Inflammatory cytokines in maternal serum between women with threatened miscarriage and normal pregnancy.

OBJECTIVE: To compare the levels of proinflammatory cytokines in women with threatened miscarriage and normal pregnancy. METHODS: This study was a longitudinal study. Consenting women with normal pregnancy and those admitted on account of threatened miscarriage at an estimated gestational age of 6-10 weeks were included in the study. The proinflammatory cytokines interleukin-2 (IL-2) and interferon-γ (IFN-γ) and the anti-inflammatory cytokines IL-4 and IL-13 were measured at the diagnosis of threatened miscarriage (baseline) and in the 13th week of pregnancy. The χ2 test of association was used to examine the relationship between the pregnancy type and demographic characteristics; clinical history and gynecologic history. Student t test was used to compare the selected cytokine between women with threatened miscarriage and normal pregnancy. RESULTS: There was a significantly higher IL-2 (P = 0.033), IFN-γ (P < 0.001), and IL-13 (P < 0.001) in women with threatened miscarriage than in women with normal pregnancy at the baseline. At the follow up, the results revealed a significantly higher IFN-γ level (P < 0.001) and IL-4 (P = 0.019) in women with threatened miscarriage than in women with normal pregnancies. CONCLUSION: Proinflammatory cytokine profiles were associated with a higher risk of threatened miscarriage.

Low birth weight and its associated factors in East Gojjam Zone, Amhara, Ethiopia.

INTRODUCTION: Low birth weight is a global public health problem, with 15-20% of all births globally, described by weight at birth of less than 2500 g ensuing fetal and neonatal mortality and morbidity, poor cognitive growth, and an increased risk of chronic diseases later in life. The prevalence is critical in East Africa where about 11% have low birth weight out of 54% of neonates whose weight was measured at birth. There are many causes of low birth weight, including early induction of labor or cesarean birth, multiple pregnancies, infections, diabetes, and high blood pressure. Moreover, socioeconomic factors and unhealthy dietary habits could contribute to low birth weight in areas with poor intake of a diversified diet. This study has indicated the association between poor dietary diversity and low birth weight in the study area for the first time. METHODS: An institutional-based cross-sectional study was conducted on eligible 423 pregnant women recruited from Gestational Age of less than 17 weeks until delivery where the birth outcomes were recorded in health institutions in randomly selected five Woredas in East Gojjam Zone, Amhara, Ethiopia from June 2019 to December 2020. Questionnaires were used to collect data on socio-economic-demographic, dietary diversity scores, and food consumption scores. RESULTS: The study found a prevalence of low birth weight of 9.6%, low dietary diversity score of 53.2%, low food consumption score of 19.7%, and preterm delivery of 9.1%. Ever attended school and a higher level of education (diploma and above) decreased the risk of low birth weight with an Adjusted Odds Ratio (AOR) of 0.149 (0.024, 0.973) P ≤ 0.042; 0.059 (0.007, 0.513) P ≤ 0.007; whereas low dietary diversity score group and low food consumption group increased the risk of low birth weight with AOR 2.425 (1.342, 6.192) P ≤ 0.011and 2.983 (1.956, 9.084) P ≤ 0.044 respectively. CONCLUSION AND RECOMMENDATION: Participants with no formal education, no diploma, and above (no college or university training/degree), low diversity score group, and low food consumption group had an increased risk of low birth weight. Therefore the use of a diversified diet, educating women to a higher educational level, and health education on the intake of a diversified food rich in multiple micronutrients are recommended as strategies that will ameliorate the occurrence of low birth weight.

Adverse maternal outcomes of adolescent pregnancy in Northwest Ethiopia: A prospective cohort study.

BACKGROUND: Adolescent pregnancy is considered a major contributor to maternal and child morbidity and mortality, the greatest concern of developing countries and an important public health issue globally. Adolescents are responsible for eleven percent of births worldwide and they face several pregnancy and childbirth related complications. However, in low-income countries like Ethiopia, there are limited researches conducted to investigate outcomes of adolescent pregnancy. Therefore, this study was conducted to assess the adverse maternal outcomes of adolescent pregnancy in Northwest Ethiopia. METHODS: A prospective cohort study was conducted in 12 health facilities from seven districts in East Gojjam zone, Northwest Ethiopia. A total of 418 adolescents (15-19 years old) and 836 adult women (20-34 years old) who attended randomly selected health facilities in East Gojjam zone were included. Data were collected starting from admission to the maternity ward for labor and delivery, and postnatal depression was measured at six weeks' postpartum period using the Edinburgh Postnatal Depression Scale. Generalized estimating equations (GEE) was used to account for the within subject correlation and assess the effect of different known factors that could influence the outcome of this study. RESULTS: A lower percentage of adolescent (58.4%) than adult (71.2%) women had their first antenatal care booking before 16 weeks of gestation. After adjusting for different confounding factors, the adverse outcome that was significantly associated with adolescent pregnancy was postpartum depression (AOR: 2.29; 95% CI, 1.42, 3.7, p-value = 0.001). Assisted vaginal delivery (AOR: 0.44; 95% CI, 0.23, 0.86, p-value 0.016) and cesarean section (AOR: 0.43; 95% CI, 0.19, 0.97, p-value = 0.042) were significantly lower among adolescent women. CONCLUSIONS: Adolescent pregnancy is associated with higher odds of postpartum depression, and lower odds to undergo cesarean section and assisted vaginal delivery than adult women. Perinatal care services should be more adolescent-friendly to ensure early diagnosis and treatment of postpartum depression. School and community-based awareness programs regarding use of contraception to prevent unwanted adolescent pregnancy, early antenatal care booking and adverse pregnancy outcomes of adolescent pregnancy and provision of psychosocial support are recommended.

Trends and determinants of teenage childbearing in Ethiopia: evidence from the 2000 to 2016 demographic and health surveys.

BACKGROUND: Teenage childbearing among adolescents aged 15 to 19 is a common sexual and reproductive health (SRH) issue among young people, particularly in developing countries. It is associated with higher maternal and neonatal complications. Almost half (47%) of the population in Ethiopia are young people under 15 years old. Therefore, a clear understanding of the trend and determinants of teenage childbearing is essential to design proper intervention programs. METHODS: Secondary analysis of the 2000 to 2016 Ethiopia Demographic and Health Survey (DHS) data were conducted. A total of 3710 (DHS 2000), 3266 (DHS 2005), 4009 (DHS 2011) and 3381 (DHS 2016) adolescents (aged 15 to 19 years old) were included from the four surveys. The main outcome variable of this study was teenage childbearing, and independent variables were categorized into individual- and community-level factors. The 2016 DHS was used to identify the factors associated with teenage childbearing. Multi-level logistic regression analysis technique was used to identify the factors associated with teenage childbearing. The analysis was adjusted for different individual- and community- level factors affecting teenage childbearing. Data analysis was conducted using STATA software. RESULTS: The prevalence of adolescents who started childbearing reduced from 16.3% in 2000 DHS to 12.5% in 2016 DHS, p-value = < 0.0001. From the 2016 DHS, the percentage of adolescents who have had a live birth was 10.1%, and the percentage of adolescents who were currently pregnant was 2.4%. The highest percentage of teenage childbearing was in Affar region (23.4%), and the lowest was in Addis Ababa city (3%). The odds of teenage childbearing was higher among adolescents in the age range of 18-19 years old (AOR = 2.26; 95% CI: 1.29, 3.94, p-value < 0.01), those who started sexual intercourse before their eighteenth birthday (AOR = 12.74; 95% CI: 4.83, 33.62, p-value < 0.001), who were married or living together (AOR = 8.98; 95% CI: 2.49, 32.41, p-value < 0.01), and among those who were widowed, divorced or separated (AOR = 4.89; 95% CI: 1.36, 17.61, p-value < 0.05). CONCLUSIONS: One in ten teenage girls have already started childbearing in Ethiopia. Variations were observed in the percentage of teenage childbearing across different sociodemographic- and economic variables. Factors like age, early sexual initiation before 18 years of age, ever married, and geographical region were significant factors associated with teenage childbearing. School- and community- based intervention programs aimed at prevention of early marriage and early sexual intercourse is essential to reduce teenage childbearing and its complications.

Effect of enhanced reminders on postnatal clinic attendance in Addis Ababa, Ethiopia: a cluster randomized controlled trial.

Background: Failure to attend maternal health services is an intractable challenge for the health-care system in low- and middle-income countries. The use of technology for reminding patients about their appointments has been demonstrated to be an effective (future) tool toward increased health care services utilization in developing countries, such as Ethiopia. Objective: We aimed to investigate the effect of enhanced reminders on postnatal care attendance versus usual care (notification of an appointment at discharge). Methods: The study was a cluster randomized controlled trial: out of eligible 86 health centers, 16 health centers in Addis Ababa (AA) were randomized to either the intervention (8) or the control (8) groups; with a total of 350 mothers equally randomized into each arm. Mothers in the intervention group received the SMS (short message service) or a voice call reminder at 48 and 24 hours before the due postnatal appointment, whereas the control group received only the usual notification of appointments provided by health professionals at discharge from the ward following delivery. We recruited participants on wards after delivery at discharge and followed them up to 6 weeks. This study's primary outcome was postnatal visit compliance. Our assessment consisted of a two-level bivariate and a multivariate ordinal logistic regression analysis. Results: The majority (97.7%) of the participants completed the study; 173(98.9%) of women in the intervention group and 169 (96.5%) of women in the control group. There was a statistically significant difference in postnatal care (PNC) compliance among women who were in the intervention versus the control group (p-value = 0.005). Higher odds of postnatal compliance was observed among the intervention group (AOR:2.98, 95% CI 1.51-5.8). Conclusions: Mobile phone reminders were effective in terms of enhancing adherence to PNC appointments. This indicates integration of mobile phone reminders in postnatal care could improve postnatal appointment compliance.

Factors associated with antenatal care services utilisation patterns amongst reproductive age women in Benin Republic: An analysis of 2011/2012 benin republic's demographic and health survey data.

BACKGROUND: High maternal and neonatal mortality persist in Benin Republic despite recent improvements. Numerous women and newborns continue to suffer preventable deaths. Although factors associated with the attendance of at least one antenatal care (ANC) visit are well documented, there is little evidence on factors related to compliance with World Health Organization (WHO) recommended four ANC visits. The present study determined the extent to which reproductive age mothers received the ANC check-ups at a health facility focussing on the WHO-recommended regimen. METHODS: We examined factors related to ANC services utilisation patterns amongst 8701 women recruited in the 2011/2012 Benin Demographic and Health Survey data using multinomial logistic regression. RESULTS: The percentage of mothers with full ANC attendance was 59.56%, 27.61% received less than 4 visits and 12.84% had never attended ANC services. Results showed that out of 13 variables assessed, only the place of residence was not associated with ANC seeking. Amongst significant variables, household wealth index, female education and desire for pregnancy were the most important factors related to ANC services seeking, especially for the achievement of WHO recommended four ANC visits. The relative risk ratio of ANC attendance, for the achievement of WHO recommended four ANC regimens was high amongst mothers from economically well-off households (adjusted relative risk ratio [aRRR] for richest women = 10.6, 95% confidence interval [CI]: 6.16-18.33), educated women (aRRR for primary level = 4.34, 95% CI: 3.00-6.27) and those with desired pregnancies (aRRR = 3.4, 95% CI: 2.58-4.48). CONCLUSION: To achieve WHO-recommended minimum four ANC visits in Benin Republic, our findings suggest the need to financially support the most economically disadvantaged pregnant women and their families during pregnancy, advocate for reducing unmet needs for family planning, strengthen girls' education, especially by maintaining them in school till completion of at least the secondary school.

Gender-Based Violence among Married Women in Debre Tabor Town, Northwest Ethiopia: A Qualitative Study.

Gender-based violence is one of the major public health problems in Ethiopia. This study aimed to assess the perception and attitude of the community towards gender-based violence among married women in Northwest Ethiopia. A qualitative study was conducted using the purposive sampling technique for the three focus group discussions and ten in-depth interviews among married women. Data was analyzed thematically using version 3.4 of the Open Code Software. Most of the participants perceived that gender-based violence was acceptable in the community, violent acts needed to be considerably tolerated rather than condemned. Additionally, participants perceived that the consequences of gender-based violence were mild, and its elimination was difficult. Domestic violence was found to be common, marital rape was not clearly understood, and there was no tendency to disapprove it. This study revealed that the attitude of people and traditional norms played the major role in determining the acceptability of gender-based violence on married women. Increasing awareness on the consequences of gender-based violence, strengthening of women empowerment, involving different stakeholders on the provision of education, amending and enforcing the existing laws, and providing professional help to stop or reduce violence against women are recommended.

A comparative study of azithromycin and sulphadoxine-pyrimethamine as prophylaxis against malaria in pregnancy.

CONTEXT: The benefit of malaria prophylaxis in pregnancy is threatened by emergence of Plasmodium falciparum resistance to antimalarial agents for chemoprophylaxis and treatment. AIM: This study aimed to compare the effectiveness of azithromycin (AZ) with sulphadoxine-pyrimethamine (SP) for malaria prevention. SETTINGS AND DESIGN: A prospective comparative study of antenatal clinic attendees at the University College Hospital, Ibadan, Nigeria. Participants were randomised to receive SP or AZ. SUBJECTS AND METHODS: The subjects were antenatal attendees and Samples for malaria parasitaemia were collected and repeated at follow-up visits; maternal peripheral blood film, placental and cord blood samples were collected at delivery. STATISTICAL ANALYSIS USED: Chi-square test and t-test in a per-protocol analysis. RESULTS: Of 200 participants (100 in each group), 166 (83.0%) completed the study: 86 (86.0%) of SP and 80 (80.0%) of AZ groups, respectively (P = 0.26). Four (4.7%) participants who had SP compared to five (6.2%) in AZ group developed malaria at mean gestational ages of 30.3 ± 1.56 and 33.0 ± 8.6, respectively (P = 0.56). Positive peripheral, placental and cord blood parasitaemia were found in ≤2% of the participants. Drug tolerability and foetal outcomes were comparable for both groups. CONCLUSION: AZ was comparable to SP for prevention of malaria in pregnancy and may be used in patients who do not tolerate SP.

Combined oral contraceptive pills for treatment of acne.

BACKGROUND: Acne is a common skin disorder among women. Although no uniform approach to the management of acne exists, combination oral contraceptives (COCs), which contain an estrogen and a progestin, often are prescribed for women. OBJECTIVES: To determine the effectiveness of combined oral contraceptives (COCs) for the treatment of facial acne compared to placebo or other active therapies. SEARCH METHODS: In January 2012, we searched for randomized controlled trials of COCs and acne in the computerized databases of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, POPLINE, and LILACS. We also searched for clinical trials in ClinicalTrials.gov and the International Clinical Trials Registry Platform (ICTRP) (Aug 2011). For the initial review, we wrote to researchers to seek any unpublished or published trials that we might have missed. SELECTION CRITERIA: We considered randomized controlled trials reported in any language that compared the effectiveness of a COC containing an estrogen and a progestin to placebo or another active therapy for acne in women. DATA COLLECTION AND ANALYSIS: We extracted data on facial lesion counts, both total and specific (i.e., open or closed comedones, papules, pustules and nodules); acne severity grades; global assessments by the clinician or the participant, and discontinuation due to adverse events. Data were entered and analyzed in RevMan. For continuous data, we calculated the mean difference (MD) and 95% confidence interval (CI). For dichotomous data, we calculated the Peto odds ratio (OR) and 95% CI. MAIN RESULTS: The review includes 31 trials with 12,579 participants. Of 24 comparisons made, 6 compared a COC to placebo, 17 different COCs, and 1 compared a COC to an antibiotic. Of nine placebo-controlled trials with data for analysis, all showed COCs reduced acne lesion counts, severity grades and self-assessed acne compared to placebo. A levonorgestrel-COC group had fewer total lesion counts (MD -9.98; 95% CI -16.51 to -3.45), inflammatory and non-inflammatory lesion counts, and were more likely to have a clinician assessment of clear or almost clear lesions and participant self-assessment of improved acne lesions. A norethindrone acetate COC had better results for clinician global assessment of no acne to mild acne (OR 1.86; 95% CI 1.32 to 2.62). In two combined trials, a norgestimate COC showed reduced total lesion counts (MD-9.32; 95% CI -14.19 to -4.45), reduced inflammatory lesion and comedones counts, and more with clinician assessment of improved acne. For two combined trials of a drospirenone COC, the investigators' assessment of clear or almost clear skin favored the drospirenone group (OR 3.02; 95% CI 1.99 to 4.59). In one trial, the drospirenone-COC group showed greater (more positive) percent changes for total lesion count (MD 29.08; 95% CI 3.13 to 55.03), inflammatory and non-inflammatory lesion counts, and papule and closed comedone counts. A dienogest-COC group had greater percentage decreases in total lesion count (MD -15.30; 95% CI -19.98 to -10.62) and inflammatory lesion count, and more women assessed with overall improvement of facial acne. A CMA-COC group had more 'responders,' those with 50% or greater decrease in facial papules and pustules (OR 2.31; 95% CI 1.50 to 3.55)Differences in the comparative effectiveness of COCs containing varying progestin types and dosages were less clear, and data were limited for any particular comparison. COCs that contained chlormadinone acetate or cyproterone acetate improved acne better than levonorgestrel. A COC with cyproterone acetate showed better acne outcomes than one with desogestrel, but the studies produced conflicting results. Likewise, levonorgestrel showed a slight improvement over desogestrel in acne outcomes, but results were not consistent. A drospirenone COC appeared to be more effective than norgestimate or nomegestrol acetate plus 17ß-estradiol but less effective than cyproterone acetate. AUTHORS' CONCLUSIONS: This update yielded six new trials but no change in conclusions. The six COCs evaluated in placebo-controlled trials are effective in reducing inflammatory and non-inflammatory facial acne lesions. Few important and consistent differences were found between COC types in their effectiveness for treating acne. How COCs compare to alternative acne treatments is unknown since only one trial addressed this issue. The use of standardized methods for assessing acne severity would help in synthesizing results across trials as well as aid in interpretation.

The impact of blood and seminal plasma zinc and copper concentrations on spermogram and hormonal changes in infertile Nigerian men.

Zinc (Zn) and copper (Cu) concentrations in sera and seminal plasma of 60 infertile males (40 oligozoospermic and 20 azoospermic) and 40 males with evidence of fertility (normozoospermic; controls) were estimated using atomic absorption spectrophotometry. The results were correlated with the subject's spermogram and hormonal levels in order to determine their relationship and significance in male infertility. The mean serum concentration of zinc was significantly (p<0.01) higher in oligozoospermic males when compared to azoospermic subjects and controls. The ratios of serum Zn to seminal plasma Zn were 1:1, 1:3 or 1:4 in oligozoospermic, normozoospermic or azoospermic subjects, respectively. While the mean Cu concentration was significantly higher in serum than seminal plasma in all groups, the Zn concentration was significantly (p<0.05) higher in seminal plasma than serum. The Cu/Zn ratio in seminal plasma was significantly (p<0.01) higher in controls compared with other groups. A significant (p<0.01) inverse correlation was observed between serum Zn and sperm counts. Similarly, seminal plasma Zn negatively correlated with spermatozoa viability. In conclusion, the measurement of serum Zn level, apart from being a good index of the assessment of prostatic secretion and function, may be considered a useful tool in addition to other parameters in assessing male infertility. Also, a lower Cu/Zn ratio in seminal plasma may serve as a supportive tools in assessing male infertility.

Effect of sublingual misoprostol versus intravenous oxytocin on reducing blood loss at cesarean section in Nigeria: a randomized controlled trial.

AIMS: The aim of this study was to compare the effectiveness and safety of sublingual misoprostol with i.v. oxytocin infusion administered after delivery in reducing blood loss at cesarean section in Nigeria. MATERIALS AND METHODS: One hundred women with term singleton pregnancy undergoing elective or emergency cesarean section under spinal anesthesia in Nigeria were randomly allocated to receive either misoprostol 400 µg sublingually or i.v. infusion of 20 units oxytocin soon after delivery of the baby. Estimated blood loss at surgery and within the first 4 h post-operation were measured in both groups. RESULTS: No significant difference was found in mean blood loss between the oxytocin and misoprostol groups. Similarly, no significant difference occurred between preoperative and postoperative hematocrit levels in both groups. The need for additional oxytocin was similar in both groups. There was significantly less blood loss in the first 4 h after surgery in the misoprostol group than in the oxytocin group (58.2 ± 20.7 vs 80.5 ± 26.8; P-value = 0.02). The incidence of adverse effects like shivering/pyrexia was significantly higher in the misoprostol group than in the oxytocin group (27/50 vs 1/50, P < 0.001). CONCLUSION: Sublingual misoprostol was as effective as i.v. oxytocin infusion in reducing blood loss at cesarean section. It offers several advantages over oxytocin, including long shelf life, stability at room temperature, and oral administration, which make it a suitable uterotonic agent in low-resource areas.

SEARCH STRATEGY: We searched for randomized controlled trials of COCs and acne in the computerized databases of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, POPLINE, and LILACS. We also searched for clinical trials in ClinicalTrials.gov and the International Clinical Trials Registry Platform (ICTRP). We wrote to authors of identified trials to seek any unpublished or published trials that we might have missed. SELECTION CRITERIA: All randomized controlled trials reported in any language that compared the effectiveness of a COC containing an estrogen and a progestin to placebo or another active therapy for acne in women were eligible. DATA COLLECTION AND ANALYSIS: We extracted data on total and specific (i.e., open or closed comedones, papules, pustules and nodules) facial lesion counts; acne severity grades; global assessments by the clinician or the participant and discontinuation due to adverse events. Data were entered and analyzed in RevMan. MAIN RESULTS: The search yielded 25 trials: 7 placebo-controlled trials made 4 different comparisons, 17 trials made 13 comparisons between 2 different COC regimens, and 1 additional trial compared a COC to an antibiotic. COCs reduced acne lesion counts, severity grades and self-assessed acne compared to placebo. Differences in the comparative effectiveness of COCs containing varying progestin types and dosages, though, were less clear. COCs that contained chlormadinone acetate or cyproterone acetate improved acne better than levonorgestrel, although this apparent advantage was based on limited data. A COC with cyproterone acetate might result in better acne outcomes than one with desogestrel; however, the three studies comparing these COCs produced conflicting results. Likewise, levonorgestrel showed a slight improvement over desogestrel in acne outcomes in one trial, but a second trial found the COC groups were similar. AUTHORS' CONCLUSIONS: The four COCs evaluated in placebo-controlled trials are effective in reducing inflammatory and non-inflammatory facial acne lesions. Few important differences were found between COC types in their effectiveness for treating acne. How COCs compare to alternative acne treatments is unknown since limited data were available regarding this question.

Oral misoprostol for the prevention of primary post-partum hemorrhage during third stage of labor.

AIM: To assess the effectiveness of oral misoprostol compared with methylergometrine in the prevention of primary post-partum hemorrhage during the third stage of labor. METHODS: This was a randomized controlled trial of 864 singleton low-risk pregnant women. The outcomes were total blood loss, duration of the third stage of labor and peripartal change in hematocrit. Comparisons were by the chi2-test and Student t-test. Relative risks were calculated for side-effects profile. A P-value of less than 0.05 was statistically significant. RESULTS: The biodata of all the participants were similar. The mean blood loss for the misoprostol and methylergometrine groups was 191.6 +/- 134.5 mL and 246.0 +/- 175.5 mL, respectively (95% CI: -79.3 to -39.5 mL). The mean duration of the third stage of labor was 19.6 +/- 2.4 min and 9.4 +/- 3.3 min in the misoprostol and methylergometrine groups, respectively (95% CI: 9.82-10.58 min). More subjects had blood loss >500 mL, 42 (9.7%) versus 6 (1.4%), and peripartal hematocrit change greater than 10%, 38 (8.8%) versus 5 (1.2%), in the methylergometrine group than in the misoprostol group, respectively. Also, more subjects received additional oxytocic in the methylergometrine group, compared to the misoprostol group (80 [18.5%] versus 33 [7.6%] patients, respectively). CONCLUSIONS: Orally administered misoprostol was more effective in reducing blood loss during the third stage of labor than intramuscular methylergometrine. However, there were more subjects in the misoprostol group in whom duration of the third stage of labor was greater than 15 min and who also had manual placental removal than in the methylergometrine group.

Effect of single administration of levonorgestrel on the menstrual cycle.

BACKGROUND: Levonorgestrel (LNG) 1.5 mg administered within 72 h of unprotected coitus is an established method of emergency contraception. Currently, there is some, although incomplete, knowledge about the mechanism of action. METHODS: We administered 1.5 mg LNG peri-ovulatory to determine the effects on serum gonadotrophins, estradiol and progesterone levels. Fourteen women were studied in a pretreatment and treatment cycle; eight women (Group A) took LNG 3 days before the expected day of ovulation, while 6 (Group B) took LNG a day before the expected day of ovulation. RESULTS: The women in Group A had a significant delay in their LH peak and onset of the next menses compared with their pretreatment cycles (26.4 vs. 39.1 days, p<.05). Those in Group B had no significant changes in the endocrine parameters but there was a significant shortening of the mean cycle length in comparison with their pretreatment cycles (25.1 vs. 20.2 days). CONCLUSION: Levonorgestrel 1.5 mg acts as an emergency contraception by delaying the LH surge and interfering with ovulation. It may also disrupt corpus luteum formation causing premature luteinization of unruptured follicles.

Cadmium toxicity: a possible cause of male infertility in Nigeria.

Serum and seminal plasma cadmium (Cd) concentrations were estimated by atomic absorption spectrophotometry in 60 infertile adult male Nigerians (40 oligozoospermics and 20 azoospermics). The results were compared with Cd level in 40 normozoospermic subjects (matched age, with proven evidence of fertility). The relationship between Cd levels and spermatograms or the hypothalamic-pituitary-gonadal (HPG) -axis was investigated by correlating serum and seminal plasma Cd levels with semen characteristics and hormone levels. The seminal plasma Cd level was significantly higher than those of serum in all studied groups (p<0.001). The serum and seminal plasma Cd levels were increased (p<0.001) in azoospermics in comparison to oligozoospermic and control subjects. A significant negative correlation was observed between serum Cd level and all examined biophysical semen characteristics except sperm volume. A positive correlation was also observed between seminal plasma Cd and FSH. Results of the study for the first time implicate cadmium as a cause of infertility in male Nigerians as well as extend and support previous findings concerning cadmium toxicity and male infertility. The strong deleterious effect of cadmium on spermatogenesis may be due to the systemic and cellular toxicity. A possible relationship between this element and the HPG axis is also suggested.
