Birth experience of women conceiving with assisted reproduction: a prospective multicenter study.

OBJECTIVE: To determine how infertility and subsequent assisted reproductive treatment (ART) affect a woman's childbirth experience. DESIGN: Prospective multicenter case-control study. SETTING: We recruited women pregnant with a singleton fetus after either ART (n = 324) or spontaneous conception (n = 304) from five infertility clinics and one university maternity clinic in Finland. METHODS: We studied their childbirth experience with the Delivery Satisfaction Scale. We compared how psychosocial and obstetric factors affected satisfaction and dissatisfaction with childbirth between and within the ART and the control group. Logistic regression was then used to analyse the most important contributors to the experienced dissatisfaction. RESULTS: Dissatisfaction with childbirth was as common in the ART group (11%) as in the control (10%) group. In the ART group, the women's education level, cesarean section (CS) and their partner's absence from the delivery were associated with dissatisfaction. In the control group, significant factors for dissatisfaction were nulliparity, severe pregnancy-related anxiety, emergency CS, recalled intense pain and the partner's absence from the delivery. According to adjusted logistic regression analysis of the whole sample, the independent risk factors were elective CS [odds ratio (OR) 5.7; 95% confidence interval (CI) 2.2-14.1] and emergency CS (OR 2.9; 95% CI 1.3-6.5), recalled intense pain (OR 6.8; 95% CI 3.3-16.2) and the partner's absence from the delivery (OR 2.7; 95% CI 1.1-7.3). CONCLUSION: ART is not a risk factor for dissatisfaction with childbirth by itself. However, the contributors to an unsatisfactory childbirth differ partly between women conceiving with ART and those conceiving spontaneously.

Childbearing, the desire to have children, and awareness about the impact of age on female fertility among Finnish university students.

OBJECTIVE: To describe Finnish university students' childbearing histories, desires concerning childbearing, and awareness regarding the impact of age on female fertility. METHODS: A national survey of Finnish university students in 2008. A questionnaire was sent to 9,967 Finnish undergraduate university students aged less than 35 years. Altogether, the questionnaire was answered by 1,864 men and 3,222 women. The overall response rate was 51% (42% for men and 59% for women). Students were asked about their number of children, desired childbearing, and awareness of the effect of age on female fertility. RESULTS: Of the respondents, 8.25% had children, and 94.0% wanted to have children in the future. Female students were more aware of the impact of age on female fertility than were male students. Over half of the men and approximately one-third of the women thought that the marked decrease in female fertility begins after the age of 45 years. CONCLUSIONS: A vast majority of Finnish university students wanted to have children in the future. Their awareness of the natural, age-related decline in female fertility was insufficient. Sexual health education in schools and health care personnel's family planning counselling, for both men and women, should include information about the age-related drop in fertility.

Mental health of parents of twins conceived via assisted reproductive technology.

PURPOSE OF REVIEW: To review recent knowledge on mental health of parents of twins conceived via assisted reproductive technology (ART). RECENT FINDINGS: Mental health of mothers and fathers of twins conceived via ART is impaired when compared with that of ART singletons. SUMMARY: Existing studies are mainly cross-sectional and most of them focus on maternal mental health. It is evident that twin parenthood is the main factor impairing the mental health in parents with ART twins. This aspect should be taken into account when counseling the couples and deciding the number of embryos for transfer in ART. Well conducted prospective longitudinal studies are needed on both maternal and paternal mental health with twins conceived via ART from transition to parenthood to and beyond toddler age covering later life with school-aged and adolescent twins.

Prenatal expectations in transition to parenthood: former infertility and family dynamic considerations.

Prenatal expectations are important for the future parent-child relationship. The authors examined how maternal and paternal prenatal expectations of the relationship with the child predicted 1st-year parenting stress and whether these expectations were violated over the transition to parenthood. They further examined how former infertility affected these associations. The participants were 745 Finnish couples, 367 having undergone a successful assisted reproductive treatment and 378 conceiving spontaneously. Couples completed a questionnaire of family representations during pregnancy and when the child was 2 and 12 months old and Abidin's Parenting Stress Index at 2 and 12 months postpartum. The hypothesis of moderately high expectations predicting the lowest level of parenting stress was substantiated only concerning paternal expectations of own autonomy with the child. Generally, however, negative expectations of own and spouse's relationship with the child were linearly associated with higher parenting stress. Postnatal representations were more positive or equal to expectations, except for negative violation occurring in maternal expectation of the father-child relationship, especially among normative mothers. The results are discussed in relation to family dynamic considerations and special features of formerly infertile couples.

High and low BMI increase the risk of miscarriage after IVF/ICSI and FET.

BACKGROUND: The extremes of BMI are associated with an increased risk of miscarriage both in spontaneously conceived pregnancies and after fertility treatment. The aim of the present study was to study the effect of BMI on miscarriage rate (MR) in fresh IVF/ICSI, and in spontaneous and hormonally substituted frozen-thawed embryo (FET) cycles. METHODS: Analysis was carried out on 3330 first pregnancy cycles, performed during the years 1999-2004, of which 2198 were fresh, 666 were spontaneous and 466 were hormonally substituted FET cycles. A categorical, a linear and a quadratic models of the effect of BMI on miscarriage were studied by logistic regression. Factors related to patient characteristics, protocol and embryo parameters were also examined. RESULTS: MR was higher in hormonally substituted FET (23.0%), compared with the fresh cycles (13.8%) and spontaneous FET (11.4%, P < 0.0001). Multivariate logistic regression revealed that the relationship between BMI and the risk of miscarriage is not linear but quadratic (U-shaped) (P = 0.01), indicating a higher risk of miscarriage in underweight and obese women. Hormonal substitution for FET was also associated with a 1.7-fold higher MR, compared with the fresh cycles (P = 0.002, 95% confidence interval 1.2-2.3). CONCLUSIONS: Obese and underweight women have an increased risk of miscarriage, and hormonally substituted FET is associated with an even higher MR.

Five years of single embryo transfer with anonymous and non-anonymous oocyte donation.

Single embryo transfer (SET) has been the main embryo transfer strategy in the oocyte donation programme at the authors' clinic since 2000. The primary aim of this study was to evaluate the effect of SET on the clinical outcome in an unselected group of oocyte recipients. A retrospective analysis of the outcome in 142 recipient cycles (116 from anonymous donors; 26 from known donors) was performed. The oocytes from each anonymous donor were shared between two recipients if at least 10 oocytes were obtained. The proportion of SET of all fresh transfers was 77.3%. The clinical pregnancy rate (CPR) was 43.2% and the delivery rate 31.1% per embryo transfer. The outcome was similar in recipients undergoing anonymous and non-anonymous donation. The delivery rates were similar after SET (30.4%) or double embryo transfer (DET) (33.3%), whereas the twin rate was 0% after SET and 40% after DET. The implantation rate was significantly better (P < 0.01) with good-quality embryos (54.7%) compared with non-optimal embryos (27.1%). Of 152 frozen-thawed embryo transfer cycles, 78.9% were SET. The CPR was 28.3% and the twin rate was 7.1%. In fresh oocyte donation cycles, elective SET can be recommended if the embryo quality is considered good, and always if there is a contraindication for twin pregnancy.

Ante- and perinatal factors and child characteristics predicting parenting experience among formerly infertile couples during the child's first year: a controlled study.

In this prospective controlled study, the authors examined (a) parenting experiences among couples with successful assisted reproduction treatment (ART; n = 367) and fertile spontaneously conceiving controls (n = 371) and (b) the impact of ante- and perinatal factors and child characteristics on parenting experiences. The results show that positive mothering experiences increased more during the 1st year of parenting and were generally higher among ART mothers than control mothers. No differences were found between ART fathers and controls in their fathering experience. Unpleasant birth experiences, low birth weight, and difficulty soothing the child were associated with high levels of parental stress in the control group, but this was not so among the ART parents. Psychosocial interventions in maternal care should take into account the various meanings that couples give to the history of infertility and conception and ante- and perinatal experiences.

Maternal mental health and medical predictors of infant developmental and health problems from pregnancy to one year: does former infertility matter?

BACKGROUND: Transition to parenthood involves considerable psychological, social and physiological changes. We examined how prenatal and perinatal mental health and medical conditions predict infant's developmental and health status at 12 months, and whether former infertility and assisted reproduction treatment (ART) affect the predictor model. METHODS: The participants were 520 mothers who filled in questionnaires at the second trimester of pregnancy (T1), and when the child was 2 months (T2) and 12 months old (T3). Depressive and anxiety symptoms indicate reduced levels of mental health, and medical factors involve problems in pregnancy (e.g., high blood pressure and bleeding) and birth complications (pain and loss of blood). Neonatal health refers to, e.g., birth-weight and neurological status. At 12 months mothers reported infants' verbal and motor development and general health status. RESULTS: First, it was shown that generally maternal prenatal anxiety and medical problems in pregnancy together predicted infant's developmental problems at 12 months through poor neonatal health, and medical problems alone also through increased level of birth complications. Second, the predictor models differed according to the history of infertility. In the ART group prenatal depression and anxiety and medical problems together predicted infant's developmental problems through maternal post-partum depression, and medical problems also through birth complications, whereas in the spontaneous conception group psychological and medical paths were separated and did not carry on developmental and health problems into 12 months. CONCLUSIONS: Maternal health care should consider both psychological and medical risk paths across the whole transition to parenthood, and be aware of specific mediating paths in the risk groups.

Elective single embryo transfer in women aged 36-39 years.

BACKGROUND: The elective single embryo transfer policy is the only effective strategy known to minimize the risk of multiple pregnancy. However, little is known about its applicability to women older than 35 years. METHODS: Analysis was carried out on 1224 fresh IVF/ICSI cycles with embryo transfer and 828 frozen embryo transfer (FET) cycles of women aged 36-39 years. In the fresh cycles, 335 elective single top quality embryo (eSET), 110 elective single non top quality embryo (nt-eSET), 194 compulsory single embryo (cSET) and 585 double embryo transfers (DET) were carried out. RESULTS: Pregnancy rate/embryo transfer (33.1 versus 29.9%) and live birth rate (26.0 versus 21.9%) in fresh cycles did not differ significantly between the eSET and the DET groups. However, women in the eSET group had a higher cumulative pregnancy rate (54.0% versus 35.0%) and a higher cumulative live birth rate (41.8% versus 26.7%, P < 0.0001) compared with those in the DET group. The cumulative multiple birth rate in the eSET group was 1.7%, whereas in the DET group it was 16.6% (P < 0.0001). CONCLUSIONS: The eSET policy can be applied also to patients aged 36-39 years, reducing the risk of multiple birth and increasing the safety of assisted reproduction technique (ART) in this age group.

Elective single embryo transfer yields good delivery rates in oocyte donation.

BACKGROUND: High pregnancy rates have been noted after oocyte donation (OD). Multiple pregnancies should be avoided, because oocyte recipients have an increased risk of obstetric complications. METHODS: We analysed our OD results from 2000-2001 when elective single embryo transfer (eSET) was introduced as a recommended policy for all recipients if at least one good quality embryo was available. The results were compared with those achieved in 1998-1999, when usually two embryos were transferred (double embryo transfer, DET). Between 1998 and 2001, 100 healthy women donated oocytes and 135 fresh embryo transfers were carried out. The mean age of the donors was 31 years and that of the recipient women was 35 years. RESULTS: The proportion of eSET of all OD transfers was 17.1% in 1998-1999 and 61.0% in 2000-2001. There was no statistically significant difference in clinical pregnancy (36.8 versus 45.8%) and delivery rates (31.6 versus 33.9%) per embryo transfer between the two time periods. The proportion of twins declined from 29% (1998-1999) to 10% (2000-2001). The delivery rate was similar after eSET and DET (32.6 versus 32.1% respectively). CONCLUSIONS: By increasing the proportion of eSETs it is possible to reduce the number of twins without affecting delivery rates in oocyte recipients.

Effect of developmental stage of embryo at freezing on pregnancy outcome of frozen-thawed embryo transfer.

BACKGROUND: The study aim was to investigate the impact of the developmental stage of embryos on pregnancy outcome of frozen embryo transfer (FET). METHODS: The survival rates of embryos after thawing and pregnancy outcome following FET were compared retrospectively between three cryopreservation strategies utilizing either zygote, day 2 or day 3 embryo freezing. RESULTS: A total of 4006 embryos was analysed in 1657 thaw cycles. The highest (P < 0.0001) survival rate (all cells survived) was observed for zygotes (86.5%), followed by day 2 (61.7%) and day 3 (43.1%) embryos. FET was performed in 1586 (95.7%) of all thaw cycles, resulting in overall clinical pregnancy and implantation rates of 20.7 and 14.2% respectively. The delivery rate per transfer was 16.5%, and live birth rate per transferred embryo 11%. There were no significant differences in clinical pregnancy, implantation, delivery and birth rates between frozen zygote, day 2 and 3 embryo transfers. However, an elevated miscarriage rate was observed in the day 3 group (45%) compared with zygotes (21.3%; P = 0.049) and day 2 embryos (18.3%; P = 0.004). The overall efficacy of FET (birth rate per thawed embryo) was 7.3%. The efficacy was lower in day 3 group (4.2%) than in the zygote (7.1%; P = 0.082) and day 2 (7.6%; P = 0.027) groups. CONCLUSIONS: The developmental stage of embryos at freezing has a profound effect on their post-thaw survival, but seems to have little effect on rates of clinical pregnancy, implantation, delivery and birth after FET. The elevated miscarriage rate for day 3 frozen embryo transfers may be caused by damage during freeze-thaw procedures. The low survival rate and elevated miscarriage rate were both responsible for a reduced overall efficacy for day 3 FET when compared with zygotes and day 2 embryos.

Experience of in vitro fertilization surrogacy in Finland.

BACKGROUND: In vitro fertilization (IVF) surrogacy makes it possible for women who do not have a functional uterus to have their own genetic offspring. We describe here our experience of IVF surrogacy in Finland over a 10-year period. METHODS: This retrospective study included 17 women who underwent ovarian stimulation in connection with surrogacy in 1991-2001 at four clinics. The surrogate mothers were unpaid volunteers: six sisters, three mothers, one husband's sister, one cousin, four friends and three other volunteers. Thorough counseling was given to the commissioning couples and to the surrogate mothers and their partners. The commissioning couples were prepared to adopt their biological children. RESULTS: Twenty-eight surrogate IVF cycles were started in 17 women. One couple received donated oocytes. Trans-vaginal oocyte retrieval was feasible in every case, including those five women with congenital absence of the vagina and uterus. An average of 1.8 embryos was transferred at a time, and 11 pregnancies were achieved [50% per fresh embryo transfer (ET) and 16% per frozen-thawed ET]. Nine healthy singletons and one set of twins were born. One pregnancy ended in miscarriage. The mean birth weight of singleton infants was 3498 g (2270-4650 g). The birth weights of the twins were 2900 and 2400 g. In all cases the genetic parents took care of the infant immediately after birth. Two surrogate mothers had postpartum depression. CONCLUSIONS: Altruistic IVF surrogacy works well, but careful counseling of all parties involved is essential.
