An unusual cause of isolated secondary ovarian failure due to cerebral toxoplasmosis in an African woman with AIDS.

Primary ovarian failure is common. However, isolated secondary ovarian failure due to gonadotrophin deficiency is rare. A few cases of isolated gonadotrophin deficiency, due to congenital cerebral toxoplasmosis, have been described in children. We report the case of a 34-year-old African woman positive for HIV, who developed secondary amenorrhoea following the successful treatment of cerebral toxoplasmosis. Investigations revealed that she developed an isolated gonadotrophin deficiency due to pituitary lesion. The rest of the pituitary function dynamic tests were normal.

Genetics of primary ovarian insufficiency: a review.

Primary ovarian insufficiency is one of the main causes of female infertility owing to an abnormal ovarian reserve. Its relevance has increased in more recent years due to the fact that age of motherhood is being delayed in developed countries, with the risk of having either primary ovarian insufficiency or less chances of pregnancy when women consider the option of having their first baby. Several exogenous factors can lead to this event, such us viral infections, metabolomic dysfunction, autoimmune diseases, and environmental or iatrogenic factors, although in most cases the mechanism that leads to the disorder is unknown. Genetic factors represent the most commonly identified cause and the impact of sex chromosome abnormalities (e.g., Turner syndrome or X structural abnormalities), autosomal and X-linked mutations on the genesis of primary ovarian insufficiency has also been well described. Yet in most cases, the genetic origin remains unknown and there are multiple candidate genes. This review aims to collect all the genetic abnormalities and genes associated with syndromic and non syndromic primary ovarian insufficiency that have been published in the literature to date using the candidate-gene approach and a genome-wide analysis.

[Alterations of ovarian reserve tests in Human Immunodeficiency Virus (HIV)-infected women]. / Altérations des marqueurs de la réserve ovarienne chez les femmes infectées par le virus de l'immunodéficience humaine.

OBJECTIVES: Little is known about the impact of highly active antiretroviral therapy or HIV infection itself on the ovarian function. The aim of this study was to evaluate ovarian function in HIV-infected women in comparison with normal values from non-HIV infected women. PATIENTS AND METHODS: This is a prospective pilot study using markers of ovarian function: the antral follicular count (AFC) defined between cycle days 7 and 10 and follicle-stimulating hormone (FSH), inhibin B and antimüllerian hormone (AMH) for early follicular phase hormonal assessments. A descriptive analysis according to age was performed. RESULTS: Results from 78 HIV positive women are presented. AFC shows a high rate of abnormal values (63 %) occurring surprisingly early. The hormonal markers are concordant with a 36, 57 and 23 % abnormal rate for FSH, inhibin B and AMH respectively. DISCUSSION AND CONCLUSION: In our series, HIV seropositivity was associated with stigmas of premature ovarian insufficiency. This may explain impaired fertility but also suggests premature menopause in this population that should therefore be monitored early for such changes.
