The fiscal outcome of artificial conception in Brazil–creating citizens in developing countries
BACKGROUND
Infertility is an important health issue, but only a small fraction of the affected population receives treatment in Brazil, because it is not covered by the government or private health insurance plans. We developed a generational accounting-based mathematical model to assess the direct economic result of creating a citizen through IVF in different economic scenarios, and the potential economic benefit generated by the individual and his/her future offspring.
METHODS
A mathematical model analyzes the revenues and expenses of an IVF-conceived individual over his lifetime. We calculated the net present value (NPV) of an IVF-conceived citizen, and this value corresponds to the fiscal contribution to the government by an individual, from birth through his predicted life expectancy. The calculation used discount rates of 4.0 and 7.0% to depreciate the money value by time.
RESULTS
A 4.0% discount rate represents the most favorable economic scenario in Brazil, and it results in an NPV of US$ 61 428. A 7.0% discount rate represents a less favorable economic reality, and it results in a debit of U$ 563, but this debt may be compensated by his/her future offspring.
CONCLUSIONS
The fiscal contribution generated by each IVF-conceived citizen can justify an initial government investment in infertility treatment. Poor economic times in Brazil can sometimes result in a fiscal debt from each new IVF-conceived child, but this initial expenditure may be compensated by the fiscal contribution in the next generation.

Development of clinical priority access criteria for assisted reproduction and its evaluation on 1386 infertile couples in New Zealand
BACKGROUND
In New Zealand ranking patients for elective, publicly funded procedures uses clinical priority access criteria (CPAC). A CPAC to prioritize patients seeking assisted reproductive technology (ART) was developed in 1997 and implemented nationwide in 2000. This study describes the development of the ART CPAC tool and its evaluation on 1386 couples referred to a single tertiary service from 1998 to 2005.
METHODS
A total of 48 health professionals and consumers assisted in criteria development. A score between 0 and 100 points was calculated for each couple and those who reached ≥65 points were eligible for publicly funded ART. Couples beneath the treatment threshold were placed on active review; the review being the date the score was calculated to reach the treatment threshold. Couples who would never be eligible or who were on active review were offered private treatment. Treatments and outcomes (spontaneous and treatment dependent live birth pregnancies) were used to evaluate the criteria.
RESULTS
Three social criteria (duration infertility, number of children and sterilization status) and two objective criteria (diagnosis and female age) formed the priority score. Of the evaluated couples, 643 (46%) were eligible within 1 year of referral (Group 1), 451 (33%) >1–5 years from referral (Group 2) and 292 (21%) couples were never eligible (Group 3). The predominant ART was IVF. A total of 480 couples had at least one IVF treatment with 404 (84%) having publicly funded treatment. A total of 762 (55%) women gave birth, 473 from treatment and 289 spontaneously. Group 1 had more pregnancies from treatment while Group 2 had most pregnancies overall being mainly from spontaneous pregnancies. Compared with Group 3 cases the hazard ratio using time to spontaneous live birth pregnancy for Group 1 couples was significantly lower, 0.51 (95% confidence interval 0.36–0.74) and for Group 2 cases significantly higher, 1.86, (1.35–2.58). Treatments using ART were evaluated for the three eligibility groups, with the never eligible divided into women age <40 (Group 3a) and woman age ≥40 at referral (Group 3b). Compared with Group 1 cases the hazard ratio to treatment dependent live birth pregnancy was similar for Groups 2 and 3a but significantly lower for Group 3b (0.37, 0.14–0.90).
CONCLUSIONS
The clinical priority access score was able to discriminate between the chance of pregnancy with and without treatment and those offered and not offered treatment. The CPAC is a useful model for informing the allocation of public funding for ART in other countries.

Surrogate in vitro fertilization outcome in typical and atypical forms of Mayer-Rokitansky-Kuster-Hauser syndrome
BACKGROUND
The genital malformations in Mayer–Rokitansky–Küster–Hauser syndrome (MRKH) are frequently accompanied by associated malformations whose forms were recently classified as typical (isolated uterovaginal aplasia/hypoplasia) and atypical (the addition of malformations in the ovary or renal system). The aim of this study was to compare the surrogate IVF performance of women with typical and atypical forms including their chances of achieving pregnancy.
METHODS
The follow-up data on a total of 102 cycles of surrogate IVF in 27 MRKH patients treated in our department between 2000 and 2010 were analysed. Twenty patients with the typical form who underwent 72 IVF cycles were compared with seven patients with the atypical form who underwent 30 IVF cycles. The various examined parameters of these intended mothers were age, hormonal profile during controlled ovarian hyperstimulation and laboratory outcome.
RESULTS
The mean number of gonadotrophin ampoules needed for stimulation and treatment duration was significantly higher in the atypical form (3600 ± 1297IU for 13 ± 2.3 days versus 2975 ± 967 IU for 11.6 ± 1.6 days, P≤ 0.01). Serum estradiol and progesterone levels measured on the hCG administration day were similar. A significantly higher mean number of follicles 12.6 ± 6 versus 8.9 ± 5.4, P≤ 0.03, metaphase II (MII) oocytes 8.7 ± 5.1 versus 6.7 ± 4.8, P≤ 0.05, fertilizations 6 ± 3.6 versus 4.4 ± 3.3, P≤ 0.03 and cleaving embryos 5.7 ± 3.8 versus 4.1 ± 3.3, P≤ 0.01 were available in patients with the typical form compared with those with the atypical form, respectively. There was no significant difference in fertilization rate, cleavage rate or the mean number of transferred embryos. Embryo quality of the transferred ones and pregnancy rate per cycle were also similar between the two groups.
CONCLUSIONS
Women with the typical form of MRKH needed fewer gonadotrophins and for a shorter duration for ovarian hyperstimulation. The mean number of follicles, oocytes, MII oocytes, fertilizations and cleaving embryos was higher among women with the typical form. Pregnancy rates were similar since the available number and quality of transferred embryos to the surrogate mother were not affected.

Donor age is a major determinant of success of oocyte donation/recipient programme
BACKGROUND
In recent years, particularly in developed countries, women have tended to delay childbirth until over 40 years of age. Our study aims to identify whether the donor's age or recipient's age influences the pregnancy and live birth rate following oocyte recipient cycles.
METHODS
A population study included 3889 fresh oocyte recipient cycles. Pregnancy and live delivery rates were compared in recipient age groups (<35, 35–39, 40–44 and ≥45 years) and donor age groups (<30, 30–34, 35–39 and ≥40 years).
RESULTS
The highest live birth rate was of cycles in donors aged 30–34 years (25.0%), it decreased (P< 0.05) to 24.1% in donors aged <30 years, 20.7% in donors aged 35–39 years and 11.5% in donors aged ≥40 years. The multivariate analysis showed no significant differences in the success by recipient's age. Compared with cycles in donors aged 30–34 years, cycles in donors aged 35–39 years had 14 and 18% less chance to achieve a pregnancy [adjusted rate ratio (ARR) 0.86, 95% confidence interval (CI) 0.75–0.98] and a live delivery (ARR 0.82, 95% CI 0.71–0.96), while cycles in donors aged 40 years or older had 42 and 54% less chance to achieve a pregnancy (ARR 0.58, 95% CI 0.41–0.84) and a live delivery (ARR 0.46, 95% CI 0.29–0.73).
CONCLUSIONS
Older recipients with younger donors did not have a poorer pregnancy outcome compared with younger recipients with younger donors. Choosing a donor aged <35 years would increase the chance of pregnancy and live delivery for older recipients.

First experiences with hysterosalpingo-foam sonography (HyFoSy) for office tubal patency testing
BACKGROUND
This study was conducted to describe the first experiences with hysterosalpingo-foam sonography (HyFoSy) as a first step routine office procedure for tubal patency testing.
METHODS
A prospective observational cohort study was started in a university affiliated teaching hospital. In 2010, 73 patients with subfertility and a low risk of tubal pathology were examined. A non-toxic foam containing hydroxymethylcellulose and glycerol was applicated through a cervical applicator for contrast sonography (HyFoSy). Tubal patency was determined by transvaginal ultrasonographic demonstration of echogenic dispersion of foam in the Fallopian tube and/or the peritoneal cavity. Only in case patency could not be demonstrated, a hysterosalpingography (HSG) was performed as a control.
RESULTS
In 67 out of 73 (92%) patients, a successful procedure was performed. In 57 out of 73 (78%) cases, there was no further need for a HSG. In five patients (5/73; 7%) tubal occlusion was confirmed by HSG and in five patients (5/73; 7%) there was discordance between HyFoSy and HSG. Of 73 patients, 14 (19%) conceived within a median of 3 months after the procedure.
CONCLUSIONS
HyFoSy is a successful procedure to demonstrate tubal patency as a first step office procedure.
