6. Screening for Y-chromosome microdeletions in a population of infertile males in the Gaza Strip - Shaqalaih, Ashraf J.; Abu Halima, Masood S.; Ashour, Mohammed J.; Sharif, Fadel A.
Infertility is an extraordinary public health problem in the Arab world, as it affects about 15% of couples seeking children. The male partner is responsible for infertility in approximately half of these cases. Classic microdeletions of the Y-chromosome involving the azoospermia factor (AZF) regions are known to be associated with spermatogenic impairment, and non-obstructive azoospermia must be differentiated on the basis of endocrine evaluation and testicular biopsy. Partial AZFc deletions remain controversial because there is no clear agreement regarding their role in spermatogenic failure. In the current study, 50 fertile males (controls) and 125 patients with primary idiopathic male infertility...

7. Hyperfertility, obesity, and stillbirth: new considerations for clinical practice - Keith, Louis G.; Ngorima, Tawanda; Tsar, Olha M.
This research focuses on two well known phenomenon that regularly confront obstetricians on a worldwide basis. The first is hyperfertility, whose effects are well known within and outside the obstetrics community. The second is obesity, a problem of growing importance throughout the developed and developing world. Each is discussed in view of recently published evidence. In this work, we show how these two concepts interlock and how they represent a substantial clinical challenge to all physicians providing care to reproductive aged women.

9. Perinatal outcomes following transfer of human blastocysts vitrified at day 5, 6 and 7 - Hiraoka, Kenichiro; Hiraoka, Kaori; Miyazaki, Miyuki; Fukunaga, Emi; Horiuchi, Toshitaka; Kusuda, Tomoyo; Okano, Shinichiro; Kinutani, Masayuki; Kinutani, Kazuo
Little information is available on perinatal outcome of cryopreserved day-7 blastocyst transfer. In the present report, perinatal outcomes for transfers of cryopreserved blastocysts by a vitrification method were examined with respect to the day of blastocyst expansion among on day 5, 6 or 7 before cryopreservation. We investigated 263 cycles of vitrified-warmed blastocyst stage embryo transfer performed between April 2005 and April 2009, which were reviewed retrospectively. There were 144 cycles with day-5 blastocyst, 100 cycles with day-6 blastocyst, and 19 cycles with day-7 blastocyst transfers. There were no differences among the vitrified day-5, day-6 and day-7 blastocyst transfer groups...

12. Methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms resulting in suboptimal oocyte maturation: a discussion of folate status, neural tube defects, schizophrenia, and vasculopathy - Jongbloet, Piet Hein; Verbeek, André LM; den Heijer, Martin; Roeleveld, Nel
Several conditions apparent at birth, e.g., neural tube defects (NTDs) and cardiac anomalies, are associated with polymorphisms in folate-related genes, such as the 677C ? T polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene. Similar associations have been established for several constitutional chronic diseases in adulthood, such as schizophrenia, cardiovascular diseases, dementia, and even neoplasias in different organ systems. This spectrum of developmental anomalies and constitutional diseases may be linked to high-risk conceptions related to preovulatory overripeness ovopathy (PrOO). Some developmental anomalies, such as NTDs, are to a large extent prevented by supplementation of folic acid before conception, but supplementation does...

15. Paternal effects on early embryogenesis - Nanassy, Laszlo; Carrell, Douglas T
Historically, less attention has been paid to paternal effects on early embryogenesis than maternal effects. However, it is now apparent that certain male factor infertility phenotypes are associated with increased DNA fragmentation and/or chromosome aneuploidies that may compromise early embryonic development. In addition, there is a growing body of evidence that the fertilizing sperm has more function than just carrying an intact, haploid genome. The paternally inherited centrosome is essential for normal fertilization, and the success of higher order chromatin packaging may impact embryogenesis. Epigenetic modifications of sperm chromatin may contribute to the reprogramming of the genome, and sperm delivered...

16. Pregnancy following homologous prepubertal ovarian transplantation in the dog - Pullium, Jennifer K; Milner, Ross; Tuma, Gary A
In several canine models of hereditary human disease the homozygote dogs die prior to puberty, or have substantially reduced fertility. To create a clinically healthy animal that can be bred, but can also transmit the gene of interest, a model of homologous ovarian transplantation in prepubertal dogs was developed. Six dog leukocyte antigen (DLA) identical littermates underwent transplantation of ovarian cortical strips (n = 2) or the entire ovary (n = 4). Immunosuppression was maintained with cyclosporine and MMF in the immediate post-operative period and cyclosporine alone thereafter. All 6 dogs entered puberty and normal semiannual estrus cycles as demonstrated...

Regional clinical practice patterns in reproductive endocrinology: A collaborative transnational pilot survey of in vitro fertilization programs in the Middle East - Sills, Eric Scott; Qublan, Hussein S; Blumenfeld, Zeev; Dizaj, Ahmad VT; Revel, Ariel; Coskun, Serdar; Jaoude, Imad Abou; Serour, Gamal; Eskandar, Mamdoh; Khalili, Mohammad Ali; Demirol, Aygul; Trokoudes, Krinos; Ocal, Pelin; Sultan, Abdul Munaf; Lotto, Benjamin A; El-Kareh, Adele

18. Monozygotic multiple gestation following in vitro fertilization: analysis of seven cases from Japan - Yanaihara, Atsushi; Yorimitsu, Takeshi; Motoyama, Hiroshi; Watanabe, Hideaki; Kawamura, Toshihiro
We present a series of monozygous multiple gestations achieved following in vitro fertilization (IVF): one case of monochorionic triplet pregnancy and six cases of dizygotic triplet pregnancy. From September 2000 to December 2006, all patients achieving clinical pregnancy by ART were reviewed (n = 2433). A 37 year-old woman who delivered a healthy singleton after IVF returned two years later for FET, and a single blastocyst was transferred. This also resulted in pregnancy, but TV-USG revealed a single gestational sac with three distinct amniotic sacs, each containing a distinct fetal pole with cardiac activity. This pregnancy was electively terminated at...
