Density Methods

Test tube baby is always a fascinating field of human reproductive biological science playing an important role in treating infertility. Poor semen quality is the major cause of infertility in human beings. Preparation of semen samples for intrauterine insemination (IUI) or in-vitro fertilization (IVF) is a key point in the success of test-tube embryo production. The study compared two different methods of semen preparation viz. double density gradient (DDG) and single density gradient (SDG) in patients seeking IUI / IVF treatment with their consent and permission of the hospital. Semen ejaculate from patients (n=100) was divided equally into two equal volume parts. One half of each sample was treated with DDG and another half with the SDG method of semen preparation. Results showed that sperm concentration was significantly higher (P>0.05) in SDG compared to DDG treated samples which were 58.65±181 and 49.89±180 Million/ml, respectively. Sperm motility of type-a and type-b both were significantly higher (P>0.05) in SDG compared to DDG treated samples which were 91.85± 3.15 and 68.85 ± 26.15. It is concluded that the single density gradient method is better than the double density gradient for semen ejaculates preparation during the treatment of male infertility using the in-vitro fertilization technique.

Vitro Fertilization

Assisted reproductive technology has shown rapid advancement since the birth of the first ‘test-tube’ baby in Oldham, UK, in 1978. Since April 2005, women between the ages of 23 and 39, who meet the described eligibility criteria, are able to get one free in vitro fertilization cycle funded by the National Health Service. Private treatment costs anything from £4000 to £8000 for a single cycle of treatment. Almost 15% of the couples in UK are affected by fertility problems and undergo detailed investigations before being offered assisted conception. Assisted reproduction is the collective name for treatments designed to lead to conception by means other than sexual intercourse. These include intrauterine insemination, in vitro fertilization, intracytoplasmic sperm injection and gamete donation. This review is intended to summarize the principles of assisted conception and examine the role of the biochemistry laboratory in: (A) the diagnosis and subsequent management of ovulatory disorders; (B) assessing ovarian reserve before initiating fertility treatment and (C) monitoring fertility treatment. It touches on the screening of potential gamete donors and follow-up of children born after assisted conception. This article was prepared at the invitation of the Clinical Sciences Reviews Committee of the Association of Clinical Biochemistry.

Vitro Fertilization

The human sperm head vacuoles and their role in male infertility are still poorly understood. The aim of this study was to identify the clinical and ultrastructural features of human sperm head vacuoles in men included in the in vitro fertilization programme: men with normal (normozoospermia) and impaired sperm morphology (teratozoospermia). The sperm samples were observed under 6000-time magnification using motile sperm organelle morphology examination (MSOME). The proportion of sperm with head vacuoles was evaluated and related to the outcome of in vitro fertilization. The sperm of men with impaired sperm morphology was characterized by a higher proportion of sperm head vacuoles. The sperm head vacuoles were related to impaired semen quality (sperm concentration, motility, and morphology) but were not influenced by male factors (semen volume, height, age, weight, or body mass index). Moreover, sperm head vacuoles were related to impaired fertilization rate merely after classical in vitro fertilization (IVF), while there was no relation to pregnancy. In a subgroup of men, the sperm was fixed and observed by transmission electron microscopy (TEM). The ultrastructural study revealed that sperm head vacuoles are large nuclear indentations of various sizes and positions, packed with membranous material organized in membrane whorls (MW).

Singleton Pregnancies

Women conceiving by assisted reproduction are at higher risk for preterm and premature rupture of membranes. The aim of our study was to estimate and compare incidence of preterm premature rupture of membranes in singleton pregnancies of women who conceived by intrauterine insemination and in vitro fertilization, from 1999 to 2003. We investigated 87 women from the intrauterine insemination, and 102 from the in vitro fertilization program. There were no statistically significant differences in regard to preterm and premature rupture of membranes: p>0.75 in two groups. The incidence of premature rupture of membranes was 2.30% (after intrauterine insemination) and 2.94% (after in vitro fertilization). There was no statistically significant differences in regard to preterm and premature rupture of membranes in women who conceived by insemination and in vitro fertilization. Estimated incidence of preterm and premature rupture of membranes was similar to the literature data and also similar to incidence after natural conception.
