Basal serum 17α-hydroxyprogesterone (17-OHP) concentrations and the 17-OHP response
to acute adrenocorticotropic hormone administration were studied in infertile men with�…

Heterozygosity for 21-hydroxylase deficiency (21-OHD) was investigated in 174 adult hirsute
women by using the sum of the incremental responses of serum 17 α-hydroxyprogesterone�…

Combined results of 21‐DF (via the specific RIA method) and 17‐OHP levels in plasma were
used to support the evidence that some of the cases with idiopathic oligozoospermia (IO) are�…

A patient with 17a-hydroxylase deficiency (170HD) who continued to menstruate is reported.
A 24-year-old woman who presented with hypertension, hypokalemia and irregular menses�…

The plasma 17α-hydroxyprogesterone (17-OHP) concentration was determined in the basal
state and 60 minutes after cosyntropin, 0.25 mg, in 139 patients with idiopathic hirsutism (IH)�…

A sensitive and precise method, based on the technique of competitive proteinbinding, was
developed for measuring 17-hydroxyprogesterone (17-OHP) in peripheral blood. The�…

Abstract Plasma 17-hydroxyprogesterone (17-OHP) was measured by radioimmunoassay,
using an antibody preparation as specific binding reagent. One ml of plasma, with tritiated�…

A shortened approach to the measurement of 17α-hydroxyprogesterone (17-OHP) is
described. The extracted plasma sample with 3H indicator is purified by only one paper�…

One to 2% of hyperandrogenic women demonstrate a 17-hydroxyprogesterone (17-HP)
level greater than 36.3 nmol/L (1200 ng/dL) after acute ACTH–(l–24) adrenal stimulation�…

We treated two patients with male infertility due to 21-hydroxylase deficiency. Endocrinologic
examinations disclosed low levels of LH and FSH, with elevated ACTH and 17-OH�…
