Abstract
RESEARCH QUESTION Can an optimal LH threshold algorithm accurately predict timing of ovulation for natural cycle-intrauterine insemination (NC-IUI)? DESIGN A retrospective cohort study (2018-2022) including 2467 natural cycles. Ovulation timing for these cycles was determined using a previously developed AI model. Two LH thresholds, low and high, were determined in the LH algorithm. Being below the low threshold meant that ovulation is likely to occur in ≥ 4 days, suggesting another daily blood test. Between the two thresholds meant that ovulation was likely in 2-3 days, suggesting IUI the next day. Above the high threshold meant that ovulation will likely occur tomorrow, suggesting performing IUI on the same day. RESULTS The optimal LH model with a high threshold of 40 mIU/ml and a low threshold of 11 mIU/ml succeeded in correctly predicting timing for IUI (day - 1, - 2 relative to ovulation) in 75.4% (95%CI 75.3-75.4). In 23.1% (95%CI 23.0-23.2), the algorithm predicted "error," suggesting performing insemination when in fact it would have been performed on a non-optimal day (0 or - 3). A previously described 3-hormone-based (LH, estradiol, progesterone) AI model performed significantly better in all parameters (93.6% success rate, 4.3 "error" rate). CONCLUSIONS An LH threshold model, representing common practice, evaluating all possible high and low LH threshold combinations, was successful in accurately scheduling timing for IUI in only 75% of cases. Integrating all three hormones as performed in the AI model may have an advantage in accurately predicting the optimal time for IUI, over the use of LH only.

Abstract
BACKGROUND Many factors influence fertility, one being the timing of intercourse. The 'fertile window' describes a stage in the cycle when conception can occur and is approximately five days before to several hours after ovulation. 'Timed intercourse' is the practice of prospectively identifying ovulation and, thus, the fertile window to increase the likelihood of conception. Methods of predicting ovulation include urinary hormone measurement (luteinising hormone (LH) and oestrogen), fertility awareness-based methods (FABM) (including tracking basal body temperatures, cervical mucus monitoring, calendar charting/tracking apps), and ultrasonography. However, there are potentially negative aspects associated with ovulation prediction, including stress, time consumption, and cost implications of purchasing ovulation kits and app subscriptions. This review considered the evidence from randomised controlled trials (RCTs) evaluating the use of timed intercourse (using ovulation prediction) on pregnancy outcomes. OBJECTIVES To evaluate the benefits and risks of ovulation prediction methods for timing intercourse on conception in couples trying to conceive. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility (CGF) Group Specialised Register, CENTRAL, MEDLINE, and Embase in January 2023. We also checked the reference lists of relevant studies and searched trial registries for any additional trials. SELECTION CRITERIA We included RCTs that compared methods of timed intercourse using ovulation prediction to other forms of ovulation prediction or intercourse without ovulation prediction in couples trying to conceive. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane to select and analyse studies in this review. The primary review outcomes were live birth and adverse events (such as depression and stress). Secondary outcomes were clinical pregnancy, pregnancy (clinical or positive urinary pregnancy test not yet confirmed by ultrasound), time to pregnancy, and quality of life. We assessed the overall quality of the evidence for the main comparisons using GRADE methods. MAIN RESULTS This review update included seven RCTs involving 2464 women or couples. Four of the five studies from the previous review were included in this update, and three new studies were added. We assessed the quality of the evidence as moderate to very low, the main limitations being imprecision, indirectness, and risk of bias. Urinary ovulation tests versus intercourse without ovulation prediction Compared to intercourse without ovulation prediction, urinary ovulation detection probably increases the chance of live birth in couples trying to conceive (risk ratio (RR) 1.36, 95% confidence interval (CI) 1.02 to 1.81, 1 RCT, n = 844, moderate-quality evidence). This suggests that if the chance of a live birth without urine ovulation prediction is 16%, the chance of a live birth with urine ovulation prediction is 16% to 28%. However, we are uncertain whether timed intercourse using urinary ovulation detection resulted in a difference in stress (mean difference (MD) 1.98, 95% CI -0.87 to 4.83, I² = 0%, P = 0.17, 1 RCT, n = 77, very low-quality evidence) or clinical pregnancy (RR 1.09, 95% CI 0.51 to 2.31, I² = 0%, 1 RCT, n = 148, low-quality evidence). Similar to the live birth result, timed intercourse using urinary ovulation detection probably increases the chances of clinical pregnancy or positive urine pregnancy test (RR 1.28, 95% CI 1.09 to 1.50, I² = 0, 4 RCTs, n = 2202, moderate-quality evidence). This suggests that if the chance of a clinical pregnancy or positive urine pregnancy test without ovulation prediction is assumed to be 18%, the chance following timed intercourse with urinary ovulation detection would be 20% to 28%. Evidence was insufficient to determine the effect of urine ovulation tests on time to pregnancy or quality of life. Fertility awareness-based methods (FABM) versus intercourse without ovulation prediction Due to insufficient evidence, we are uncertain whether timed intercourse using FABM resulted in a difference in live birth rate compared to intercourse without ovulation prediction (RR 0.95, 95% CI 0.76 to 1.20, I² = 0%, 2 RCTs, n = 157, low-quality evidence). We are also uncertain whether FABM affects stress (MD -1.10, 95% CI -3.88 to 1.68, 1 RCT, n = 183, very low-quality evidence). Similarly, we are uncertain of the effect of timed intercourse using FABM on anxiety (MD 0.5, 95% CI -0.52 to 1.52, P = 0.33, 1 RCT, n = 183, very low-quality evidence); depression (MD 0.4, 95% CI -0.28 to 1.08, P = 0.25, 1 RCT, n = 183, very low-quality evidence); or erectile dysfunction (MD 1.2, 95% CI -0.38 to 2.78, P = 0.14, 1 RCT, n = 183, very low-quality evidence). Evidence was insufficient to detect a benefit of timed intercourse using FABM on clinical pregnancy (RR 1.13, 95% CI 0.31 to 4.07, 1 RCT, n = 17, very low-quality evidence) or clinical or positive pregnancy test rates (RR 1.08, 95% CI 0.89 to 1.30, 3 RCTs, n = 262, very low-quality evidence). Finally, we are uncertain whether timed intercourse using FABM affects the time to pregnancy (hazard ratio 0.86, 95% CI 0.53 to 1.38, 1 RCT, n = 140, low-quality evidence) or quality of life. No studies assessed the use of timed intercourse with pelvic ultrasonography. AUTHORS' CONCLUSIONS The new evidence presented in this review update shows that timed intercourse using urine ovulation tests probably improves live birth and pregnancy rates (clinical or positive urine pregnancy tests but not yet confirmed by ultrasound) in women under 40, trying to conceive for less than 12 months, compared to intercourse without ovulation prediction. However, there are insufficient data to determine the effects of urine ovulation tests on adverse events, clinical pregnancy, time to pregnancy, and quality of life. Similarly, due to limited data, we are uncertain of the effect of FABM on pregnancy outcomes, adverse effects, and quality of life. Further research is therefore required to fully understand the safety and effectiveness of timed intercourse for couples trying to conceive. This research should include studies reporting clinically relevant outcomes such as live birth and adverse effects in fertile and infertile couples and utilise various methods to determine ovulation. Only with a comprehensive understanding of the risks and benefits of timed intercourse can recommendations be made for all couples trying to conceive.

Abstract
RESEARCH QUESTION What is the utilization of direct-to-consumer fertility tests (DTCFT) among fertility patients? How does the perceived utility of DTCFT differ between patients and reproductive endocrinologists (REI)? DESIGN Infertility patients visiting the Duke Fertility Center between December 2020 and December 2021 were sent an electronic invitation to participate in a patient survey. Members of the Society of Reproductive Endocrinology and Infertility were also sent e-mail invitations to participate in the REI survey. DTCFT were defined as tests not ordered by a physician or performed at a physician's office, including calendar methods of ovulation prediction, urinary ovulation prediction kits, basal body temperature (BBT) monitoring, hormone analysis, ovarian reserve testing and semen analysis. Patients and REI were asked how likely they were to recommend a given DTCFT, on a 0-10 Likert scale. RESULTS In total, 425 patients (response rate 50.5%) and 178 REI (response rate 21.4%) completed the surveys. Patients reported the utilization of calendar methods of ovulation prediction (83.8%), urinary ovulation prediction (78.8%), BBT monitoring (30.8%), hormone analysis (15.3%), semen analysis (10.1%) and ovarian reserve testing (9.2%). REI rated the utility of all DTCFT significantly lower than patients did (average discordance -4.2, P < 0.001), except for urinary ovulation prediction, which REI gave a significantly higher score (discordance +1.0, P < 0.001). Prior pregnancy was significantly associated with home ovulation prediction utilization among patients (adjusted odds ratio 3.21, 95% confidence interval 1.2-9.83). CONCLUSIONS Methods of ovulation prediction are commonly used by fertility patients. Significant discordance exists in the perceived utility of DTCFT between patients and REI. Patient education and guidelines are needed to better inform individuals considering DTCFT.

Yu X, Zhang S, Chen L, Zhang XY, Wang Q. High incidence of sexual dysfunction and timed intercourse was found only in infertile males who with known impairment of sperm quality for a long period: evidence from a hospital-based cross-sectional study. Reprod Biol Endocrinol 2022; 20:139. [PMID: 36114509 PMCID: PMC9479282 DOI: 10.1186/s12958-022-01010-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 09/06/2022] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Infertile men with higher sexual dysfunction risk and increased psychological burden, were also associated with more inclined to timed intercourse. Decreased semen quality may have adverse effects on male sexual function. However, it is also likely that many of these sequences do not play a direct role, those negative consequences may depend mainly on the later failed attempting pregnancy. Research is limited in this area. METHODS This cross-sectional study was based on a group of 509 men who were assessed for couple's infertility at the First Hospital of Jilin University between June 2021 and October 2021. All the men completed a comprehensive questionnaire, and then were divided in two groups. Group A included patients who either never received a routine infertility work-up or done so recently within the last 6 months. Group B included patients who previously received a sperm quality assessment at least 6 months or more prior. Patients were further categorized into three subgroups according to the severity of the decreases in their sperm parameters: severe, mild-moderate, and normozoospermic. RESULTS The prevalence of erectile dysfunction was higher in Group B Mild-Moderate and Group B Severe in comparison to Group A (OR=1.86 [1.07-3.24], P = 0.027; OR=5.312 [2.69-10.49], P < 0.001, respectively). No significant differences were found between Group A and Group B-normozoospermic. Similar results were observed in the prevalence of premature ejaculation between the groups. Timed intercourse was seen in 11.8% (20/170) of men in Group A and 16.2% (19/117) in Group B-normozoospermic. It was more commonly practiced among infertile men in Group B-Mild-Moderate and Group B Severe, as 28.2% (44/156) and 25.7% (17/66) of these couples had attempted to conceive through timed intercourse (P < 0.001). CONCLUSIONS Our findings indicate that the severity of sperm quality impairment was negatively associated with sexual dysfunction only in infertile men who with known impairment of sperm quality for a long period. Timed intercourse was more common among these couples. For those individuals had never test their sperm quality, although more than half of these patients showed a decrease in sperm quality, the incidence of sexual dysfunction is relatively low and were comparable to those men examined previously known as normozoospermic.

Abstract
OBJECTIVE To report on the pregnancy outcomes of timed intercourse (TI) with controlled ovarian hyperstimulation (COH) as the first-line treatment of unexplained subfertility, and provide some evidence on the factors involved. METHODS The records of couples treated between January 2016 and March 2019 were retrospectively analyzed. Couples were selected for TI based on standard infertility evaluation. Semen analysis by swim-up was conducted and the total motile sperm count (TMSC) obtained. The main outcome measured was the clinical pregnancy rates. Data were analyzed with t test, Pearson's Chi-squared test, and the Wald test for logistic regression with p≤0.05. RESULTS The records of 275 couples (449 cycles) were included in the analysis. Patients underwent TI up to six attempts. Patient- and cycle-based pregnancy rates were 18.55% and 13.14%, respectively. Eight patients got pregnant twice, resulting in a cumulative pregnancy rate of 21.4%. Women that did not get pregnant demonstrated a statistically higher mean age value than women who did (p=0.0186). Logistic regression indicated that for every year added to the woman's age, the chances of pregnancy reduced by 6.45%, and for cycles with TMSC ≥ 5 million, the chances of pregnancy were 1.91 times higher when compared to TMSC < 5 million. CONCLUSIONS TI with COH should be considered as the first-line treatment for selected couples with unexplained subfertility before more traumatic and costly IVF treatments were considered. The findings can assist doctors to conduct a more educated counselling concerning the chances patients have to get pregnant with TI.

Abstract
BACKGROUND/AIM Infertility is defined as the inability of heterosexual couples to achieve a successful clinically recognizable pregnancy after 12 months or more of regular, unprotected sexual intercourse. Infertility estimations are very important to inform the healthcare policymakers and governments to implement appropriate social and economic policies. Thus, this study aimed to estimate the pooled prevalence of infertility (primary and secondary) and its etiologic factors in Sudan. METHODS This study included all published and unpublished studies written in Arabic or English. Electronic sources (namely, PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov) and nonelectronic sources (direct Google search, Google Scholar, OpenGrey, OATD, WorldCat log, and university websites) were used from their inception to May 16, 2021. A total of 1955 studies were reviewed, of which only 20 studies were eligible for the meta-analysis. Studies were eligible if they provided the prevalence of infertility in Sudan. The Joanna Briggs Institute Quality Assessment Tool was used to evaluate each study. Data synthesis and statistical analysis were conducted using Jeffrey's Amazing Statistics Program version 0.14.1.0. RESULTS The pooled prevalence of overall infertility, primary infertility, and secondary infertility in Sudan were 13% (I2 = 96.45, p < 0.001), 65% (I2 = 98.5, p < 0.001), and 35% (I2 = 98.5, p < 0.001), respectively, and the prevalence of infertility factors were 41%, 27%, 16%, and 17% for female, male, combined factors, and unexplained factors, respectively. Women with infertility were mainly present because of ovulatory disorders (ovulatory factors, 36%; polycystic ovary syndrome, 38%). By contrast, spermatic disorders such as azoospermia (37%), oligozoospermia (30%), and asthenozoospermia (30%) were the main causes of male infertility. CONCLUSION In Sudan, the prevalence of primary infertility is higher than that of secondary infertility. Female factors were the most common causes of infertility in Sudan, and this study found a high prevalence of unexplained factors. Polycystic ovary syndrome and azoospermia were the most common causes of female and male infertility in Sudan, respectively. The interpretation of these findings should take into consideration the presence of substantial heterogeneity between the included studies.

Abstract
Background Many men with HIV (MWH) want to have children. HIV viral suppression minimizes sexual HIV transmission risks while allowing for conception and optimization of the health of men, their partners, and their infants. Objective This study developed and evaluated the feasibility and acceptability of an intervention to promote serostatus disclosure, antiretroviral therapy (ART) uptake and adherence, and viral suppression among MWH who want to have children in South Africa. Methods We developed a safer conception intervention (Sinikithemba Kwabesilisa or We give hope to men) to promote viral suppression via ART uptake and adherence, HIV serostatus disclosure, and other safer conception strategies for MWH in South Africa. Through 3 counseling and 2 booster sessions over 12 weeks, we offered education on safer conception strategies and aided participants in developing a safer conception plan. We recruited MWH (HIV diagnosis known for >1 month), not yet accessing ART or accessing ART for <3 months, in a stable partnership with an HIV-negative or unknown-serostatus woman, and wanting to have a child in the following year. We conducted an open pilot study to evaluate acceptability based on patient participation and exit interviews and feasibility based on recruitment and retention. In-depth exit interviews were conducted with men to explore intervention acceptability. Questionnaires collected at baseline and exit assessed disclosure outcomes; CD4 and HIV-RNA data were used to evaluate preliminary impacts on clinical outcomes of interest. Results Among 31 eligible men, 16 (52%) enrolled in the study with a median age of 29 (range 27-44) years and a median time-since-diagnosis of 7 months (range 1 month to 9 years). All identified as Black South African, with 56% (9/16) reporting secondary school completion and 44% (7/16) reporting full-time employment. Approximately 44% (7/16) of participants reported an HIV-negative (vs unknown-serostatus) partner. Approximately 88% (14/16) of men completed the 3 primary counseling sessions. In 11 exit interviews, men reported personal satisfaction with session content and structure while also suggesting that they would refer their peers to the program. They also described the perceived effectiveness of the intervention and self-efficacy to benefit. Although significance testing was not conducted, 81% (13/16) of men were taking ART at the exit, and 100% (13/13) of those on ART were virally suppressed at 12 weeks. Of the 16 men, 12 (75%) reported disclosure to pregnancy partners. Conclusions These preliminary data suggest that safer conception care is acceptable to men and has the potential to reduce HIV incidence among women and their children while supporting men’s health. Approximately half of the men who met the screening eligibility criteria were enrolled. Accordingly, refinement to optimize uptake is needed. Providing safer conception care and peer support at the community level may help reach men.

Hamilton JAM, van der Steeg JW, Hamilton CJCM, de Bruin JP. A concise infertility work-up results in fewer pregnancies. Hum Reprod Open 2021; 2021:hoab033. [PMID: 34557598 PMCID: PMC8452484 DOI: 10.1093/hropen/hoab033] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 08/09/2021] [Indexed: 01/22/2023] Open
Abstract
STUDY QUESTION Is pregnancy success rate after a concise infertility work-up the same as pregnancy success rate after the traditional extensive infertility work-up? SUMMARY ANSWER The ongoing pregnancy rate within a follow-up of 1 year after a concise infertility work-up is significantly lower than the pregnancy success rate after the traditional and extensive infertility work-up. WHAT IS KNOWN ALREADY Based on cost-effectiveness studies, which have mainly focused on diagnosis, infertility work-up has become less comprehensive. Many centres have even adopted a one-stop approach to their infertility work-up. STUDY DESIGN SIZE DURATION We performed a historically controlled cohort study. In 2012 and 2013 all new infertile couples (n = 795) underwent an extensive infertility work-up (group A). In 2014 and 2015, all new infertile couples (n = 752) underwent a concise infertility work-up (group B). The follow-up period was 1 year for both groups. Complete follow-up was available for 99.0% of couples in group A and 97.5% in group B. PARTICIPANTS/MATERIALS SETTING METHODS The extensive infertility work-up consisted of history taking, a gynaecological ultrasound scan, semen analysis, ultrasonographic cycle monitoring, a timed postcoital test, a timed progesterone and chlamydia antibody titre. A hysterosalpingography (HSG) was advised routinely. The concise infertility work-up was mainly based on history taking, a gynaecological ultrasound scan and semen analysis. A HSG was only performed if tubal pathology was suspected or before the start of IUI. Laparoscopy and hormonal tests were only performed if indicated. Couples were treated according to the diagnosis with either expectant management (if the Hunault prognostic score was >30%), ovulation induction (in case of ovulation disorders), IUI in natural cycles (in case of cervical factor), IUI in stimulated cycles (if the Hunault prognostic score was <30%) or IVF/ICSI (in case of tubal factor, advanced female age, severe male factor and if other treatments remained unsuccessful). The primary outcomes were time to pregnancy and the ongoing pregnancy rates in both groups. The secondary outcomes were the number of investigations, the distribution of diagnoses made, the first treatment (started) after infertility work-up and the mode of conception. MAIN RESULTS AND THE ROLE OF CHANCE The descriptive data, such as age, duration of infertility, type of infertility and lifestyle habits, in both groups were comparable. In group A, more than twice the number of infertility investigations were performed, compared to group B. An HSG was made less frequently in group B (33% versus 42%) and at a later stage. A Kaplan-Meier curve shows a shorter time to pregnancy in group A. Also, a significantly higher overall ongoing pregnancy rate within a follow-up of 1 year was found in group A (58.7% versus 46.8%, respectively, P < 0.001). In group A, more couples conceived during the infertility work-up (14.7% versus 6.5%, respectively, P < 0.05). The diagnosis cervical infertility could only be made in group A (9.3%). The diagnosis unexplained infertility differed between groups, at 23.5% in group A and 32.2% in group B (P < 0.001). LIMITATIONS REASONS FOR CAUTION This was a historically controlled cohort study; introduction of bias cannot be ruled out. The follow-up rate was similar in the two groups and therefore could not explain the differences in pregnancy rate. WIDER IMPLICATIONS OF THE FINDINGS Re-introduction of an extensive infertility work-up should be considered as it may lead to higher ongoing pregnancy rates within a year. The therapeutic effects of HSG and timing of intercourse may improve the fertility chance. This finding should be verified in a randomized controlled trial. STUDY FUNDING/COMPETING INTERESTS No funding was obtained for this study. No conflicts of interest were declared. TRIAL REGISTRATION NUMBER N/A.

BMC Pregnancy Childbirth 2021; 21:495.

Abstract
BACKGROUND Restorative reproductive medicine (RRM) seeks to identify and correct underlying causes and factors contributing to infertility and reproductive dysfunction. Many components of RRM are highly suitable for primary care practice. We studied the outcomes amongst couples who received restorative reproductive medicine treatment for infertility in a primary care setting. METHODS Two family physicians in Massachusetts trained in a systematic approach to RRM (natural procreative technology, or NaProTechnology) treated couples with infertility. We retrospectively reviewed the characteristics, diagnoses, treatments, and outcomes for all couples treated during the years 1989 to 2014. We compared pregnancy and live birth by clinical characteristics using Kaplan-Meier analysis. We employed the Fleming-Harrington weighted Renyi test or the logrank test to compare the cumulative proportion with pregnancy or with live birth. RESULTS Among 370 couples beginning treatment for infertility, the mean age was 34.8 years, the mean prior time trying to conceive was 2.7 years, and 27% had a prior live birth. The mean number of diagnoses per couple was 4.9. Treatment components included fertility tracking with the Creighton Model FertilityCare System (80%); medications to enhance cervical mucus production (81%), to stimulate ovulation (62%), or to support the luteal phase (75%); and referral to female laparoscopy by a surgeon specializing in endometriosis (46%). The cumulative live birth rate at 2 years was 29% overall; this was significantly higher for women under age 35 (34%), and for women with body mass index < 25 (40%). There were 2 sets of twins and no higher-order multiple gestations. Of the 63 births with data available, 58 (92%) occurred at term. CONCLUSIONS Family physicians can provide a RRM approach for infertility to identify underlying causes and promote healthy term live births. Younger women and women with body mass index < 25 are more likely to have a live birth.

Perez Capotosto M. An Integrative Review of Fertility Knowledge and Fertility-Awareness Practices Among Women Trying to Conceive. Nurs Womens Health 2021; 25:198-206. [PMID: 33961806 DOI: 10.1016/j.nwh.2021.04.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 12/09/2020] [Accepted: 01/01/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To synthesize the literature on fertility knowledge and fertility-awareness among women seeking pregnancy. DATA SOURCES The search terms "fertility-awareness OR fertility knowledge AND women AND subfertile OR infertile OR seeking pregnancy OR trying to conceive OR pre-conception OR conception NOT contraception NOT birth control" were used via CINAHL, PubMed, and Web of Science. Primary research studies were considered in the search parameters. STUDY SELECTION Searches yielded 116 studies published between 1978 and 2020. After screening, 43 full-text studies were assessed for eligibility, 35 of which were omitted as not relevant. Nine quantitative studies using cross-sectional designs met this review's inclusion criteria. DATA EXTRACTION Studies were reviewed for information on the relationship between fertility knowledge/fertility-awareness and pregnancy intention. Studies examining the results of fertility-awareness based method (FABM) efficacy, FABMs for contraception, and provider knowledge regarding FABMs were omitted. DATA SYNTHESIS Analysis showed low knowledge regarding the identification of the fertile window in the menstrual cycle to optimize pregnancy. There was moderate general knowledge on fertility (e.g., infertility definition, age of fertility decline, etc.). Use of an FABM and education regarding FABMs were infrequent, yet participants recognized that it would be beneficial to use and learn when trying to conceive. CONCLUSION Women seeking pregnancy have low to moderate fertility knowledge. More research is necessary on the relationship between fertility knowledge/fertility-awareness and unexplained infertility. Nurses, nurse practitioners, and nurse-midwives should provide education on FABMs to women when they first report difficulty achieving pregnancy. Clinicians' approaches toward FABM education for women and how to implement FABM education into the preconception visit are important areas for future research.

Sporadic anovulation is not an important determinant of becoming pregnant and time to pregnancy among eumenorrheic women: A simulation study. Paediatr Perinat Epidemiol 2021; 35:143-152. [PMID: 32970334 PMCID: PMC7854799 DOI: 10.1111/ppe.12692] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 04/23/2020] [Accepted: 04/26/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND Attaining pregnancy is conditional upon a series of complex processes, including adequately timed intercourse, ovulation, fertilisation, and implantation. Anovulation is a first-line treatment target for couples with difficulty conceiving and is frequently examined in studies of fecundability. OBJECTIVES To identify whether sporadic anovulation is an important determinant of cumulative pregnancy rates and time to pregnancy among fertile women with regular menstrual cycles. METHODS We simulated cumulative pregnancy rates and time to pregnancy for 12 consecutive menstrual cycles among 100 000 women based on data-driven probabilities of implantation, fertilisation, ovulation, and intercourse occurring in the fertile window. We assumed anovulation probabilities of 1%, 8%, or 14.5% and intercourse averaging once per week, every other day, or daily. The model incorporated reductions in implantation and fertilisation rates for successive cycles of non-pregnancy. RESULTS After 12 cycles, a reduction in the per cycle incidence of anovulation from 14.5% to 1% resulted in a 4.0% higher cumulative pregnancy rate (86.7% vs 90.7%) and similar time to pregnancy (1-cycle median difference). In contrast, increasing mean unscheduled sexual intercourse frequency from weekly to every other day was associated with a 5-cycle median reduction in time to pregnancy (weekly: 7 cycles; every other day or daily: 2 cycles) and a 28.9% increase in the cumulative pregnancy rate (weekly: 59.9%, every other day: 88.8%; daily: 91.6%). CONCLUSIONS In presumed fertile women with regular menstrual cycles, routine investigation of anovulation may not be an informative outcome in studies of fecundability, and routine testing to ensure ovulation and treatment of anovulation are unlikely to be medically necessary. While biomarkers or cervical fluid may help time intercourse to the fertile window, time to pregnancy can also be improved through increasing the frequency of unscheduled intercourse. These findings need corroboration in large preconception time to pregnancy studies.

[PMID: 32910202 PMCID: PMC7518709 DOI: 10.1093/humrep/deaa176] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 05/06/2020] [Indexed: 11/12/2022] Open
Abstract
STUDY QUESTION To what extent does the use of mobile computing apps to track the menstrual cycle and the fertile window influence fecundability among women trying to conceive? SUMMARY ANSWER After adjusting for potential confounders, use of any of several different apps was associated with increased fecundability ranging from 12% to 20% per cycle of attempt. WHAT IS KNOWN ALREADY Many women are using mobile computing apps to track their menstrual cycle and the fertile window, including while trying to conceive. STUDY DESIGN, SIZE, DURATION The Pregnancy Study Online (PRESTO) is a North American prospective internet-based cohort of women who are aged 21-45 years, trying to conceive and not using contraception or fertility treatment at baseline. PARTICIPANTS/MATERIALS, SETTING, METHODS We restricted the analysis to 8363 women trying to conceive for no more than 6 months at baseline; the women were recruited from June 2013 through May 2019. Women completed questionnaires at baseline and every 2 months for up to 1 year. The main outcome was fecundability, i.e. the per-cycle probability of conception, which we assessed using self-reported data on time to pregnancy (confirmed by positive home pregnancy test) in menstrual cycles. On the baseline and follow-up questionnaires, women reported whether they used mobile computing apps to track their menstrual cycles ('cycle apps') and, if so, which one(s). We estimated fecundability ratios (FRs) for the use of cycle apps, adjusted for female age, race/ethnicity, prior pregnancy, BMI, income, current smoking, education, partner education, caffeine intake, use of hormonal contraceptives as the last method of contraception, hours of sleep per night, cycle regularity, use of prenatal supplements, marital status, intercourse frequency and history of subfertility. We also examined the impact of concurrent use of fertility indicators: basal body temperature, cervical fluid, cervix position and/or urine LH. MAIN RESULTS AND THE ROLE OF CHANCE Among 8363 women, 6077 (72.7%) were using one or more cycle apps at baseline. A total of 122 separate apps were reported by women. We designated five of these apps before analysis as more likely to be effective (Clue, Fertility Friend, Glow, Kindara, Ovia; hereafter referred to as 'selected apps'). The use of any app at baseline was associated with 20% increased fecundability, with little difference between selected apps versus other apps (selected apps FR (95% CI): 1.20 (1.13, 1.28); all other apps 1.21 (1.13, 1.30)). In time-varying analyses, cycle app use was associated with 12-15% increased fecundability (selected apps FR (95% CI): 1.12 (1.04, 1.21); all other apps 1.15 (1.07, 1.24)). When apps were used at baseline with one or more fertility indicators, there was higher fecundability than without fertility indicators (selected apps with indicators FR (95% CI): 1.23 (1.14, 1.34) versus without indicators 1.17 (1.05, 1.30); other apps with indicators 1.30 (1.19, 1.43) versus without indicators 1.16 (1.06, 1.27)). In time-varying analyses, results were similar when stratified by time trying at study entry (<3 vs. 3-6 cycles) or cycle regularity. For use of the selected apps, we observed higher fecundability among women with a history of subfertility: FR 1.33 (1.05-1.67). LIMITATIONS, REASONS FOR CAUTION Neither regularity nor intensity of app use was ascertained. The prospective time-varying assessment of app use was based on questionnaires completed every 2 months, which would not capture more frequent changes. Intercourse frequency was also reported retrospectively and we do not have data on timing of intercourse relative to the fertile window. Although we controlled for a wide range of covariates, we cannot exclude the possibility of residual confounding (e.g. choosing to use an app in this observational study may be a marker for unmeasured health habits promoting fecundability). Half of the women in the study received a free premium subscription for one of the apps (Fertility Friend), which may have increased the overall prevalence of app use in the time-varying analyses, but would not affect app use at baseline. Most women in the study were college educated, which may limit application of results to other populations. WIDER IMPLICATIONS OF THE FINDINGS Use of a cycle app, especially in combination with observation of one or more fertility indicators (basal body temperature, cervical fluid, cervix position and/or urine LH), may increase fecundability (per-cycle pregnancy probability) by about 12-20% for couples trying to conceive. We did not find consistent evidence of improved fecundability resulting from use of one specific app over another.

The impact of disturbances in natural conception cycles. Arch Gynecol Obstet 2020; 301:1069-1080.

Abstract
PURPOSE Many physicians and other healthcare professionals are often asked questions on interfering factors for conception by couples with a desire for children. Such possible disturbances include, for example, the very common minor diseases, stress and also sexual intercourse during the suspected implantation period. Non-scientifically based statements about disturbances in conception cycles, as found in many layman publications and on the internet, can strongly unsettle couples with a desire for children and force them into corset of rules of conduct. Therefore, a systematic scientific evaluation of the impact of disturbances on conception is urgently needed. METHODS A search for possible disturbances in natural conception cycles together with up to three of the respective pre-cycles in a large cycle database from users of the symptothermal method of natural family planning in Germany was performed. Disturbances were qualified by scientific panel decision and analysed statistically with their effects on the chances of spontaneous conception. Mixed logistical regression models and survival time analyses were used. RESULTS A total of 237 women with a total of 747 cycles could be included in the analysis. In 61% of all 237 conception cycles, disturbances occurred. The statistical analysis shows that disturbances in natural conception cycles unexpectedly increase the likelihood of pregnancy by an overall factor of 1.32 (95% CI 1.04-1.70). Sexual intercourse in the window of implantation does not decrease the chances of conception. Relaxation states at the time of ovulation and/or during the implantation period have no representable effect and do not increase the chance of pregnancy. CONCLUSIONS Couples trying to conceive should at least be informed that disturbances in conception cycles, such as minor diseases, stress or sexual intercourse during the implantation period do not interfere with conception. Relaxation has no effect in favour of success. This takes away the guilty feeling of couples, fearing that they possibly did something wrong in cycles without the desired pregnancy.

Abstract
Failure of embryo implantation accounts for a significant percentage of female infertility. Exquisitely coordinated molecular programs govern the interaction between the competent blastocyst and the receptive uterus. Decidualization, the rapid proliferation and differentiation of endometrial stromal cells into decidual cells, is required for implantation. Decidualization defects can cause poor placentation, intrauterine growth restriction, and early parturition leading to preterm birth. Decidualization has not yet been systematically studied at the genetic level due to the lack of a suitable high-throughput screening tool. Herein we describe the generation of an immortalized human endometrial stromal cell line that uses yellow fluorescent protein under the control of the prolactin promoter as a quantifiable visual readout of the decidualization response (hESC-PRLY cells). Using this cell line, we performed a genome-wide siRNA library screen, as well as a screen of 910 small molecules, to identify more than 4,000 previously unrecognized genetic and chemical modulators of decidualization. Ontology analysis revealed several groups of decidualization modulators, including many previously unappreciated transcription factors, sensory receptors, growth factors, and kinases. Expression studies of hits revealed that the majority of decidualization modulators are acutely sensitive to ovarian hormone exposure. Gradient treatment of exogenous factors was used to identify EC50 values of small-molecule hits, as well as verify several growth factor hits identified by the siRNA screen. The high-throughput decidualization reporter cell line and the findings described herein will aid in the development of patient-specific treatments for decidualization-based recurrent pregnancy loss, subfertility, and infertility.

Abstract
Introduction To inform the WHO Guideline on self-care interventions, we conducted a systematic review of the impact of ovulation predictor kits (OPKs) on time-to-pregnancy, pregnancy, live birth, stress/anxiety, social harms/adverse events and values/preferences. Methods Included studies had to compare women desiring pregnancy who managed their fertility with and without OPKs, measure an outcome of interest and be published in a peer-reviewed journal. We searched for studies on PubMed, CINAHL, LILACS and EMBASE through November 2018. We assessed risk of bias assessed using the Cochrane tool for randomised controlled trials (RCTs) and the Evidence Project tool for observational studies, and conducted meta-analysis using random effects models to generate pooled estimates of relative risk (RR). Results Four studies (three RCTs and one observational study) including 1487 participants, all in high-income countries, were included. Quality of evidence was low. Two RCTs found no difference in time-to-pregnancy. All studies reported pregnancy rate, with mixed results: one RCT from the 1990s among couples with unexplained or male-factor infertility found no difference in clinical pregnancy rate (RR: 1.09, 95% CI 0.51 to 2.32); two more recent RCTs found higher self-reported pregnancy rates among OPK users (pooled RR: 1.40, 95% CI 1.08 to 1.80). A small observational study found higher rates of pregnancy with lab testing versus OPKs among women using donor insemination services. One RCT found no increase in stress/anxiety after two menstrual cycles using OPKs, besides a decline in positive affect. No studies measured live birth or social harms/adverse events. Six studies presented end-users’ values/preferences, with almost all women reporting feeling satisfied, comfortable and confident using OPKs. Conclusion A small evidence base, from high-income countries and with high risk of bias, suggests that home-based use of OPKs may improve fertility management when attempting to become pregnant with no meaningful increase in stress/anxiety and with high user acceptability. Systematic review registration number PROSPERO registration number CRD42019119402.

Abstract
Objective To determine the effectiveness of achieving pregnancy with focused intercourse in the fertile window identified using natural fertility indicators. Methods 24-cycle prospective effectiveness study. Setting A North American web-based fertility monitoring service. Participants 256 North American women aged 20–43 (mean age 29.2 years) seeking to achieve pregnancy. Intervention Participants identified their fertile window with either electronic hormonal fertility monitoring or cervical mucus monitoring, or both, and recorded their observations on an online fertility tracking system. Main outcome measures Pregnancies were validated by nurses with an online self-assessed pregnancy evaluation form. Survival analysis was used to determine pregnancy rates. Results There were 150 pregnancies among the 256 participants with an overall pregnancy rate of 78 per 100 women over 12 menstrual cycles. There were 54 pregnancies (68%) among the 80 women using the fertility monitor, 11 pregnancies (46%) among the 24 women using mucus monitoring, and 90 (63%) among the 143 women using both mucus and monitor. The 12-cycle pregnancy rates per 100 women were 83 (monitor group), 72 (mucus group), and 75 (mucus and monitor group). Pregnancy rates reached 100% at 24 cycles of use for those women using the hormonal fertility monitor. Conclusion Use of the hormonal fertility monitor alone seems to offer the best natural estimate of the fertile phase of the menstrual cycle for women wishing to achieve a pregnancy. Focusing intercourse through 24 menstrual cycles can be beneficial for achieving pregnancy.

Abstract
The ability to identify the precise time of ovulation is important for women who want to plan conception or practice contraception. Here, we review the current literature on various methods for detecting ovulation including a review of point‐of‐care device technology. We incorporate an examination of methods to detect ovulation that have been developed and practiced for decades and analyze the indications and limitations of each—transvaginal ultrasonography, urinary luteinizing hormone detection, serum progesterone and urinary pregnanediol 3‐glucuronide detection, urinary follicular stimulating hormone detection, basal body temperature monitoring, and cervical mucus and salivary ferning analysis. Some point‐of‐care ovulation detection devices have been developed and commercialized based on these methods, however previous research was limited by small sample size and an inconsistent standard reference to true ovulation.

Arch Gynecol Obstet 2017; 295:1015-1024.

Abstract
PURPOSE To analyze cumulative pregnancy rates of subfertile couples after fertility awareness training. METHODS A prospective observational cohort study followed 187 subfertile women, who had received training in self-observation of the fertile phase of the menstrual cycle with the Sensiplan method, for 8 months. The women, aged 21-47 years, had attempted to become pregnant for 3.5 years on average (range 1-8 years) before study entry. Amenorrhea, known tubal occlusion and severe male factor had been excluded. An additional seven women, who had initially been recruited, became pregnant during the cycle immediately prior to Sensiplan training: this is taken to be the spontaneous pregnancy rate per cycle in the cohort in the absence of fertility awareness training. RESULTS The cumulative pregnancy rate of subfertile couples after fertility awareness training was 38% (95% CI 27-49%; 58 pregnancies) after eight observation months, which is significantly higher than the estimated basic pregnancy rate of 21.6% in untrained couples in the same cohort. For couples who had been seeking to become pregnant for 1-2 years, the pregnancy rate increased to 56% after 8 months. A female age above 35 (cumulative pregnancy rate 25%, p = 0.06), couples who had attempted to become pregnant for more than 2 years (cumulative pregnancy rate 17%, p < 0.01), all significantly reduce the chances of conceiving naturally at some point. CONCLUSIONS Training women to identify their fertile window in the menstrual cycle seems to be a reasonable first-line therapy in the management of subfertility.

Cortical mechanics and myosin-II abnormalities associated with post-ovulatory aging: implications for functional defects in aged eggs. Mol Hum Reprod 2016; 22:397-409. [PMID: 26921397 PMCID: PMC4884917 DOI: 10.1093/molehr/gaw019] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2016] [Revised: 02/12/2016] [Accepted: 02/24/2016] [Indexed: 12/20/2022] Open
Abstract
STUDY HYPOTHESIS Cellular aging of the egg following ovulation, also known as post-ovulatory aging, is associated with aberrant cortical mechanics and actomyosin cytoskeleton functions. STUDY FINDING Post-ovulatory aging is associated with dysfunction of non-muscle myosin-II, and pharmacologically induced myosin-II dysfunction produces some of the same deficiencies observed in aged eggs. WHAT IS KNOWN ALREADY Reproductive success is reduced with delayed fertilization and when copulation or insemination occurs at increased times after ovulation. Post-ovulatory aged eggs have several abnormalities in the plasma membrane and cortex, including reduced egg membrane receptivity to sperm, aberrant sperm-induced cortical remodeling and formation of fertilization cones at the site of sperm entry, and reduced ability to establish a membrane block to prevent polyspermic fertilization. STUDY DESIGN, SAMPLES/MATERIALS, METHODS Ovulated mouse eggs were collected at 21-22 h post-human chorionic gonadotrophin (hCG) (aged eggs) or at 13-14 h post-hCG (young eggs), or young eggs were treated with the myosin light chain kinase (MLCK) inhibitor ML-7, to test the hypothesis that disruption of myosin-II function could mimic some of the effects of post-ovulatory aging. Eggs were subjected to various analyses. Cytoskeletal proteins in eggs and parthenogenesis were assessed using fluorescence microscopy, with further analysis of cytoskeletal proteins in immunoblotting experiments. Cortical tension was measured through micropipette aspiration assays. Egg membrane receptivity to sperm was assessed in in vitro fertilization (IVF) assays. Membrane topography was examined by low-vacuum scanning electron microscopy (SEM). MAIN RESULTS AND THE ROLE OF CHANCE Aged eggs have decreased levels and abnormal localizations of phosphorylated myosin-II regulatory light chain (pMRLC; P = 0.0062). Cortical tension, which is mediated in part by myosin-II, is reduced in aged mouse eggs when compared with young eggs, by ∼40% in the cortical region where the metaphase II spindle is sequestered and by ∼50% in the domain to which sperm bind and fuse (P < 0.0001). Aging-associated parthenogenesis is partly rescued by treating eggs with a zinc ionophore (P = 0.003), as is parthenogenesis induced by inhibition of mitogen-activated kinase (MAPK) 3/1 [also known as extracellular signal-regulated kinase (ERK)1/2] or MLCK. Inhibition of MLCK with ML-7 also results in effects that mimic those of post-ovulatory aging: fertilized ML-7-treated eggs show both impaired fertilization and increased extents of polyspermy, and ML-7-treated young eggs have several membrane abnormalities that are shared by post-ovulatory aged eggs. LIMITATIONS, REASONS FOR CAUTION These studies were done with mouse oocytes, and it remains to be fully determined how these findings from mouse oocytes would compare with other species. For studies using methods not amenable to analysis of large sample sizes and data are limited to what images one can capture (e.g. SEM), data should be interpreted conservatively. WIDER IMPLICATIONS OF THE FINDINGS These data provide insights into causes of reproductive failures at later post-copulatory times. LARGE SCALE DATA Not applicable. STUDY FUNDING AND COMPETING INTERESTS This project was supported by R01 HD037696 and R01 HD045671 from the NIH to J.P.E. Cortical tension studies were supported by R01 GM66817 to D.N.R. The authors declare there are no financial conflicts of interest.
