Three hours after the final administration, blood The present invention is illustrated in more detail by was collected to separate the lymphocytes. The blasto way of the example and its effect clarified by way of the genesis of T lymphocytes against PHA (phytohemag test examples. 10 glutinin) was investigated by measuring labeled thymi dine incorporation. The results are shown in FIG. 1. EXAMPLE 1. It can be observed from FIG. 1 that by the anal ad ministration of prostaglandin E2 the immunological Estradio 10 mg competence in male rats only is lowered, that by the Vegetable oil q.s. to 10 ml 15 anal administration of prostaglandin D2 the immunolog ical competences in both male and female rats are low ered. Human semen contains a large amount of prosta EXAMPLE 2 glandin E derivatives (Table I). Therefore, the lowering of immunological competence in homosexual males 20 may be due to the absorption of seminal prostaglandins Estradio 100 mg through sexual activities. To make aqueous suspension (10 ml) by an ordinary EXAMPLE 8 (EFFECT OF SEX HORMONE) procedure. Male rats (Wister strain, 3 weeks old, male, n = 3) 25 were intrarectally administered with prostaglandin E2 EXAMPLE 3 at the rate of 0.5 mg/kg once a day for 7 days. Prior to this, they were dermatologically injected for seven days with testosterone (TES) or estradiol (EST) suspended 250 mg in olive oil at the rate of 1 mg/day. Seven days later, Vegetable oil q.s. to 10 ml blastogenesis of lymphocytes was determined in the same manner as in Experiment 1. The results are as shown in FIG. 2. EXAMPLE 4 From FIG. 2 it can be seen that testosterone and estradiol inhibit the lowering of the cellular immunity, 35 Methyl testosterone 10 mg and that the action thereof is the stronger with estradiol Lactose 48 mg than with testosterone.
