Y chromosome microdeletions screening in Tunisian infertile men.

Y chromosome microdeletions screening in Tunisian infertile men. Ann Biol Clin (Paris). 2019 Sep 11;: Authors: Chabchoub I, Kdous M, Zhioua F, Gaied A, Merdassi G Abstract The aim of this study was to establish the prevalence of chromosomal abnormalities and microdeletions on the Y chromosome in Tunisian infertile men with severe oligozoospermia or non-obstructive azoospermia. In cases of azoospermia, we aimed also to correlate histological results after negative testicular sperm extraction with the type of Y chromosome microdeletion. 84 infertile patients and 52 controls were screened for karyotypic abnormalities using G-banding and Yq chromosome microdeletions using multiplex PCR. 7 infertile males (8.3%) carried chromosomal abnormalities and 8 (9.5%) presented Y chromosome microdeletions. The frequency of chromosome abnormalities in azoospermic patients was 11.1% vs 3.3% in the severe oligozoospermic group. Klinefelter syndrome was the most frequent chromosomal abnormalities in 85.7% of cases. Only one patient had a 46,X,del Y/45,X karyotype. The frequency of microdeletions was 11.1% in the azoospermic group and 6.7% in the severe oligozoospermic group. Six out of 84 (7.14%) of the infertile patients had microdeletions in the AZFc region, one azoospermic male had microdeletion in the AZFbc regions and one in the AZFb region, no deletions in the AZFa region. Among the 6 azoospermic patients with microdeletions: 4 had Sertoly cell only syndrome (SCOS) a...

Authors: Tvrdá E, Michalko J, Árvay J, Vukovic NL, Ivanišová E, Ďuračka M, Matušíková I, Kačániová M Abstract Schisandra chinensis is a woody vine native to China, Korea, and Russia, which has been used as a traditional herbal remedy to treat male infertility. As very little information is available concerning its effects on ejaculated spermatozoa, the aim of this study was to investigate the chemical, antioxidant, and antibacterial properties of the S. chinensis berry (Omija) extract followed by an assessment of its in vitro effects on bovine sperm ...

Conclusion: Satisfaction with the respect for the rights of users is strongly correlated with the other factors that are part of the concept of the organizational well-being of health care providers. The WWRR provides a means of measuring this important and often neglected dimension. PMID: 33029189 [PubMed]

Conclusion: Marked differences between Tunisia and Germany exist in public beliefs about the causes of mental disorders and their treatment, which correspond to differences in cultural orientations prevailing in these countries. Mental health professionals need to be sensitive to the particular cultural context in which they operate, in order to be able to reach those they intend to care for. PMID: 33029184 [PubMed]

AbstractBackgroundThe American Society of Clinical Oncology guidelines recommend early referral to reproductive endocrinology and infertility (REI) specialists for young women diagnosed with breast cancer. Current practice patterns demonstrate an increased utilization of neoadjuvant chemotherapy (NAC). We evaluated premenopausal women with breast cancer after consultation with a Fertility Nurse Specialist (FNS) and determine factors associated with referral to REI specialists.MethodsThis retrospective review included all premenopausal women diagnosed at our institution with stage 0 –III unilateral breast cancers betw...

Over the last years, increasing evidence has focused on crucial pathogenetic role of PRL on malignant, premalignant and benign uterine diseases. Studies in animals and humans have documented that PRL receptors (PRL-Rs) are widely expressed on uterine cells and that PRL is directly synthesized by the endometrium under the stimulatory action of progesterone. Uterine PRL secretion is finely modulated by autocrine/paracrine mechanisms which do not depend on the same control factors implied in the regulation of PRL secretion from pituitary. On the other hand, PRL is synthesized also in the myometrium and directly promotes uteri...

Abstract IntroductionTesticular microdissection sperm extraction (MD‐TESE) combined with intracytoplasmic sperm injection (ICSI) has made biological fatherhood possible for many men with the most severe form of male infertility, non‐obstructive azoospermia. MD‐TESE was introduced in Turku in 2008, and by 2015, 100 Finnish men with non‐obstructive azoospermia have been operated on. Material and methodsThe average age of the men was 33 years at the time of surgery. Forty‐eight had a needle biopsy previously and 56% had a testicular size

ConclusionsOur SRR is comparable with international results, and cumulative live birth rate similar to other ICSI indications in Finland. Physicians and specialists need to be made aware of new treatment options to enable biological fatherhood for men with non‐obstructive azoospermia.This article is protected by copyright.

CONCLUSIONS: The sperm retrieval rate and clinical pregnancy rate per initiated cycle in men undergoing in-vitro fertilisation and testicular sperm extraction in our unit were 44.9% and 13.5%, respectively. No sperms could be retrieved in the presence of AZFa and AZFb microdeletions, but karyotype and AZFc microdeletion abnormalities otherwise did not predict the success of sperm retrieval in couples undergoing in-vitro fertilisation and testicular sperm extraction. Genetic tests are important prior to testicular sperm extraction for patient selection and genetic counselling. PMID: 27687508 [PubMed - as supplied by publisher]
