ABSTRACT: It has been two decades since pregnancies have been obtained through in vitro maturation (IVM) of germinal vesicle-stage oocytes retrieved from non-stimulated ovaries. This technique first offered in PCOS cannot be recommended today in this indication because the results do not match those of regular ART, and new GnRH antagonist and agonist-trigger protocols reliably prevent OHSS.

ABSTRACT: STUDY QUESTION: Are anti-Müllerian hormone (AMH) levels lower in women with endometriosis, notably those with endometriomas (OMAs) and deep infiltrating lesions, compared with controls without endometriosis? SUMMARY ANSWER: Endometriosis and OMAs per se do not result in lower AMH levels. AMH levels are decreased in women with previous OMA surgery independently of the presence of current OMAs. WHAT IS KNOWN ALREADY: The impact of endometriosis and OMAs per se on the ovarian reserve is controversial. Most previous studies have been conducted in infertile women. The strength of our study lies in the following points: (i) the selection of women undergoing surgery and not only according to the presence of infertility, (ii) the classification of women with endometriosis and controls based on strict surgical and histological criteria. STUDY DESIGN, SIZE, DURATION: Cross-sectional study using data prospectively collected in all non-pregnant <42-year-old patients, who were surgically explored for a benign gynaecological condition at a university tertiary referral centre between 2004 and 2008. For each patient, a structured questionnaire was completed during a face-to-face interview conducted by the surgeon during the month preceding surgery. AMH levels were measured in serum samples drawn in the month preceding surgery, without regard to menstrual phase or hormonal therapy. PARTICIPANTS/MATERIALS, SETTING, METHODS: Operations were done on 1262 women between 2004 and 2008, of which 1133 signed the informed consent. Of the 566 women with a visual diagnosis of endometriosis, 411 had histologically proven endometriosis. Frozen serum samples for the AMH measurement were available in 313 of them. Out of the 554 women without visual endometriosis and without past endometriosis surgery, 413 had a frozen serum sample for the AMH measurement. Univariate analysis examined AMH levels according to baseline patient characteristics, the presence and type of endometriosis (superficial lesion, OMA, deep infiltrating lesion) and previous OMA surgery. Analysis of variance-covariance then examined the effects of co-variables on AMH levels. Finally, logistic regressions were conducted to examine the odds ratio (OR) of having AMH levels <1 ng/ml according to the same co-variables. MAIN RESULTS AND THE ROLE OF CHANCE: The difference in AMH levels between women with endometriosis and controls did not reach significance (3.6 ± 3.1 versus 4.1 ± 3.4 ng/ml, P = 0.06). Analysis of variance-covariance demonstrated that AMH levels significantly decreased with age (P < 0.001) and in women with prior OMA surgery irrespective of whether OMAs were present or not at the time of study (P < 0.05). Logistic regression revealed that two major factors were related to AMH levels <1 ng/ml: (i) age (compared with <29 years; 30-34 years OR = 3.1, 95% CI: 1.5-6.4, P = 0.01; 35-39 years OR = 7.0, 95% CI: 3.5-14.1, P = 0.001; ≥40 years OR = 20.8, 95% CI: 9.1-47.4, P = 0.001) and (ii) prior OMA surgery (OR = 3.0, 95% CI: 1.4-6.41, P = 0.01). LIMITATIONS, REASONS FOR CAUTION: The selection of our study population was based on a surgical diagnosis. Women with an asymptomatic form of endometriosis are therefore not included in our study. We cannot exclude that infertile women with OMAs associated with a diminished ovarian reserve, as assessed during their infertility work-up, were less likely to be referred for surgery and might therefore be underrepresented. WIDER IMPLICATIONS OF THE FINDINGS: Our findings suggest that OMAs per se do not diminish the ovarian reserve reflected by AMH levels but that alterations seen in women with endometriosis are a deleterious consequence of OMA surgery. These findings should be taken into account in the decision to operate OMAs in women with a desire for future pregnancy. STUDY FUNDING/COMPETING INTERESTS: Study funding: none. Potential competing interests: none.

ABSTRACT: In women with endometriosis, including those with endometriomas, 6 to 8 weeks of continuous use of oral contraception (OC) before assisted reproduction treatment (ART) maintains ART outcomes comparable with the outcomes of age-matched controls without endometriosis. In contrast, ART outcomes are markedly compromised in endometriosis patients who are not pretreated with OC. Ovarian responsiveness to stimulation was not altered by 6 to 8 weeks' use of pre-ART OC, including in poor responders with endometriomas.

ABSTRACT: To review 5 years of assisted reproductive treatments (ART) provided to couples affected by human immunodeficiency virus (HIV).
Age-matched cohort study.
University-based tertiary center.
Couples in whom the male (n = 87), female (n = 57), or both (n = 17) partners were HIV infected. The first ART cycle was compared with three sets of age-matched control subjects (3-to-1) which included 261, 171, and 51 couples, respectively.
ART in HIV-infected couples and age-matched controls.
Infertility duration and ART outcome.
When initiating ART, all three HIV-infected groups had longer infertility histories, computed from when conception was attempted or infertility diagnosed, compared with noninfected age-matched control subjects. Outcome, however, was not different when only the male or female partner was infected, though with a trend toward higher cancellation and lower pregnancy rates. When both partners were HIV infected, cancellation were higher and pregnancy rates lower (12% versus 41.2%), than in age-matched control subjects.
Our data showed longer infertility histories in all HIV-infected couples when undertaking their first ART. Outcome, however, was not altered when only one partner--male or female--was HIV infected. Efforts should therefore aim at assuring that HIV-infected couples access ART as promptly as their noninfected counterparts.

ABSTRACT: The aim of the present study, involving 463 women of reproductive age, was to evaluate for the first time the relationship between endometriosis, endometriosis-related infertility, and a recently described functional polymorphism in the ALOX15 gene, reported to be essential for implantation. In our study population, ALOX15 -292 C/T was not correlated either with the risk of developing an endometriosis or with the risk of infertility.
