In recent years, male infertility has become a growing social problem. Standard diagnostic procedures, based on assessing seminological parameters, are often insufficient to explain the causes of male infertility. Because of this, new markers with better clinical application are being sought. One of the promising markers seems to be an assessment of telomere length of sperm. Sperm telomeres, in contrast to somatic cells, are elongated as men age. The results of some studies suggest that telomere length may be relevant in the case of fertilization and normal embryo development...

Fertility levels and their determinants in Saudi Arabia have not been studied sufficiently for formulating family policy, although some attention has been paid to rapid fertility transitions in the context of socioeconomic and cultural change. This study focused on the fertility of a particular occupational category in the Kingdom of Saudi Arabia to assess determinants of fertility, measured as the number of children. The sample was drawn from the King Saud University staff - ever-married Saudi Arabian women...

When intended parents choose to have donor sperm treatment (DST), this may entail wide-ranging and long-lasting psychosocial implications related to the social parent not having a genetic tie with the child, how to disclose donor-conception and future donor contact. Counselling by qualified professionals is recommended to help intended parents cope with these implications. The objective of this study is to present findings and insights about how counsellors execute their counselling practices. We performed a qualitative study that included 13 counsellors working in the 11 clinics offering DST in the Netherlands...

This is a retrospective cohort study conducted in a national training centre for hysteroscopy between January 2012 and December 2014 to compare the clinical outcome of two doses of oestradiol valerate (4 mg and 10 mg daily) in the prevention of recurrence of adhesions after hysteroscopic adhesiolysis. A total of 176 women who suffered from Asherman syndrome with moderate to severe intrauterine adhesions were included: 91 subjects received a 10 mg daily dose of oestradiol and 85 subjects received a 4 mg daily dose of oestradiol in the postoperative period...

The aim of this study was to determine whether a continuous visual analogue scale (VAS) is a reliable tool to grade embryo transfer (ET) difficulty when assessing IVF outcomes. No standardized grading system exists for reporting ET 'difficulty' which is typically recorded in descriptive terms. Clinicians performing 188 fresh single ETs between November 2014 and May 2016 also recorded a VAS score (0-100). Embryo transfers were stratified into three levels of ET 'difficulty': (A) 'easy' - no resistance; (B) 'medium' - resistance overcome by advancing the catheter's outer sheath; and (C) 'difficult' - a malleable stylet was required to overcome resistance; and these compared to the VAS scores...

Trans fatty acids (TFAs) are thought to affect reproductive health by causing adverse effects on sperm morphology and ovum quality as a result of changing membrane lipid composition which, in turn, leads to impairment in metabolic pathways. This literature review examines the evidence for the effects of dietary TFAs on male and female infertility. Studies conducted between 2007 and 2017 on the effect of dietary TFAs on human reproductive health and fetal life have been included. They indicate that TFA intakes are inversely proportional to sperm concentration and total sperm count and exhibit a positive correlation with asthenospermia, as well as an adverse association on sperm concentration and semen quality...

Magnetic activated cell sorting (MACS) with annexin V microbeads deselected apoptotic sperm with externalized phosphatidylserine (PS) residues on their surface and decrease chance of such sperm to be inseminated. Therefore, the aim of this study was to evaluate efficiency of MACS procedure in a prospective randomized trial. Sixty-two semen samples were allocated into two groups and processed according to: (i) a combination of MACS with density gradient centrifugation (MACS-DGC) as study group (N = 29); and (ii) DGC alone as a control group (N = 33)...

Fertility preservation in the female poses several challenges due to the invasive nature of the techniques available to achieve it. The guideline aims to bring together the evidence available for the measures for fertility preservation and their outcome. The guideline addresses fertility preservation for medical reasons and includes both oncological and non-oncological causes. The techniques that the guideline considers are: (i) embryo and oocyte cryopreservation; (ii) ovarian tissue cryopreservation; (iii) GnRH agonist suppression and (iv) ovarian transposition...

This study investigated the efficacy of four published day 3 embryo time-lapse algorithms based on different types of datasets (known implantation data [KID] and single embryo transfer [SET]), and the confounding effect of female age and conventional embryo morphology. Four algorithms were retrospectively applied to three types of datasets generated at Fertility North between February 2013 and December 2014: (a) KID dataset (n = 270), (b) a subset of SET (n = 144, end-point = implantation), and (c) SET (n = 144, end-point = live birth), respectively...

This article describes a revised ovarian stimulation protocol (DuoStim) for fertility preservation in female oncology patients which aims to maximise the number of gametes obtained with subsequent improvement in cumulative birth rate, without delaying cancer treatment. Ten patients diagnosed with malignancy between September 2014 and October 2015 were included. The patients were treated with the DuoStim protocol, undergoing two consecutive ovarian stimulation cycles and two oocyte retrievals. The primary outcome was the number of oocytes collected and vitrified during each oocyte retrieval and in total...

Many questions arise concerning how infertility patients decide whether, how much and why or why not to consult more than one doctor and change physicians. To explore this issue, a total of 37 US in vitro fertilization (IVF) providers and patients were interviewed in-depth. Many infertility patients feel disappointed with infertility providers, especially after treatment failure, and then struggle to evaluate and weigh relative 'bedside manner' against technical skills, finances and hope, facing dilemmas of which doctor to choose, whether and how much, to 'shop around', how to do so, and whether and how much to give doctors 'second chances'...

The aim of this prospective study was to evaluate the relationship between morphometric parameters of metaphase II (MII) oocytes and the morphokinetic behaviour of subsequent embryos derived by intra-cytoplasmic sperm injection (ICSI). The association between oocyte morphometry: (whole oocyte), ooplasm, width of zona pellucida (ZP) and perivitelline space (PVS) and first polar body (PB) with embryo morphokinetic variables, including time of second PB extrusion (tPB2), pronuclei appearance (tPN), pronuclei fading (tPNf), formation of two to eight cells (t2 to t8) and irregular cleavage events [uneven at two cells stage, cell fusion (Fu) and trichomonas mitoses (TM)] were assessed...

In Australia, the growing assisted reproductive technologies (ART) industry has recently received some public criticism. Much of this criticism centres on the concern that doctors are increasingly motivated by profit, rather than patient interests. These concerns appear to suggest that the growing business of ART generates conflicts of interest (COI) for clinicians. While media reports may be rhetorically compelling, claims that ART practice is distorted by COI must be supported by empirical evidence. This preliminary study sought to engage with people involved with the ART industry and map out their concerns related to COI in ART...

The most common complication of pregnancy is idiopathic recurrent pregnancy loss (RPL). To identify the contribution of gene polymorphisms to this condition, we evaluated the association between RPL and the angiotensinogen (AGT), angiotensin receptor 1 (AGTR1) and Angiotensinogen converting enzyme (ACE). In this case-control study, the frequency of AGT (rs4762 and rs699), AGTR1 (rs5186) and ACE insertion/deletion (rs4340) polymorphisms in 202 idiopathic RPL women was compared with 210 women with no history of abortion, using tetra-primer ARMS-PCR...

The aim of this study was to evaluate accuracy, tolerability and side effects of office hysteroscopic-guided chromoperturbations in infertile women without anaesthesia. Forty-nine infertile women underwent the procedure to evaluate tubal patency and the uterine cavity. Women with unilateral or bilateral tubal stenosis at hysteroscopy with chromoperturbation, and women with bilateral tubal patency who did not conceive during the period of six months, underwent laparoscopy with chromoperturbation. The results obtained from hysteroscopy and laparoscopy in the assessment of tubal patency were compared...

In this study we investigate the association of C3953T transition single nucleotide polymorphism in the fifth exon of the interleukin 1β gene with idiopathic male infertility. In a case-control study, blood samples were collected from 230 fertile and 207 infertile men who referred to the Kashan IVF centre. Genotypes of samples at the C3953T location were determined by polymerase chain reaction-restriction fragment length polymorphism. The data showed a significant association of TT genotype (OR = 2.49, 95%CI = 1...
