.40% (394/814). The pregnancy rate per cycle with timed intercourse (TI) was 44.77% (47/105), 17.09% (286/1673) with intrauterine insemination (IUI), 29.82% (51/171) with in vitro fertilization (IVF) and 22.22% (10/45) with frozen embryo transfer (FET). The maximum number of pregnancies (85.29%, 284/333) were achieved in the first three treatment cycles. The abortion rate was 19.01% (73/384) and the incidence of ectopic pregnancy was 5.47% (21/384). Complications seen were in the form of ovarian hyperstimulation (OHSS), retention cyst on day two and multiple pregnancies in 11.71% (228/1946) of the total treatment cycles. CONCLUSION Most PCOS symptoms could be adequately controlled or eliminated with proper diagnosis and treatment. Thus, ovulation induction (OI) protocols and treatment modalities must be balanced for optimal results.

Abstract
Polycystic ovaries syndrome (PCOS) is one of the most common female hormonal disorders. Its multiple components--reproductive, metabolic, neoplasic and cardiovascular--have a major impact on the public health. Androgen excess and resistance to insulin, probably from genetic origin, are responsible for most of the clinical symptomatology. Resistance to insulin seems to be accompanied by a greater risk of glucose intolerance, type 2 diabetes, lipidic anomalies and can involve the development of cardiovascular diseases. In addition, sleep apnea syndrome is more progressively described in PCOS. Infertility, menses disorders and hirsutism often push these patients to consult their physician. A better understanding of the physiopathological mechanisms led to the emergence of new therapeutic options increasing the sensitivity to insulin. Besides the pregnancy wishes, cares aim to attenuate the marks of the hyper-androgenism (hormonal treatment and cosmetic) and to correct cardiovascular, respiratory and gynaecological risk factors. In case of infertility by anovulation, cares must be performed by trained experts to minimize the risk of ovarian hyper-stimulation syndrome and multiple pregnancies. A gradation from loose weight to clomiphene citrate ovulation induction, ovarian drilling, low dose gonadotropin, in vitro fertilisation, or in vitro maturation of oocytes should bring back good reproduction potential.

Abstract
The role of LH in the natural menstrual cycle is not disputed. However, there are a variety of opinions regarding the potential role of exogenous LH in ovulation induction and whether it is actually needed. Recent years have seen renewed interest in this issue for several reasons. First, ovulation-inducing drugs are increasingly being administered to normally ovulating women. Second, recombinant human FSH products completely devoid of LH activity are now available. Third, gonadotrophin-releasing hormone (GnRH) analogues (agonists and antagonists) prevent the untimely LH surge but also suppress endogenous LH activity during the follicular phase. This review analyses whether or not all patients need LH for follicular growth stimulation and new opportunities for improved treatment as a result of the availability of recombinant human LH both in patients with ovulatory disorders (World Health Organization (WHO) groups I and II anovulatory patients) and those undergoing multiple follicular development for assisted reproduction.

Abstract
Complications of pregnancy associated with maternal PCOS include increased prevalence of early pregnancy loss (EPL), gestational diabetes (GDM), pregnancy-induced hypertensive disorders (PET/PIH), and the birth of small-for-gestational-age (SGA) babies. Increased risk of EPL has been attributed to obesity, hyperinsulinaemia, elevated luteinizing hormone concentrations, and endometrial dysfunction. Avoiding obesity before pregnancy and treatment with metformin are therapeutic options, also for the increased prevalence of GDM. Administration of metformin throughout pregnancy is a contentious issue. Screening pregnant women with PCOS for GDM and PET/PIH-especially if they are obese-is recommended, although data for a firm association between PCOS and PET/PIH is weak. Impaired insulin-mediated growth and fetal programming are possible explanations for a higher prevalence of SGA infants in mothers with PCOS. Only prospective studies employing a large cohort of women with well-defined PCOS compared with a control group matched for BMI and parity can solve the remaining questions.

Abstract
Anovulation, a common cause of female infertility, is a highly curable condition. Presented here is a simple treatment-orientated diagnostic scheme. Anovulatory women with low endogenous oestradiol and follicle stimulating hormone (FSH) are treated with either pulsatile gonadotrophin releasing hormone (GnRH) or gonadotropins, and women with eu-oestrogenic anovulation (mostly with polycystic ovarian syndrome; PCOS) have first-line treatment with clomiphene citrate (CC), possibly with metformin. If CC fails, FSH is administered using a chronic low-dose protocol with small incremental dose rises. A comparison of urinary with recombinant and pure FSH with luteinising hormone (LH) containing gonadotropins is made. Recombinant products are purer and more convenient for use but are expensive. LH content has little impact except in hypogonadotropic hypogonadism or severe pituitary suppression with GnRH analogues. Aromatase inhibitors, recombinant LH and long-acting FSH may find a future place in the armamentarium.

Abstract
Three experiments were undertaken to investigate the effect of a pre-mating ram exposure during progestagen synchronisation treatment on time of breeding, ovulation rate, embryo quality and fertility and any interaction with time of ram introduction for breeding post sponge withdrawal. Crossbred ewes in experiment 1a (n = 348), 1b (mule; n = 133) and 2 (n = 58) underwent a 12-14 days synchronisation protocol. Three days prior to sponge withdrawal ewes were divided into Control (ewes in continued isolation from rams) or +Ram (ram-exposed) groups. Rams were introduced to +Ram ewes and remained with ewes until sponge withdrawal. Ewes in experiments 1a and 2 received eCG at sponge withdrawal and were reintroduced to rams at either 36 or 48 h post sponge removal (PSR). In experiment 1b, ewes did not receive eCG and were reintroduced to rams at 24 h PSR. In experiments 1a and 1b time of breeding, date of lambing and litter size were recorded. In experiment 2, ewes were slaughtered 5 days post breeding, reproductive tracts flushed and corpora lutea, ova and embryos assessed. Fewer +Ram ewes were mated by 96 h PSR (P < 0.001) than Control ewes in experiment 1a but not when rams were introduced earlier in experiment 1b. In experiment 1a, ram introduction at 36 h PSR improved conception to first service compared to introduction at 48 h PSR (P < 0.01) in both +Ram and Control groups. In experiments 1a and 1b, +Ram ewes had reduced litter size caused by more single births (1a; P < 0.001, 1b; P < 0.01). In experiment 2, +Ram ewes had fewer corpora lutea than Control ewes (P < 0.001) but embryo quality was similar. However, more good embryos were produced when rams were introduced for breeding at 36 h compared to 48 h PSR (P < 0.001). We conclude that a pre-mating ram exposure during the synchronisation treatment reduced the number of ewes mated at and conceiving to the first service. This was partially overcome by introducing rams for breeding earlier (24 or 36 h compared to 48 h PSR) but the most dramatic decrease in fertility was due to a reduction in ovulation rate in the ram-exposed ewes.

Abstract
Anovulatory infertility is a prevalent presenting feature of polycystic ovary syndrome (PCOS). Restoration of ovulation might be achieved by ovarian stimulation or by reducing insulin and LH concentrations. Clomiphene citrate is the first-line ovulation-inducing agent, usually followed by direct stimulation with follicle stimulating hormone (FSH), if unsuccessful. The prevalent complications of ovarian hyperstimulation syndrome and multiple pregnancies can largely be avoided by administering FSH in a low dose and individualized regimen. Hyperinsulinaemia can be corrected by weight loss or insulin-sensitizing agents, such as metformin, which alone or in combination with other agents are capable of restoring ovulation. Advice about weight loss is critical in modern management of PCOS and infertility. Laparoscopic ovarian drilling produces similar results to FSH stimulation, and in vitro fertilization/embryo transfer (IVF/ET)-if all else fails-produces excellent results. The possible use of aromatase inhibitors, novel insulin sensitizers and in vitro maturation of oocytes is still being evaluated. The plethora of treatment options available today ensures that the great majority of women who are subfertile due to PCOS can be treated successfully.

Abstract
The present study tests the hypothesis that specific endocrine, metabolic, and anthropometric features distinguish obese women with polycystic ovary syndrome (PCOS) who resume ovulation in response to calorie restriction and weight loss from those who do not. Fifteen obese (body mass index 39 +/- 7 kg/m(2)) hyperandrogenemic oligoovulatory patients undertook a very low calorie diet (VLCD), wherein each lost > or =10% of body weight over a mean of 6.25 mo. Body fat distribution was quantitated by magnetic resonance imaging. Hormones were measured in the morning at baseline, after 1 wk of VLCD, and after 10% weight loss. To monitor LH release, blood was sampled for 24 h at 10-min intervals before intervention and after 7 days of VLCD. Responders were defined a priori as individuals exhibiting two or more ovulatory cycles in the course of intervention, as corroborated by serum progesterone concentrations > or =18 nmol/l followed by vaginal bleeding. At baseline, responders had a higher sex hormone-binding globulin (SHBG) concentration but were otherwise indistinguishable from nonresponders. Body weight, the size of body fat depots, and plasma insulin levels declined to a similar extent in responders and nonresponders. Also, SHBG increased, and the free testosterone index decreased comparably. However, responders exhibited a significant decline of circulating estradiol concentrations (from 191 +/- 82 to 158 +/- 77 pmol/l, means +/- SD, P = 0.037) and a concurrent increase in LH secretion (from 104 +/- 42 to 140 +/- 5 U.l(-1).day(-1), P = 0.006) in response to 7 days of VLCD, whereas neither parameter changed significantly in nonresponders. We infer that evidence of retention of estradiol-dependent negative feedback on LH secretion may forecast follicle maturation and ovulation in obese patients with PCOS under dietary restriction.

Abstract
This single centre randomized controlled trial was undertaken to compare the efficacy and safety of clomiphene citrate and low-dose recombinant FSH as first line pharmacological therapy for anovulatory infertility associated with polycystic ovary syndrome (PCOS). Seventy-six infertile patients with PCOS were randomized to receive clomiphene citrate (50-150 mg/day for 5 days) (clomiphene citrate group, n = 38) or recombinant human FSH (FSH group, n = 38) in a chronic, low-dose, step-up protocol (daily starting dose 75 IU) for up to three consecutive cycles. Ovarian response was monitored by transvaginal ultrasonography and human chorionic gonadotrophin (HCG) was given to trigger ovulation in all cycles with appropriate follicular development. The primary outcome measure was cumulative pregnancy after undergoing up to three treatment cycles. Secondary outcomes were cycle cancellation rate, ovulation rate per cycle, cumulative ovulation rate, pregnancy rate per cycle, incidence of OHSS, cumulative live birth rate, and multiple birth rate. One hundred and four clomiphene citrate cycles and 91 FSH cycles were evaluable. The relative risk and its 95% confidence interval were 1.17 (0.97-1.46) for HCG cycles with ovulation, 1.78 (0.92-3.54) for the pregnancy rate per woman, and 1.83 (0.79-4.40) for live births per woman in favour of FSH. The cumulative pregnancy rate after three treatment cycles was 43% with FSH and 24% with clomiphene citrate (P = 0.06). By logistic regression analysis, the factors predicting ovulation included female age, serum androstenedione and use of FSH. Predictors of pregnancy were duration of infertility and use of FSH. This randomized controlled trial suggests that low-dose recombinant FSH may be an effective alternative to clomiphene citrate in first-line treatment for anovulatory PCOS patients. Thus, further studies, possibly multi-centre, in order to avoid problems with patient recruitment, are warranted to confirm these results.

Abstract
The aim of this prospective, randomized trial was to compare the clinical results and the cost-effectiveness of urinary FSH (uFSH) and recombinant FSH (rFSH) in ovarian stimulation for intrauterine insemination (IUI) cycles in polycystic ovary syndrome (PCOS) patients. One-hundred and seventy PCOS infertile patients undergoing IUI were enrolled, and protocols of ovarian stimulation with uFSH or rFSH were randomly assigned. The total number of cycles performed was 379 (182 and 197, respectively). The main outcome measures were the number of mature follicles, the days of stimulation, the number of ampoules and IU used per cycle, the biochemical/clinical pregnancy rates, the number of multiple pregnancies and the cost-effectiveness. No statistically significant differences were found in the follicular development, length of stimulation, pregnancy rates, delivery rates and multiple pregnancies between the two groups. In the uFSH group, the cost per cycle remained significantly lower (218.51 +/- 88.69 versus 312.22 +/- 118.12; P < 0.0001), even though a significantly higher number of IU of gonadotrophins were used (809.3 +/- 271.9 versus 589.1 +/- 244.7; P < 0.0001). The cost-effectiveness (i. e. within a group, the total cost of all cycles divided by no. of clinical pregnancies) was 1729.08 in the uFSH group and 3075.37 in the rFSH group. In conclusion, uFSH and rFSH demonstrated the same effectiveness in ovarian stimulation in IUI cycles in PCOS patients. The urinary preparation is more cost-effective due to the difference of its cost per IU.

Polycystic ovary syndrome [PCOS] is the commonest cause of anovulatory infertility. Treatment modes available are numerous mainly relying on ovarian stimulation with FSH, a reduction in insulin concentrations and a decrease in LH levels as the basis of the therapeutic principles. Clomiphene citrate is still the first line treatment and if unsuccessful is usually followed by direct FSH stimulation. This should be given in a low dose protocol, essential to avoid the otherwise prevalent complications of ovarian hyperstimulation syndrome and multiple pregnancies. The addition of a GnRH agonists, while very useful during IVF/ET, adds little to ovulation induction success whereas the position of GnRH antagonists is not yet clear. Hyperinsulinemia is the commonest contributor to the state of anovulation and its reduction, by weight loss or insulin sensitizing agents such as metformin, will alone often restore ovulation or will improve results when used in combination with other agents. Laparoscopic ovarian drilling is proving equally as successful as FSH for the induction of ovulation, particularly in thin patients with high LH concentrations. Aromatase inhibitors are presently being examined and may replace clomiphene in the future. When all else has failed, IVF/ET produces excellent results. In conclusion, there are very few women suffering from anovulatory infertility associated with PCOS who cannot be successfully treated today.

Abstract
Elevated LH concentrations are frequently encountered in patients with polycystic ovary syndrome (PCOS) and increased LH (either endogenous or superimposed through the use of HMG) may have detrimental effects on reproductive function. In spite of this, FSH-only products and HMG have been used indiscriminately for ovulation induction - on the basis that the administration of HMG to patients with PCOS, who are not receiving GnRH agonists, does not result in significant increases in serum LH concentrations as judged by daily single blood samples. However, both endogenous and exogenous LH have a relatively short terminal half-life and studies have reported normal serum LH, but abnormal urinary LH and emphasized that early morning urinary measurements are more informative than those in serum because they reflect nocturnal LH secretion. Therefore, the present study was undertaken to perform a pharmacokinetic and endocrine comparison of recombinant human FSH and HMG in PCOS patients including LH measurements in the urine. Five PCOS patients receiving s.c. recombinant human FSH (rhFSH) and five PCOS patients receiving i.m. HMG for ovulation induction according to a chronic low-dose step-up regimen underwent blood and urine sampling at the following study points: Point 0 was the day of HCG injection; Points 1 to 5 corresponded to days HCG -1 to -2; -3 to -4; -5 to -6; -7 to -8; and -9 to -10; respectively. Serum hormone measurements included oestradiol, FSH, LH, progesterone, inhibin A, androstenedione, testosterone, and free testosterone index. FSH and LH were also measured daily in 8-h urine samples reflecting overnight renal urine secretion. Hormone concentrations calculated as the area under the curve showed that both FSH and LH concentrations in urine were significantly higher in HMG group than in group rhFSH. It is concluded that both LH and FSH concentrations significantly accumulate in the urine of PCOS patients receiving HMG for ovulation induction in a chronic low-dose protocol as compared with rhFSH treatment.

Abstract
The role of luteinizing hormone in the natural menstrual cycle is not disputed. There are, however, a variety of opinions regarding the potential role of exogenous luteinizing hormone in ovulation induction and whether it is actually needed. The recent introduction into clinical practice of recombinant gonadotropins has been paralleled by recent advances in the knowledge of the endocrine and paracrine mechanisms that regulate human folliculogenesis. On this basis, this review analyses whether or not all patients need luteinizing hormone for follicular growth stimulation. In addition, new opportunities for improved treatment are considered as a result of the availability of recombinant human luteinizing hormone both in patients with ovulatory disorders and those undergoing multiple follicular development for assisted reproduction.

Abstract
OBJECTIVES The present study was designed to determine whether clinical and endocrine characteristics assessed on initial screening of normogonadotropic oligo/amenorrhoeic infertile patients could predict ovulation and then conception and successful live birth or miscarriage. STUDY DESIGN Retrospective cohort study SETTING Outpatient clinic. POPULATION Eighty-two consecutive women receiving clomiphene citrate (CC) therapy from 1993 to 1998. RESULTS A cumulative conception rate of 67% was reached after six or more CC-induced cycles. Patients with failure of ovulation after a full course of CC had more severe oligomenorrhoea (p < 0.001) and greater BMI (p < 0.05) at initial screening. There was no relationship with levels of LH or androgens. In contrast, among women who ovulated in response to CC, conception was associated with less frequent periods, and higher basal levels of LH, free testosterone and androstenedione. Conceptions with subsequent miscarriage were associated with intermediate levels of LH and numbers of spontaneous periods between non-conception and live births. CONCLUSIONS These observations are consistent with the hypothesis that failure of ovulation after CC is related to different factors (overweight and severe oligomenorrhoea) from those that predispose to non-conception (low basal LH and androgen levels and mild oligomenorrhoea).

Abstract
We hypothesized that short-term calorie restriction would blunt luteinizing hormone (LH) hypersecretion in obese women with polycystic ovary syndrome (PCOS) and thereby ameliorate the anovulatory endocrine milieu. To test this hypothesis, 15 obese patients with PCOS and nine age- and body mass index-matched healthy women underwent 24-h blood sampling to quantitate plasma LH, leptin, and insulin levels. PCOS subjects were prescribed a very low caloric liquid diet (4.2 MJ/day) for 7 days and were then resampled. Basal and pulsatile LH secretion was threefold higher in PCOS subjects, but plasma insulin and leptin levels were not different in the calorie-replete state. Contrary to expectation, calorie restriction enhanced basal and pulsatile LH secretion even further. As expected, plasma glucose, insulin, and leptin concentrations decreased by 18, 75, and 50%, respectively. Serum total testosterone concentration fell by 23%, whereas serum estrone, estradiol, sex hormone-binding globulin (SHBG), and androstenedione concentrations remained unchanged. Enhanced LH secretion in the presence of normal metabolic and hormonal adaptations to calorie restriction points to anomalous feedback control of pituitary LH release in PCOS.

Abstract
OBJECTIVE To investigate the relationship between Day 8 serum luteinizing hormone (LH) and testosterone (T) concentrations, and body mass index (BMI) with pregnancy outcome in women with recurrent miscarriage. DESIGN Prospective observational study. SETTING National recurrent miscarriage clinic. PATIENT(S) Three hundred forty-four women (median age 32 years; range 18-44) with a history of recurrent first trimester miscarriage (median 4; 3-14; <12 weeks gestation) who conceived spontaneously and who received no pharmacological treatment during pregnancy were studied. All women were antiphospholipid antibody negative and had a normal peripheral karyotype as did their partners. INTERVENTION(S) Outcome of untreated pregnancies. MAIN OUTCOME MEASURE(S) Day 8 serum LH and T concentrations and BMI were correlated with pregnancy outcome. RESULT(S) One hundred and ninety-two (55.8%) women had a live birth and 152 (44.2%) women miscarried. Polycystic ovarian morphology was diagnosed in 174 women (50.6%). There was no significant relationship between follicular phase LH concentrations and pregnancy outcome. Pregnancy outcome was similar in women with normal and high serum T concentrations. BMI value was not significantly different between women who had a live birth and those who miscarried. CONCLUSION(S) The analysis of this large cohort of women with recurrent miscarriage demonstrates that prepregnancy Day 8 serum LH and T concentrations, and BMI do not have a statistically significant relationship with pregnancy outcome.
