The Compendium of Caraka 6.2.1

Now we shall expound the quarter on virilisation [beginning with] the roots of reed and arrow-grass.
A self-possessed man should constantly pursue virilisation,
for duty and wealth, as well as pleasure and fame, depend on it.
For this is the abode of a son, and these virtues rest upon sons;
and the foremost virilising field is an exhilarating woman.
For sense-objects are held to bring supreme delight when enjoyed one by one;
how much more so when established together in aggregate in a woman's body!
(For the aggregate of sense-objects is found in women, nowhere else.)
Indeed, the sense-object resting on a woman is exceedingly delight-producing;
delight resides especially in women, and in women offspring is established.
Duty and wealth are in women, and auspicious fortune, and the worlds are established in women.
She who is handsome, in the prime of youth, and adorned with auspicious marks,
who is compliant and well-trained—that woman is deemed most aphrodisiac.
Yet according to the varied inclination of humanity and by the conjunction of destiny in women,
qualities such as beauty flourish upon attaining this or that particular man.
That supreme woman who, through age, beauty, speech, and gestures,
swiftly enters his heart, whether by destiny or by karma;
who is the very form of a festival for the heart; who has matching thoughts;
who has a matching nature, is compliant, and is pleased with his beloved things;
who, through supreme qualities, has become a snare for all his senses;
separated from whom, he, finding no delight, regards the world as devoid of women;
without whom a man maintains a body as if empty of the senses;
seeing whom, a man is not overcome by grief, agitation, discontent, or fear;
attaining whom, he gains trust; seeing whom, he rejoices exceedingly;
whom he visits ever with supreme rush of excitement as if she were a new woman;
visiting whom repeatedly, having reached [her], he never attains satiety—
that woman is most aphrodisiac for him; for human beings have diverse natures.
A man free from disease, desiring offspring, should approach a woman
who is of a different lineage, virilising, cheerful, free from disorders, and freshly bathed after menstruation.
Just as a tree that gives no shade, has a single branch, bears no fruit,
and has an unpleasant odor stands alone, so too does a man without offspring.

A man without offspring is to be regarded as a painted lamp, a dried-up lake,
a non-metal resembling a metal, a bundle of grass in human form.
A man in whom offspring is not found is to be regarded as
unestablished, naked, empty, possessing only a single sense-organ, and inactive.
One with many offspring possesses many forms, many faces, many hosts, many actions,
many eyes, much knowledge, and many selves.
'This one is auspicious, this one is praiseworthy, this one is fortunate, this one is virile,
this one has many branches'—thus is a man with many offspring praised.
Delight, strength, happiness, livelihood, expansion, an extensive family,
[Variant: "prosperity,"]
fame, worlds culminating in happiness, and contentment—all are based on offspring.
Therefore, seeking offspring and the virtues that rest upon offspring,
and desiring the pleasures of desire, one should constantly adhere to virilisation.
Hereafter I shall declare the proven virilising combinations
that bring the happiness of enjoyment and increase virility and offspring.
Roots of arrow-grass and reed, kāṇḍekṣu, ikṣuvālikā,
śatāvarī, payasyā, vidārī, kaṇṭakārikā,
jīvantī, jīvaka, medā, vīrā, ṛṣabhaka, balā,
ṛddhi, gokṣuraka, rāsnā, ātmaguptā, and punarnavā:
take three-pala portions of these, and a fresh āḍhaka of māṣa beans;
[Variant: "having taken separate three-pala portions,"]
one should boil them in a droṇa of water and reduce it to a fourth.
The substances to be ground therein are madhuka, drākṣā, phalgu, pippalī,
ātmaguptā, madhūka, kharjūra, and śatāvarī;
and an āḍhaka of ghee, an āḍhaka each of the juice of
vidārī, āmalakī, and sugarcane, and a droṇa of milk, the physician should add;
he should cook it until only the ghee remains; then, well-strained, he should combine it
with powders of sugar and tugākṣīrī, each measured at a prastha,
with four palas of māgadhī and one pala of marica,
and with powders of cinnamon, cardamom, and saffron, each measured at half a pala,
and with two kuḍavas of honey. The physician should make it
into solid pills of one pala each; one should use them according to one's digestive power.
This formulation is supremely virilising, nourishing, and strength-promoting.

By this, powerful as an aroused horse, he can insert his penis.
(Thus ends the nourishing pill.)
One fresh āḍhaka of māṣa and seeds of ātmaguptā,
jīvaka, ṛṣabhaka, vīrā, medā, ṛddhi, śatāvarī,
madhuka, and aśvagandhā, measured at a kuḍava [each], should be cooked.
In that decoction, one prastha of ghee, ten times as much cow's milk,
one prastha of juice of vidārī, and a prastha of sugarcane juice—
having added these, it should be cooked over a gentle fire. When prepared, the ghee should be set aside.
Sugar, tugākṣīrī, and honey, each separately
in portions of four palas, and one pala of pippalī should be added to it.
Having licked one pala of this beforehand, one should then take food,
[he] who desires inexhaustible semen and supreme strength of the penis.
(Thus ends the virilising ghee.)
Sugar, split māṣa, tugākṣīrī, milk, ghee,
and wheat flour as the sixth—one should cook a pancake in ghee.
Crushing it while not overcooked, one should throw it into sweet chicken soup,
fragrant and hot, so that the soup becomes thick.
This piṇḍarasa is virilising, nourishing, and strength-promoting.
By this, powerful as an aroused horse, he can insert his penis.
The piṇḍarasa of peacock, partridge, and swan is considered likewise;
it produces strength, complexion, and voice, and through it a man becomes virile.
(Thus end the virilising piṇḍarasas.)
One should cook ghee and māṣa with goat testicles in buffalo soup;
one should fry that strained soup, soured with fruits, in fresh ghee,
lightly salted and mixed with coriander, cumin, and dry ginger.
This is virilising, strengthening, and nourishing—the best of soups.
(Thus ends the virilising buffalo soup.)
Sparrows in partridge soup, partridges in chicken soup,
chickens in peacock soup, and peacock in swan soup—
one should prepare these soups, heated in fresh ghee and soured with fruits,
or sweet, according to suitability, rich in fragrance and strength-promoting.
(Thus end the other virilising soups.)

Having attained satisfaction from sparrow meat, he who drinks milk afterwards—
for him there would be no flaccidity of the penis, nor loss of semen at night.
(Thus ends the virilising meat.)
Having eaten ṣaṣṭika rice rich in ghee with māṣa soup,
he who drinks milk stays awake the entire night with strong impulse.
(Thus ends the virilising māṣa formulation.)
A man does not sleep through the nights, with his penis constantly erect,
satisfied with chicken meat fried in crocodile semen.
(Thus ends the virilising chicken meat formulation.)
Having extracted the fluid of fish eggs, one should eat it fried in ghee;
likewise one should eat the eggs of swans, peacocks, and chickens.
Therefore, purification alone should be performed first according to strength, for virilising formulations
employed in an unclean body do not succeed, just as dyeing formulations [do not succeed] on dirty cloth.
Fifteen formulations that increase virility and offspring
have been declared in the quarter on the roots of reed and arrow-grass, granting nourishment and strength.
