1.  Effects of short-term testosterone replacement on areal bone mineral density and bone turnover in young hypogonadal males 
Effect of parenteral testosterone esters administration on bone-mineral density (BMD) and bone turnover in young age onset male hypogonadism is not studied in Indian subjects.
To prospectively study the effect of short-term (6 months) replacement therapy with parenteral testosterone enanthate-propionate combination on BMD and bone turnover markers in hypogonadal adult patients.
Settings and Design:
Prospective, tertiary care academic center.
Materials and Methods:
Thirteen young, otherwise healthy hypogonadal males (age 25.5 ± 4.9 yrs, serum testosterone 2.56 ± 4.29 nmol/l) were subjected to BMD measurements (DXA) and estimation of urinary Crosslaps™ and serum osteocalcin at baseline. Twelve healthy age and BMI-matched males served as controls for BMD measurements. The hypogonadal patients were administered parenteral testosterone esters (as mixed enanthate and propionate) 250 mg i.m. every 2-3 weeks, and prospectively followed for 6 months. BMD and bone markers were studied at the end of 6 months.
Statistical Analysis Used:
Mann-Whitney nonparametric test, paired t-test and Pearson's test of two-tail significance.
At baseline, BMD was significantly lower in hypogonadal males as compared to that in controls. With testosterone replacement, there was significant improvement in BMD, both at trabecular and cortical sites, There was a decline in bone turnover with treatment (Ur Crosslaps™:creatinine ratio: pretreatment 72.8 ± 40.4, post-treatment 35.5 ± 23.8 μg/mmol, P = 0.098; serum osteocalcin: pre-treatment 41.0 ± 16.8, post-treatment 31.7 ± 2.1 ng/ml, P = 0.393).
Short-term parenteral testosterone replacement significantly improves BMD at the hip, lumbar spine and forearm in hypogonadal young males.

2.  Unique Case Reports Associated with Ovarian Failure: Necessity of Two Intact X Chromosomes 
Case Reports in Genetics  2012;2012:640563.
Premature ovarian failure is defined as the loss of functional follicles below the age of 40 years and the incidence of this abnormality is 0.1% among the 30–40 years age group. Unexplained POF is clinically recognized as amenorrhoea (>6 months) with low level of oestrogen and raised level of Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH > 20 IU/l) occurring before the age of 40. It has been studied earlier that chromosomal defects can impair ovarian development and its function. Since there is paucity of data on chromosomal defects in Indian women, an attempt is made to carry out cytogenetic evaluation in patients with ovarian failure. Cytogenetic analysis of women with ovarian defects revealed the chromosome abnormalities to be associated with 14% of the cases analyzed. Interestingly, majority of the abnormalities involved the X-chromosome and we report two unique abnormalities, (46,XXdel(Xq21-22) and q28) and (mos,45XO/46,X+ringX) involving X chromosome in association with ovarian failure. This study revealed novel X chromosome abnormalities associated with ovarian defects and these observations would be helpful in genetic counseling and apart from, infertility clinics using the information to decide suitable strategies to help such patients.
