Oligoasthenoteratozoospermia (OAT) is characterized as low sperm count, decreased sperm motility and structural abnormalities of the sperm head in the same patient. However, very few studies reported the genetic alterations associated with OAT. Here we report a 38-year-old patient with OAT from a consanguineous family, with 2-6 million/mL sperm density, 2.1-3.8% normal sperm morphology and immotile sperm. Whole-exome sequencing (WES) identified homozygous variant c.1259A>G:p.Y420C in the TDRD6 gene. TDRD6 is a testis-specific expressed protein that was localized to the chromatoid bodies in germ cells and played an important role in the nonsense-mediated decay pathway...

Background: Since 2010, three meta-analyses have been published on the impact of thyroid autoimmunity (TAI) on pregnancy outcomes in infertile women treated with assisted reproductive technology (ART). The initially observed high risk of miscarriage became very low in the most recent meta-analysis published in 2016. Objective: To investigate whether the lower risk of miscarriage in the latest meta-analysis was associated with the increased use of intracytoplasmic sperm injection (ICSI) in recent studies...

This article is a personal perspective on male infertility, a condition that is not only extremely prevalent but also a major reason for couples to resort to assisted reproductive technology. The introduction of intra-cytoplasmic sperm injection (ICSI) as a form of facilitated fertilization had a revolutionary impact on our capacity to treat cases of male infertility associated with severely-compromised semen quality. However, the widespread use of this technique is also thought to pose risks in terms of the incidence of miscarriage, the health and wellbeing of the offspring and perpetuation of the infertile phenotype into future generations...

OBJECTIVE: To analyze progesterone and prolactin plasma levels nine days after oocyte retrieval and evaluate their correlation with pregnancy rates in in vitro fertilization cycles. To achieve pregnancy, several factors are analyzed before and during the in vitro fertilization cycle. Progesterone supplementation for adequate luteal phase support is indicated despite the presence of multiple corpus luteum in IVF stimulation cycles because of blockage caused by hypothalamic agonists and antagonists...

Reproductive health services, including infertility care, are important in countries with infrastructure deficits, such as Lebanon, which now hosts more than one million Syrian refugees. Islamic prohibitions on child adoption and third-party reproductive assistance (donor eggs, sperm, embryos, and surrogacy) mean that most Muslim couples must turn to in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) to overcome their childlessness. Attempts to bring low-cost IVF-ICSI to underserved populations might help infertile couples where no other services are available...

PURPOSE: We examined whether short-term exposure to in vitro maturation (IVM) medium of cumulus-oocyte complexes (COCs) from a stimulated cycle increases the yield of metaphase II (MII) oocytes and usable embryos. METHODS: Retrospective review of two consecutive autologous IVF/ICSI cycles per patient between 2007 and 2015 in which cycle 1 did not result in live birth. Patients with short-term exposure of COCs to IVM medium (3-5 h before standard insemination or ICSI) in cycle 2 (treated) were matched 1:4 on %MI and %MII to patients without use of IVM in cycle 2 (untreated)...

The main goal was to evaluate the correlation between sperm parameters and chromatin quality with embryo kinetics via time-lapse monitoring system (TLM). A total of 40 couples involved in the ICSI program as a result of male infertility. For assessment of sperm chromatin and DNA quality, we used aniline blue, toluidine blue, chromomycin A3, acridine orange and terminal transferase-mediated deoxyuridine triphosphate biotin end labelling assays. All mature oocytes were injected, and the generated zygotes (2PNs) were cultured in TLM...
