Objective: To evaluate the pregnancy rate and time to pregnancy after timed coitus with or without superovulation in infertile young women younger than 35 years old with low serum $anti-M{\ddot{u}}llerian$ hormone (AMH) levels ( < 25th percentile). Methods: A total of 202 patients younger than 35 years old were recruited retrospectively between 2010 and 2012. Ninety-eight women had normal serum AMH levels (25-75th percentile), 75 women had low serum AMH levels (5th ${\leq}$ & < 25th percentile) and 29 women had very low serum AMH levels ( < 5th percentile), according to reference values for their age group. Results: The clinical pregnancy rate was positively associated with AMH levels, but this trend did not reach statistical significance (43.9% vs. 41.3% vs. 27.6% in the normal, low, and very low AMH groups, respectively). The time to pregnancy was longer in the very low AMH group than in the normal AMH group ($13.1{\pm}10.9months$ vs. $6.9{\pm}6.1months$, p= 0.030). The cumulative live birth rate over 18 months was lower in the very low AMH group than in the normal AMH group, with marginal significance (20.0% vs. 55.9%, p= 0.051). The duration of infertility was negatively correlated with achieving pregnancy (odds ratio, 0.953; 95% confidence interval, 0.914-0.994; p= 0.026). Conclusion: Conservative management, such as timed coitus with or without superovulation, should be considered in young patients who have low ovarian reserve without any infertility factors. However, for women with a long duration of infertility or very low serum AMH levels, active infertility treatment should be considered.

Klinefelter syndrome a genetic disorder with various clinical manifestations. Neurological symptoms, such as seizures, are rarely reported with Klinefelter syndrome, and it response well to anti-epileptic drugs. A 5-month-old boy visited the Inha university hospital due to jerking movements and hiccups. The patient had been diagnosed with Klinefelter syndrome at birth and had a medical history of admission to the neonatal intensive care unit due to opisthotonus and ocular deviation at 26 days of age. The patient's serum testosterone level was decreased and his anti-$M{\ddot{u}}llerian$ hormone level was increased. The brain image examination was normal and the electoencephalography and other blood test results showed no specific findings. However, after admission, the patient recurred generalized tonic-clonic-seizures recurred intermittently even after the administration of antiepileptic drugs. This paper reports a case of non-febrile seizures in a child with Klinefelter syndrome who presented with a refractory course.
